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.

Brainstorm: What stars can tell us about the universe
Brainstorm is a podcast by the Daily Northwestern which looks into scientific facts and fiction and the reasons why we believe in them. When you look up at the night sky, do you ever wonder where all those stars came from? Host Neya Thanikachalam spoke to CIERA’s Jeff Andrews to find out. The Daily Northwestern

This image shows the glow from a kilonova caused by the merger of two neutron stars. The kilonova, whose peak brightness reaches up to 10,000 times that of a classical nova, appears as a bright spot (indicated by the arrow) to the upper left of the host galaxy. The merger of the neutron stars is

SN 2019ehk
Artist’s interpretation of the calcium-rich supernova 2019ehk. Shown in orange is the calcium-rich material created in the explosion. Purple coloring represents gas shedded by the star right before the explosion, which then produced bright X-ray emission when the material collided with the supernova shockwave.
