Dark Matter Heating of Compact Stars Beyond Capture: A Relativistic Framework for Energy Deposition by Particle Beams
Jaime Hoefken Zink, Shihwen Hor, Maura E. Ramirez-Quezada
Compact astrophysical objects, such as neutron stars and white dwarfs, can act as detectors of energetic particle fluxes originating from astrophysical accelerators. While most exi…
Beyond the Daisy Chain: Running and the 3D EFT View of Supercooled Phase Transitions
Martin Christiansen, Eric Madge, Cristina Puchades-Ibáñez +2
Pulsar timing arrays have recently observed a stochastic gravitational wave background at nano-Hertz frequencies. This raises the question whether the signal can be of primordial o…
Single pion resonant production in BSM scenarios: cross sections and amplitudes
Jaime Hoefken Zink, Maura E. Ramirez-Quezada
We present a comprehensive theoretical framework describing single pion resonant production through inelastic dark fermion-nucleon interactions mediated by resonances in the GeV-sc…
Insights on the Scale of Leptogenesis from Neutrino Masses and Neutrinoless Double-Beta Decay
Alessandro Granelli, Koichi Hamaguchi, Maura E. Ramirez-Quezada +3
We revisit the thermal leptogenesis scenario in the type-I seesaw framework featuring three heavy Majorana neutrinos with a hierarchical mass spectrum. We focus on low energy obser…
Dark Matter Interactions in White Dwarfs: A Multi-Energy Approach to Capture Mechanisms
Jaime Hoefken Zink, Shihwen Hor, Maura E. Ramirez-Quezada
White dwarfs offer a compelling avenue for probing interactions of dark matter particles, particularly in the challenging sub-GeV mass regime. The constraints derived from these ce…
Vortex Creep Heating vs. Dark Matter Heating in Neutron Stars
Motoko Fujiwara, Koichi Hamaguchi, Natsumi Nagata +1
Dark matter particles captured in neutron stars deposit their energy as heat. This DM heating effect can be observed only if it dominates over other internal heating effects in NSs…
