    Fellow Adjoint of JILA and Retired/Emeritus Fellow of JILA, Peter Conti, has passed away. Conti died at the age of 87 due to complications from a car accident that occurred on June 12, 2021.
  • A model of isodensity contours for the surface density of the stellar disks for three galaxy models.
    When it comes to galaxies in our universe, there is still much work to do. Part of this work is being done by JILA Fellow and Assistant Professor of Astrophysics, Ann-Marie Madigan, and postdoc Dr. Angela Collier. In a  paper recently published in The Astrophysical Journal, Collier and Madigan postulate that the evolution of a galaxy can be affected by dark matter interacting with the stars within the galaxy. Galaxies evolve over billions of years, changing shape, speed of rotation, and other factors. Studying what affects galaxy evolution is important in answering questions about the foundation of our universe, of how stars and planets are formed, and the origins of dark matter.

    CU Boulder astrophysicist Ann-Marie Madigan has taken home a prestigious prize in recognition of her research exploring the dynamics of objects in space—from stars circling black holes to icy dwarf planets in the outer solar system.
  • Image of a black hole
    An international team of scientists, including a Թ of Colorado Boulder researcher, has taken the most detailed look yet at the supermassive black hole at the center of a galaxy called Messier 87. The results suggest the celestial object is surrounded by strong magnetic fields—key ingredients that could help generate galaxy-length jets of particles that shoot out around it.
  • Image of the first black hole pictured
    In a team of over 300 scientists, JILA Fellow and assistant professor in the Department of Astrophysical and Planetary Sciences, Jason Dexter digs further into the first picture ever taken of a black hole. His research has been recently published in a new paper for the Astrophysical Journal Letters.
  • An Image of the HAYSTAC system
    For nearly a century, scientists have worked to unravel the mystery of dark matter—an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect in experiments. Now, a team of researchers have used an innovative technique called “quantum squeezing” to dramatically speed up the search for one candidate for dark matter in the lab.

    The Richard Nelson Thomas Award was established by the friends and family of R.N. "Dick" Thomas to provide an annual award to the year's most outstanding graduate student in astrophysics. Each year, the JILA astrophysical faculty nominates outstanding students and vote to determine the recipient of the award.
  • Scientists have long struggled to explain the existence of the solar system's "detached objects," which have orbits that tilt like seesaws and often cluster in one part of the night sky.
    Within our solar system are icy planetary bodies that do not orbit the Sun. Astrophysicists want to understand why these orbital anomalies exist. Two recent studies by JILA Fellow Ann Marie Madigan's group suggest that these detached objects have steadily nudged themselves out of solar orbit over millions of years. Using supercomputers, the Madigan Group can test their theory of collective gravity.
