An ultraporous humidity sponge could provide 300 gallons of fresh water a day. UChicago computational chemist Prof. Laura Gagliardi is using molecular simulations and precise experimental measurements to figure out how this material might capture even more water even more easily.

Asst. Prof. Edwin Kite comments on Martian ‘lake’ at Gale Crater

Planetary scientist Asst. Prof. Edwin Kite comments on the NASA Curiosity Mars rover landing site, Gale Crater, and the question of whether it was once a massive and long-lasting lake or only a series of smaller, transient puddles.

Black holes have tantrums, and scientists have finally captured the resulting gamma rays

November 17, 2021

An artist’s conception of a supermassive black hole at the center of a galaxy that is spewing out jets (shown in orange) as well as via ultra-fast outflows of ionized gas (shown in gray/blue).

A group of scientists announced they had detected the gamma rays from a phenomenon known as an ultra-fast outflow—a powerful wind launched from very near a supermassive black hole—for the first time. Scientists believe these outflows play an important role in regulating the growth of the black hole itself and its host galaxy.

In this introduction to why quantum computing will transform the digital world as we know it, the Chicagoland region is featured for leading the charge with the Chicago Quantum Exchange—which “draws on the expertise and vision of world-class universities, exceptional government laboratories and visionary industry leaders to advance research and development of quantum technologies.”

Massive, colliding black holes may expand along with the universe

A team of scientists that includes Kavli Institute for Cosmological Physics Hubble Fellow Michael Zevin may have solved the mystery of how most massive black holes are formed. The team proposes that black holes with masses that were previously unexplainable could be growing hand-in-hand with the accelerating expansion of the Universe. The phenomenon could be an example of what the team calls "cosmological coupling."

Meet physics student, Carlos Sierra

November 15, 2021

Carlos Sierra

Carlos Sierra was born in Santa Ana, California, and grew up in the nearby city of Anaheim. Before coming to the University of Chicago, he attended Fullerton College, a community college in Southern California, and transferred to UC Berkeley, where he received his bachelor’s degree in physics. Afterwards, he started a doctoral program in applied physics at the University of Michigan, Ann Arbor. After three years he moved with the McMahon group to UChicago, where he will complete his doctoral research in the Department of Physics. He is currently in his fifth year and conducting research in experimental cosmology. He develops and tests instruments for the Simons Observatory, a series of telescopes that will soon be making precise measurements of the Cosmic Microwave Background (CMB) from high atop the Atacama Desert in Chile.

A new result is stirring the debate around WIMPs, or Weakly Interacting Massive Particles. Astrophysicist Dan Hooper comments on the search for WIMPs underground, suggesting the COSINE-100 experiment “is the nail in the coffin” of dark matter interpretations from the DAMA/LIBRA, which claimed to have spotted the elusive dark matter particle in 2017.
