Astrophysical Neutrino Sources as Colliders
Carlos A. Argüelles, P. S. Bhupal Dev, Bhaskar Dutta +6
High-energy neutrinos arise from processes at large center-of-mass energies, offering a window to test physics at comparable scales or beyond those accessible in collider experimen…
Dark matter energy exchange in stars orbiting supermassive black holes
Stephan A. Meighen-Berger, R. Andrew Gustafson, Nicole F. Bell +3
Stars on tight orbits around the supermassive black hole at the Galactic Center pass through regions where the dark matter~(DM) density may be strongly enhanced. We compute the orb…
The Cosmic Neutrino Background is within Reach of Future Neutrino Telescopes
Gonzalo Herrera, Shunsaku Horiuchi, Xiaolin Qi +1
The cosmic neutrino background (CB) can be boosted to high energies due to scatterings with energetic cosmic rays (CRs) across cosmological scales. Previous calculations focused…
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…
Cosmic-ray boosted inelastic dark matter from neutrino-emitting active galactic nuclei
R. Andrew Gustafson, Gonzalo Herrera, Mainak Mukhopadhyay +2
Cosmic rays may scatter off dark matter particles in active galactic nuclei, where both the densities of cosmic rays and dark matter are expected to be very large. These scattering…
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…
Cosmic-Ray Cooling in Active Galactic Nuclei as a New Probe of Inelastic Dark Matter
R. Andrew Gustafson, Gonzalo Herrera, Mainak Mukhopadhyay +2
We present a novel way to probe inelastic dark matter using cosmic-ray (CR) cooling in active galactic nuclei (AGNs). Dark matter (DM) in the vicinity of supermassive black holes m…
Detecting Boosted Dark Photons with Gaseous Detectors
Michael L. Graesser, R. Andrew Gustafson, Kate Hildebrandt +2
We search for indirect signals of (keV) dark matter annihilating or decaying into (eV) dark photons. These dark photons will be highly boosted and have de…
