Resonant axion and dark photon production in magnetic white dwarfs
Nirmalya Brahma, Ella Iles, Hugo Schérer +1
Using magnetic white dwarfs as a case study, we show that the emission of sub-MeV bosons from stellar plasmas can be substantially modified in the presence of a magnetic field. In…

Photon-Dark Photon Conversion with Multiple Level Crossings
Nirmalya Brahma, Asher Berlin, Katelin Schutz
Dark photons can oscillate into Standard Model (SM) photons via kinetic mixing. The conversion probability depends sensitively on properties of the ambient background, such as the…

Resonant Pseudo-Dirac Dark Matter as a Sub-GeV Thermal Target
Nirmalya Brahma, Saniya Heeba, Katelin Schutz
Dark matter (DM) could be a pseudo-Dirac thermal relic with a small mass splitting that is coupled off-diagonally to a kinetically mixed dark photon. This model, particularly in th…
