A coherent story of the Universe from galaxy and CMB surveys

January 31, 2023

Combining data from the Dark Energy Survey and the South Pole Telescope, scientists piece together a coherent story of the Universe from galaxy and CMB surveys. These are some of the most stringent tests of the standard cosmological model using cross-correlations of independent data sets.

Robert Rosner likes big questions.
How could nuclear power help humanity in a warming climate? How can physicists better explain their work to the public? And why are magnetic fields… well, everywhere? “The nerve of them, being so ubiquitous,” he says.

Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky.

“Meet astronomy and astrophysics student, Mandy Chen”, PSD News

January 5, 2023

Mandy Chen was born and raised in Guizhou Province, Southwest China. Before coming to the University of Chicago she was studying at the University of Hong Kong, where she got bachelor’s and master’s degrees in physics and astronomy. This is her fifth year as a PhD student in astronomy and astrophysics. Her research focuses on observations of the diffuse circumgalactic medium—the outermost envelopes of galaxies. She says she “seeks to better understand the dynamical state of this diffuse gas, and its connection to the star-formation/supermassive blackhole activities of galaxies and the cosmic baryon cycle in general.”
