Analysis of cosmic microwave background reinforces Hubble constant measurement

UChicago-led analysis measures universe expansion rate, finds there may not be a ‘Hubble tension’
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the “Hubble constant” —have come up with different answers, leading some to wonder if there was something missing from our model of how the universe works.

Astronomy & Astrophysics and KICP Professor and FNAL Senior Scientist Dan Hooper has been selected as the new director of the Wisconsin IceCube Particle Astrophysics Center (WIPAC). 

Congratulations to Elyssa Brooks for successfully defending her Ph.D. dissertation on "Developments of Microwave Kinetic Inductance Detectors".

Every now and then, tiny particles of antimatter strike Earth from cosmic parts unknown. A new balloon-borne experiment launching this spring may at last find their source.

CCAPP is proud to announce Abigail Lee (U. Chicago) and Hanjue Zhu (U. Chicago) as the winners of the 2024 Price Prize in Cosmology and Astrophysics

Prof. Freedman is a Canadian-American cosmologist at the University of Chicago who works in the area of refining measurement of the Hubble Constant. She is renowned for her work on Cepheid variable stars through a Hubble Space Telescope Key Project. Her work and accomplishments are closely connected to the big-bang theory of Georges Lemaître.

“We suspected that magnetic fields are acting as the walls of the chimney and that hot gas is traveling up through them, like smoke”, said Scott Mackey of the University of Chicago, who led the study. “Now we’ve discovered an exhaust vent near the top of the chimney.”
