Stars are the fundamental building blocks and probes of the Universe. They are formed in stellar nurseries enshrouded by dust and gas, and end their lives in violent explosions, creating some of the most captivating events one can witness. Faculty in CIERA study, model, and observe many stages of a star’s life from birth to death, the planets formed around them, how they impact their environments, as well as the compact remnants they leave behind.
Research at CIERA
Evolving to the end states of stellar evolution, Professor Fong’s team uses radio and optical observations to study and model relativistic explosions called gamma-ray bursts and their host galaxy environments, probing star formation from the local neighborhood to the high-redshift Universe.
Professor Tchekhovskoy uses state-of-the-art simulations to study the formation of relativistic jets in core-collapse gamma ray bursts.
Professor Miller’s group uses ground- and space-based telescopes to study the endpoints of the stellar life cycle as punctuated by supernovae. The group uses data science methods, such as machine learning, to support the discovery and classification of these explosions prior to studying their properties in greater detail.
Professor Figueroa-Feliciano’s group studies the X-ray signatures of supernova remnants through the NASA Micro-X Sounding Rocket, a Northwestern-led rocket payload which takes high-energy-resolution spectra of remnants in suborbital flights.
Professor Kilpatrick uses optical, infrared, and X-ray imaging of nearby galaxies to understand the stellar channels that lead to their cataclysmic collapse and explosion as supernovae, focusing on deep, high-resolution imaging and spectroscopy that can be used to study their local environments, nucleosynthetic content, and progenitor stars.

NGC 261 captured by Hubble
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA’s Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way’s closest galactic companions, the Small Magellanic Cloud (SMC). The ionized gas blazing from within this

Sun’s magnetic field originates surprisingly close to the surface
Sun’s magnetic field originates surprisingly close to the surface
On May 22, 2024 an international team of researchers, including CIERA Professor Daniel Lecoanet, published a paper in Nature that brings scientists closer than ever before to solving a 400-year-old solar mystery that stumped even famed astronomer Galileo Galilei. Since first observing the sun’s magnetic activity, astronomers have struggled to pinpoint where the process originates.

Witch Head Nebula and Rigel
Witch Head Nebula and Rigel
Near Rigel, a bright star found in the constellation Orion, lies the Witch Head Nebula (look closely to see the face!). This nebula is a reflection nebula– a cloud of dust that is lit up by nearby stars. Rigel’s starlight reflects off the dust to light up this very faint nebula. Photographer and CIERA graduate

Eagle Nebula with the Pillars of Creation
This is a picture of the Eagle Nebula, a magnificent emission nebula. At the heart of the Eagle Nebula are the Pillars of Creation, famously photographed by the Hubble Space Telescope in 1995, and recently by the James Webb Space Telescope. In this image, photographer and CIERA graduate student Imran Sultan depicts the Eagle Nebula
