Probing Dark Matter Interactions with Stellar Motion near Sagittarius A*
R. Andrew Gustafson, Ian M. Shoemaker, Volodymyr Takhistov
Stars orbiting Sgr A* at the Milky Way's center provide a unique laboratory to test gravity and dark matter (DM). We demonstrate that DM interactions in stellar interiors induce a…
Sub-GeV Dark Matter Under Pressure from Direct Detection
Andrew Cheek, Pablo Figueroa, Gonzalo Herrera +1
The DAMIC-M collaboration recently reported impressive bounds on sub-GeV dark matter, robustly testing both thermal and non-thermal models for the very first time. In this work we…
Nucleon Decays into Light New Particles in Neutrino Detectors
Julian Heeck, Ian M. Shoemaker
Proton and neutron decays into light new particles can drastically change the experimental signatures and benefit from the complementarity of large water-Cherenkov neutrino det…
The Dark Matter Diffused Supernova Neutrino Background
Garv Chauhan, R. Andrew Gustafson, Gonzalo Herrera +2
We consider neutrinos scattering off Milky Way dark matter and the impact of this scattering on supernovae neutrinos. This can take the form of attenuation on the initial flux of n…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Supernova Gamma-Ray Constraints from Heavy Sterile Neutrino Decays
Garv Chauhan, R. Andrew Gustafson, Ian M. Shoemaker
Heavy sterile neutrinos can be produced in core-collapse supernovae (CCSNe), which are superb particle generators because of their high densities and temperatures. If the sterile n…
