For Dan Hooper, head of theoretical astrophysics at the Fermi National Accelerator Laboratory, Chicago, solving these questions involves radically rethinking what we think we know about the universe’s very early history.

PUEO is a balloon mission designed to launch from Antarctica that will detect signals from ultra-high energy neutrinos, particles that contain valuable clues about the highest energy astrophysical processes, including the creation of black holes and neutron star mergers. Neutrinos travel across the universe undisturbed, carrying information about events billions of light years away. PUEO would be the most sensitive survey of cosmic ultra-high energy neutrinos ever conducted. The principal investigator is Abigail Vieregg of the University of Chicago.

UChicago scientist lays out how LIGO gravitational waves could be scrambled, yielding information.
“Gravitational waves are the perfect messenger to see these possible modifications of gravity, if they exist.”—Astrophysicist Jose María Ezquiaga

He has accepted a position as a Consultant at Bain & Company in Chicago, and in this capacity he will focus on strategy and management.

XENON1T data could be either evidence of new particle physics or unexpected contaminant.

Fermilab, UChicago scientists tap South Pole Telescope data to shed light on universe

A team of scientists have demonstrated how to "weigh" galaxy clusters using light from the earliest moments of the universe - a new method that could help shed light on dark matter, dark energy and other mysteries of the cosmos, such as how the universe formed.

A new solar telescope in Hawaii has captured images of the sun unlike any seen before.  Professor Robert Rosner, an astrophysicist at the University of Chicago and one of the lead investigators on the project, says he’s been waiting for almost 40 years to see images like the ones recently captured.

In a forthcoming paper, UChicago scientists announce a new measurement of the universe’s expansion that uses red giant stars.
