CIERA Postdoctoral Fellow Haggard Published in Science Magazine

Daryl Haggard, CIERA Postdoctoral Fellow, has contributed to the study of our Galaxy’s central black hole in “Dissecting X-ray–Emitting Gas Around the Center of Our Galaxy”, a paper recently published in Science Magazine. Daryl is a co-author on this article, which examines X-ray emission from the Milky Way’s central supermassive black hole (the group was led by Daniel Wang, who was previously a Lindheimer Postdoctoral Fellow at Northwestern; he now works at University of Massachusetts, Amherst). The group showed that, counterintuitively, most of the X-ray emitting gas actually escapes the gravity of that massive central object. The article was also reviewed in a "Perspectives" piece in the same issue.

Postdoctoral Fellow Cowan Interviewed on Finding Life on Other Planets

Technology-news website, DVICE, interviewed CIERA postdoctoral fellow Cowan in their article "What's the most likely way we'll find life on other planets?" The article discards Hollywood's idea of extraterrestrial encounters and discusses theories that scientists have about looking for signs of life on exoplanets. Features astronomers look for include: a thick protective atmosphere, a solid surface, non-extreme temperatures and an infrared glow created by waste energy from life forms.


DePaul student writes about Farhad Yusef-Zadeh’s Research on Young Star Formation

Michelle M. Hunter, graduate student in Writing and Publishing at DePaul University, interviewed CIERA’s Farhad Yusef-Zadeh and wrote an article about his research, focusing on star formation in the hostile environment near the Supermassive Black Hole at the Galactic Center. Yusef-Zadeh theorizes, that while black holes have the ability to stretch a star-forming-cloud apart in one direction, they can also squeeze the cloud in another direction and actually create a star. This theory continues to gain favor over the previous theory that stars form elsewhere and later migrate near the black hole.

Study on Cloud Behavior Doubles Number of Potentially Habitable Planets

CIERA Postdoctoral Fellow Nicolas Cowan and University of Chicago researchers Jun Yang & Dorian Abbot have published a study in Astrophysical Journal Letters that could mean we have underestimated the number of Earth-like planets in the Galaxy. This study calculates the influence of cloud behavior on the climate in planets orbiting red dwarfs, the most common type of stars in the universe. Based on their findings, they have doubled the number of potential habitable planets, meaning that in the Milky Way galaxy alone there may be 60 billion planets orbiting red dwarf stars in the habitable zone. You can read the full article on Northwestern’s website. The paper can also be found online.

"Computational Thinking and Mathematical Modeling” Engages CPS Teachers

On May 13th, Reach for the Stars held “Computational Thinking and Mathematical Modeling”, a workshop that drew 35 middle and high school teachers and administrators from across the Chicago Public School District. This free, all-day event addressed questions such as: What are Computational Thinking and Mathematical Modeling? How are these skills utilized by university researchers? How can they be taught as part of the existing high school science and mathematics curricula? Are they already being taught? These questions were explored by speakers from Reach for the Stars, Net Logo and CT-STEM who specialize in a variety of areas including Astronomy, Physics, Biology, Chemistry, Mathematics, Physical Science, Earth Science and Computer Science. The workshop included presentations on the role Computational Thinking and Mathematical Modeling play in the Next Generation Science Standards, and break-out sessions where participants had the opportunity to choose from an assortment of small group presentations. Attendees left with a new set of ideas and tools with-which they can more effectively teach students various math and sciences.

Stars forming close to the Milky Way's central black hole
"An image showing the distribution of hot gas (here, in green) around our Milky Way's central black hole, labeled "Sgr A*".
The red and blue regions, revealed in new data from ALMA, show molecules usually associated with star formation;
the blue emission is especially quick moving gas, again characteristic of star formation."

Astronomers are still trying to understand how stars are born, but it seems that stars are fairly picky about where they form -- the matter cannot be too hot, or moving too quickly, for instance. Therefore, at the very center of our Galaxy, where mass is being pulled around by the Milky Way's central, supermassive black hole (a black hole with a mass about 4 million times that of the Sun), you might expect that forming stars would be very difficult. And, up until Friday, many astronomers would have agreed with you. However, Northwestern & CIERA Professor Farhad Yusef-Zadeh, along with Adjunct Associate Professor Doug Roberts, graduate student Marc Royster, and colleagues from across the world, have discovered the tell-tale signs of star formation very close to the Milky Way's central black hole. They have used an extraordinary new telescope in Chile (called ALMA, for the Atacama Large Millimeter/submillimeter Array) to trace the signature of molecules commonly found when stars form, and have now discovered those molecules from gas clouds near the Milky Way's central black hole. This discovery will not only help us understand the conditions under which stars can form, but also help us learn more about the environment around the central supermassive black hole in our Galaxy.

NU Astronomy: Listening to Black Holes

What are black holes? How can we be sure they exist? About a century ago, Einstein developed the now-accepted theory of gravity, known as General Relativity; black holes were predicted by that theory, and 40 years ago astronomers found some indirect evidence for their existence. However, it is now anticipated that direct proof of black holes will be found before the end of this decade: astronomers at Northwestern and the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) are involved in a race for the first direct detection of a new type of wave emission that originates strong from black holes. Dr. Kalogera will discuss this sound-like emission and how it will open a brand-new window onto the extreme universe of black holes and the warped space and time around them.

New Method to Map Extrasolar Planets
from CIERA Fellow, Dr. Nick Cowan

Astronomers have discovered almost 860 exoplanets to date: planets of many different sizes, orbiting different kinds of stars, at a wide range of distances from their parent stars. But for the most part, the details of those worlds are unknown to us -- are those planets covered in ice, water, or land, or some mix of those? The planets are too far away to answer these questions by simply taking pictures of them, even using the most powerful telescopes we have. We need clever tools to tease out what these planets look like.

CIERA Fellow Nick Cowan and Northwestern undergraduate Talia Strait have developed exactly this kind of tool. Presented at the Winter 2013 meeting of the American Astronomical Society, their technique uses reflected light to reconstruct the rough surface features of exoplanets. This method will help turn those exoplanets from data points into real worlds, allowing us to discover, for instance, how much of a planet is covered with oceans, or with land.

For an overview of this method, please see a news story at Inside Science News Service website.


JANUARY 2013

 

Dr. Nick Cowan describes how we'll find
Earth-like climates on other worlds

At the January 2013 meeting of the American Astronomical Society, astronomers working with NASA's Kepler spacecraft announced what may be the most Earth-like planet yet: the planet even orbits its parent star at just the right distance for water to exist on its surface. The detection of such a planet is very exciting, but what does the planet look like, and what would it be like to live there? To try to answer questions like these, we need to understand what the surface of the planet is like, and what its atmosphere is like. In a recent story on space.com, CIERA Fellow Nick Cowan describes this next step to understanding these planets: carefully watching them with large telescopes to tease out clues about water, land, and clouds on those worlds.


Prof. Farhad Yusef-Zadeh discovers new method
for detecting clouds and stars in Galaxy's center

Prof. Farhad Yusef-Zadeh has discovered a new method for detecting dusty clouds and stars in the center of our galaxy by taking an image using radio waves. He is the first to identify radio dark clouds and stars. Stars in the early and late phases of their evolution are shrouded by huge dusty envelopes in the form of dust and gas outflows. “When you see these dark stars or clouds in radio wavelength images, it tells you something very interesting,” Farhad said. “We immediately know there is a cold gas cloud or dusty star mixing with a hot radiative medium and that an interaction is taking place. Knowing details of these clouds is important because the clouds can produce stars and also provide material for the growth of black holes.”
Unlike in the optical, X-ray and infrared wavelengths, it is unusual to see a dark feature with radio waves. Radio is a long wavelength and therefore doesn’t get absorbed easily and typically passes through whatever is in its way. Astronomers can measure the size of dusty stars using this new technique. The interaction of a cold dust cloud with a hot radiation field results in a loss in the continuum emission and appears as a dark feature in the radio wavelength image, Farhad said. The dark features that trace the embedded molecular clouds provide astronomers with the size of the cloud in three dimensions.
For his study, Farhad used Green Bank Telescope maps and Very Large Array images from the National Radio Astronomy Observatory. The National Science Foundation (grant AST-0807400) supported the research. His paper, published in the November 1 issue of The Astrophysical Journal Letters, is "Imprints of Molecular Clouds in Radio Continuum Images." Also see "Detecting Dusty Clouds and Stars in Our Galaxy" by Megan Fellman from the Northwestern University News.


Dr. Daryl Haggard Elected to Help Lead

In this year's election, CIERA Postdoctoral Fellow Daryl Haggard was elected to the Executive Committee, for a term of three years. In her work on that Committee, Daryl aims to draw early-career researchers to the Division, and to improve the connection between high-energy astrophysicists and those studying lower-energy phenomena.

Congratulations Daryl!


Dr. Nate Kaib's paper, "Planetary system disruption
by Galactic perturbations to wide binary stars",
published in Nature

CIERA Postdoctoral fellow, Dr. Nate Kaib's paper, "Planetary system disruption by Galactic perturbations to wide binary stars", was published in Nature magazine. Here is the abstract for the paper:

Nearly half the exoplanets found within binary star systems reside in very wide binaries with average stellar separations greater than 1,000 astronomical units (one astronomical unit (AU) being the Earth–Sun distance), yet the influence of such distant binary companions on planetary evolution remains largely unstudied. Unlike their tighter counterparts, the stellar orbits of wide binaries continually change under the influence of the Milky Way’s tidal field and impulses from other passing stars. Here we report numerical simulations demonstrating that the variable nature of wide binary star orbits dramatically reshapes the planetary systems they host, typically billions of years after formation. Contrary to previous understanding2, wide binary companions may often strongly perturb planetary systems, triggering planetary ejections and increasing the orbital eccentricities of surviving planets. Although hitherto not recognized, orbits of giant exoplanets within wide binaries are statistically more eccentric than those around isolated stars. Both eccentricity distributions are well reproduced when we assume that isolated stars and wide binaries host similar planetary systems whose outermost giant planets are scattered beyond about 10 AU from their parent stars by early internal instabilities. Consequently, our results suggest that although wide binaries eventually remove the most distant planets from many planetary systems, most isolated giant exoplanet systems harbour additional distant, still undetected planets.

You can learn about the research that went into this paper by Dr. Kaib and his team at Northwestern University News.

Good Work Nate!

Dr. Laura Trouille accepts joint position between NU and Adler

Dr. Laura Trouille has accepted a joint position between Northwestern University and the Adler Planetarium! She has already started working in that capacity, working half-time at CIERA (where she will continue both her research and outreach work, as a CIERA Fellow), and half-time at Adler.

She will be working in Adler's education and outreach programs, as well as continuing her own research in AGN at Adler. So, if you are interested in volunteering at Adler, or have questions about Adler programs and visitors, or the connections between NU and Adler, Laura is an excellent person to ask.

Congratulations, Laura!


Ever want to ask an astronaut a question? Now's your chance!

In celebration of the 40th anniversary of the Apollo mission, the Adler Planetarium is hosting a number of events, including interviews with Apollo astronauts Harrison Schmitt and Eugene Cernan.

We're currently compiling possible questions to ask the astronauts, about spaceflight, being on the moon, the history and future of manned space exploration, etc. If you have questions for our Apollo astronauts that you'd love to hear them answer, please email them to Dr. Laura Trouille at l-trouille@northwestern.edu. All questions accepted, from serious to entertaining.

Powerful Computer Cluster for use on Gravitational Wave Simulations
to be Installed at Northwestern

In October, Northwestern's Quest Supercomputer will get 1344 additional computer "cores" (computer processors) as well as 32 high-performance graphics cards for use in specialized numerical simulations. With all of this computing power comes 37 TB of new disk space: the computers and disk space will be used to explore gravitational-wave source simulations and data analysis. Undergraduate and graduate students will also be trained in high-performance computer on this new resource.

This computer cluster comes to Northwestern as the result of a collaborative effort of many groups on campus. The group was led by Prof. Vicky Kalogera, included many faculty who are a part of CIERA (Profs. Alok Choudhary, Erik Luijten, Fred Rasio), and was made possible by the Northwestern University IT group (including past Associate Director for Research Computing Thomas Hauser and current Assoc. Director Joseph Paris), the Weinberg College of Arts and Sciences, the McCormick School of Engineering and Applied Science, the Vice President for Research at Northwestern, and the Departments of Electrical Engineering and Computer Science, Materials Science, Engineering Science, and Physics & Astronomy.


Prof. Vicky Kalogera appointed to the Scientific Advisory Board
for the Max Planck Institute for Gravitational Physics!

Prof. Vicky Kalogera was appointed as a member of the Scientific Advisory Board for the Max Planck Institute for Gravitational Physics in Potsdam, Germany.

The Institute’s scientific advisory and assessment Board is made up of internationally renowned physicists. The Board advises the President of the Max Planck Society (MPG) on how effectively the Directors are managing the work of the Institute. Their advice helps the Directors to establish priorities and improve their management. The Scientific Advisory Board is the main tool used by the MPG to evaluate its research institutes to ensure appropriate and effective development of funds. Every two years the members of the Board meet for several days to evaluate the Institute and to prepare a report to the President of the MPG.
