Predicting Supernova Neutrino Spectra after Slow Collective Flavor Conversion
Prepared by Ian Padilla-Gay Neutrinos carry away most of the energy released in a core-collapse supernova. They cool the newly formed proto-neutron star, help heat material behind the stalled shock, […]

Hunting Dark Matter with Atom Gradiometers
Dark matter is one of the deepest mysteries in fundamental physics. While the existence of dark matter has been robustly established over the past decades through a combination of astronomical (e.g. the rotation of galaxies, the Bullet Cluster) and cosmological (e.g. anisotropies in the cosmic microwave background) observations, we still do not know what it is made of.

Whispers of the Stars: The Tale of ²³Na and Elusive Axions
In the crushing heat and density of stellar interiors, ordinary matter behaves in extraordinary ways, and, if some bold ideas in theoretical physics are correct, stars may also be producing entirely new kinds of particles: axions and axion-like particles, or ALPs.

The Secret Life of Neutrinos
Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun.
