JILA astrophysicists investigate a broad range of topics including the evolution of stars, the formation of planets, the dynamics of black holes, and even the fundamental properties that give rise to the Universe itself.
JILA’s astrophysics research is aided by data gathered by ground- and space-based instruments. Our researchers use this astronomical data to test and refine theoretical simulations of processes that occur in our solar system and throughout the Universe.

Recent Highlights in Astrophysics

In a new paper in The Astrophysical Journal, JILA Fellow Jason Dexter, graduate student Kirk Long, and other collaborators compared two main theoretical models for emission data for a specific quasar, 3C 273. Using these theoretical models, astrophysicists like…

For a new study, a team of physicists recruited roughly 1,000 undergraduate students at CU Boulder to help answer one of the most enduring questions about the sun: How does the star’s outermost atmosphere, or “corona,” get so hot?

The research represents a nearly-unprecedented feat of data analysis: From 2020 to 2022, the small army of…

For decades, black holes have fascinated scientists and nonscientists alike. Their ominous voids, like an open pair of jaws, has inspired a whole wave of science-fiction featuring the phenomenon. Physicists have also been similarly inspired, specifically to understand the dynamics of what is happening inside of the black hole, especially for…
