5. Constraining Non-Annihilating Ultra-Heavy Dark Matter through Exoplanets

Exoplanets have the potential to capture dark matter, and, if captured in significant amounts, this dark matter may form a black hole within an exoplanet’s core. Such processes could lead to notable heating effects or even the destruction of the exoplanet.

6. Old neutron stars as a new probe of relic neutrinos and sterile neutrino dark matter

We study the kinetic cooling (heating) of old neutron stars due to coherent scattering with relic neutrinos (sterile neutrino dark matter) via Standard Model neutral-current interactions. We take into account several important physical effects, such as gravitational clustering, coherent enhancement, neutron degeneracy, Pauli blocking, and weak potential. We find that the anomalous cooling of...

33. A comprehensive analysis of supernova neutrino-dark matter interactions

Dr Deepak Sathyan

We present a comprehensive analysis of nonstandard neutrino interactions with the dark sector in an effective field theory (EFT) framework, considering exact analytic formulae for the differential scattering cross sections of neutrinos with scalar, fermionic, and vector dark matter (DM) for dark sector models with mediators of different spins. We then implement the full catalog of constraints...

1. Cosmic Ray Boosted Dark Matter at IceCube

Cosmic ray (CR) upscattering of dark matter is one of the most straightforward mechanisms to accelerate ambient dark matter, making it detectable at high threshold, large volume experiments. In this work, we revisit CR upscattered dark matter signals at the IceCube detector, considering both proton and electron scattering, in the former case including both quasielastic and deep inelastic...
