Fundamental physics with high-energy and ultra-high-energy cosmic neutrinos High-energy cosmic neutrinos probe fundamental physics at scales of energy and distance otherwise unreachable, where new physics may manifest. Since the discovery of TeV-PeV astrophysical neutrinos in 2013, we have explored this progressively more broadly and with increasing precision, thanks to a...

You’re sending particles across a country? The Tokai to Kamioka experiment Neutrinos are a tiny subatomic particle with surprising properties under active study. In particular, neutrinos oscillate, that is, they convert from one type of neutrino to another, is a surprising phenomenon under active study. The origin of neutrino mass...

Gamma Rays from the Littlest Galaxies: Tracing Accretion and Dark Matter in the Low-Mass Universe Now in its 17th year of operation, the Fermi Large Area Telescope (LAT) continues to transform our understanding of the smallest galaxies in the Universe. Dwarf galaxies host some of the most extreme environments known---from ultra-faint systems...

Prospects for pulsars and pulsar associations in multi-messenger astrophysics with population synthesis Population synthesis seeks to integrate the full framework of stellar evolution with predictions for observations of different products of said evolution, potentially allowing constraints to be placed on multiple evolutionary steps at the same time. It has become a...
