Princeton University Gravity Initiative Seminar

Connecting Dense Matter to Astrophysical Compact Objects
Isaac Legred
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: Neutron stars and black holes represent the inevitable endpoints of stellar evolution for high-mass stars. Despite the apparent fine-tuning of the physical conditions necessary to produce them, neutron stars are abundant in the Galaxy. On...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

On the Origins of Cosmic Rays
Damiano Caprioli
11:00am|Peyton Hall Auditorium

The origin of extraterrestrial energetic particles ("cosmic rays") has puzzled scientists since the pioneering discovery by Victor Hess in 1912. In the last decade, however, modern supercomputers and multi-wavelength observations have opened new...

Princeton University Dark Cosmos Seminar

Low-Mass Galaxies as Probes of Dark Matter Physics
Niusha Ahvazi
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: Dwarf galaxies, despite (or perhaps because of) their small masses, are puzzles that challenge prevailing cosmological models. As the most common galaxies in the universe, they offer a powerful window into studying dark matter on the...

Princeton University Donald R. Hamilton Colloquium Series

The Search for Axion Dark Matter
Benjamin Safdi
4:00pm|Jadwin Hall A-10

Abstract: Axions are some of the best-motivated beyond the Standard Model particle candidates at present. These ultralight particles may account for the cosmological dark matter and explain other outstanding problems in nature, such as the strong-CP...

Princeton University Gravity Initiative Seminar

Instabilities of near-extremal black branes
Alex Buchel
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: Extremal horizons (and associated emergent quantum criticality of the corresponding holographic models) receive strong quantum corrections at very low temperatures.  We point out that when such models are embedded in top-down holography...
