Analysis of cosmic microwave background reinforces Hubble constant measurement

The APS Fellowship Program was created to recognize members who may have made advances in physics through original research and publication, or made significant innovative contributions in the application of physics to science and technology. They may also have made significant contributions to the teaching of physics or service and participation in the activities of the Society.

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). 

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.

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.

John Carlstrom, Subramanyan Chandrasekhar Distinguished Service Professor in the Departments of Astronomy & Astrophysics and Physics, the Enrico Fermi Institute, and the College, receives this prize in recognition of his critical contributions to the Physical Sciences Division and the continued success of both academic departments.

Gabriel Hoshino, PhD student, was awarded the DOE’s Office of Science Graduate Student Research (SCGSR) Fellowship to work with Prof. David Miller, Andrew Sonnenschein, and  Stefan Knirck on "Instrumentation for a Terahertz Reflector-Based Search for Axions and Dark Photon”  
 

New data on the cosmic microwave background released from upgrade with 10 times more detectors

My main science research is of an observational nature, concerning Galactic and intergalactic interstellar gas. Highlights for me included my work on the orbiting telescope Copernicus, including the discovery of interstellar deuterium; early observations of absorption associated with five-times ionized oxygen; and discoveries concerning the phases of gas in the local interstellar medium, based on previously unobservable interstellar UV spectral lines.

Angela Olinto, Dean of the Physical Sciences Division, and Professor in A&A, EFI, and Senior Member of the KICP will become the next provost of Columbia University.

Discovery by UChicago astrophysicists may change our picture of how stars explode and elements are made

University of Chicago astrophysicist celebrated for work investigating the cosmic microwave background for clues about the early universe.
