Astrophysics

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.

Cold Coulomb Crystals, Cosmic Clues: Unraveling the Mysteries of Space Chemistry

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties…

New Findings From the JWST: How Black Holes Switched from Creating to Quenching Stars

Astronomers have long sought to understand the early universe, and thanks to the James Webb Space Telescope (JWST), a critical piece of the puzzle has emerged. The telescope's infrared detecting “eyes” have spotted an array of small, red dots, identified as some of the earliest galaxies formed in the universe. 

This surprising discovery…

Questions about Quasars: How to Best Weigh a Celestial Body

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…
