Sensitivity of JWST to eV-Scale Decaying Axion Dark Matter
Sandip Roy, Carlos Blanco, Christopher Dessert +2
The recently-launched James Webb Space Telescope (JWST) can resolve eV-scale emission lines arising from dark matter (DM) decay. We forecast the end-of-mission sensitivity to the d…
Dissipative Dark Substructure: The Consequences of Atomic Dark Matter on Milky Way Analog Subhalos
Caleb Gemmell, Sandip Roy, Xuejian Shen +4
Using cosmological hydrodynamical zoom-in simulations, we explore the properties of subhalos in Milky Way analogs that contain a sub-component of Atomic Dark Matter (ADM). ADM diff…
Simulating Atomic Dark Matter in Milky Way Analogues
Sandip Roy, Xuejian Shen, Mariangela Lisanti +3
Dark sector theories naturally lead to multi-component scenarios for dark matter where a sub-component can dissipate energy through self-interactions, allowing it to efficiently co…
