My research lies at the intersection of cosmology and general relativity, most of the time involving simulations. Usually, our cosmological simulations of large-scale structure formation make assumptions about the nature of gravity and space-time. These simulations are extremely important to our understanding of the Universe in regimes we cannot access analytically.

Prof. Abigail Vieregg and her students build instruments to detect the highest energy neutrinos.

Abigail Vieregg received a Moore Foundation Experimental Physics Investigators Initiative Award for instrumentation development to advance the detection of the highest energy neutrinos.

I work broadly within the realm of gravitational-wave astronomy. Nearly infinitesimal ripples in the fabric of spacetime, gravitational waves are generated by the most cataclysmic events in the Universe, including the explosions of stars and the relativistic collisions of black holes.

I work on the detection of ultra-high energy neutrinos by measuring the radio signals that are emitted when they interact in glacial ice in Greenland or Antarctica.

Research: Circumgalactic Medium and Warm-Hot Intergalactic Medium; Quasar Absorption Lines; X-ray and Sunyaev–Zeldovich Effect.

I work on field theoretic aspects of de Sitter (dS) space, and its relation to the physics of inflation.

In their new paper, Holz and first author Jose María Ezquiaga suggest that they can use our newfound knowledge about the whole population of black holes as a calibration tool.

Leah is a theoretical physicist whose research lies at the intersections of cosmology, gravitational physics and high-energy physics.

A Carnegie-led effort secured $205 million toward the completion of the next-generation Giant Magellan Telescope, which is currently being built at our Las Campanas Observatory in Chile. When completed, the GMT will enable breakthrough astronomy—from revealing the fundamental physics underpinning the cosmos to advancing our ability to search for life on distant worlds.
