Short gamma-ray bursts traced farther into distant universe

A Northwestern University-led team of astronomers has developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers, including Anya Nugent, pinpointed the galactic homes of 84 SGRBs and probed the characteristics of 69 of the identified host galaxies.

Bad Astra Interviews Maya Fishbach

Maya Fishbach uses gravitational waves to probe the universe’s most extreme objects — black holes and neutron stars. Her research aims to understand where, when and how these systems of merging compact objects are made. As a member of the LIGO Scientific Collaboration, she analyzes gravitational-wave data to study the population properties of colliding black

LIGO-Virgo-KAGRA Discoveries Over Time

This animation shows the increasing sample of gravitational wave sources, starting before LIGO-Virgo-KAGRA went online (with only electromagnetic, EM, sources) and then moving through the three main data releases that are now available (GTWC-1, GWTC-2.1, and GWTC-3).  Watch as the sample of merging black holes and neutron stars has dramatically increased over the past few

LIGO and Beyond

Interview

LIGO and Beyond

Episode 8 of the documentary series “LIGO: The Discovery that Shook the World” features CIERA Director Vicky Kalogera discussing the science of future LIGO instruments (the detectors that observe gravitational waves). All 8 episodes can be found on YouTube.  

The Advanced LIGO Documentary Project was a collaboration among Caltech, MIT, the LIGO Laboratory and director Les Guthman that made the feature documentary, “LIGO,” and the eight-part video series, THE DISCOVERY THAT SHOOK THE WORLD, about LIGO’s major gravitational wave discoveries 2015-2017 and the birth of the new era of gravitational wave astronomy.

CIERA’s 10th Annual Public Lecture, “The NU Astronomy of Stars, Black Holes, and Cosmic Explosions”

CIERA’s 10th annual public lecture was presented October 11, 2018 by director Vicky Kalogera. Kalogera’s talk–a glimpse into the years of fascinating work conducted by CIERA–highlighted key discoveries and what they mean for the future of astronomy. Kalogera discussed the lives of stars, how their influence on the Cosmos has changed in the recent decade,

How Do You Detect a Black Hole? LIGO and the Measurement of Gravitational Waves

Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we may soon have the first picture of the
