NASA’s Roman Space Telescope will investigate the history of galaxies
Robyn Sanderson and collaborators are unearthing the history of the universe’s formation by looking for clues that reveal its ‘galactic fossil record.’
Yhe universe is a dynamic, ever-changing place where galaxies are dancing, merging, and changing appearance. Looking ever deeper into the universe, astronomers see galaxies at earlier stages in their lives. Unfortunately, because these changes take millions or billions of years, telescopes only provide snapshots, squeezed into a human lifetime.
The dominant model of the universe is creaking: Dark energy could break it apart
The Economist quotes Bhuvnesh Jain in their recent science and technology article.
Strange observations of galaxies challenge ideas about dark matter
ScienceNews quotes Bhuvnesh Jain in their recent article about dark matter.
“I think it’s a real stretch to say that one can do away with dark matter, because the lines of evidence [for it] are so numerous,” says Bhuvnesh Jain, a cosmologist at the University of Pennsylvania.

Prof. Vijay Balasubramanian discusses time on Netflix series Explained
Vijay Balasubramanian, Cathy and Marc Lasry Professor and Center for Particle Cosmology faculty, was featured on the episode "Time" of the Netflix series Explained. The episode delved into the individual experience of time, the evolutionary pressures of time, and how we understand time as it relates to space and the universe. Prof. Balasubramanian explains that "matter and energy can bend space.
With help from Prof. Cullen Blake NEID spectrometer fully operational
The new NEID spectrometer at the WIYN Observatory is fully operational after taking it's first observations in January 2020. Thanks to a team of scientists including Prof. Cullen Blake, CfPC faculty and Associate Professor in the Department of Physics and Astronomy, NASA and NSF are accepting proposals to utilize this powerful new tool. “There’s a huge number of proposals, with lots of really interesting stuff—even some outside of the box sorts of things.
CfPC Co-Director Bhuvnesh Jain talks about the increasingly important role of "big data" in astronomical research
Bhuvnesh Jain, Walter H. and Leonore C. Annenberg Professor in the Natural Sciences and Co-Director of the Penn Center for Particle Cosmology, talked to Omnia, the magazine of Penn's School of Arts and Sciences, about what drew him to astrophysics as a child and the important role that big data and data analysis has played in cutting edge research in astronomy and cosmology today.
Center faculty, staff, and students contribute to "most precise 3D map of the universe to date"
Faculty, research staff, and students from the Center for Particle Cosmology and the Department of Physics and Astronomy have contributed to the efforts of the Dark Energy Survey, a global collaboration to better understand the role of dark matter and dark energy in the universe. The collaboration includes Professors Gary Bernstein, Bhuvnesh Jain, and Masao Sako along with other scholars and students. Dr.
New stellar stream, born outside the Milky Way, discovered with machine learning
Finding this new collection of stars, named after Nyx, the Greek goddess of night, was made possible using machine learning tools and simulations of data collected by the Gaia space observatory.
