An Excited Dark Matter Solution to the MeV Galactic Center Excesses
Shyam Balaji, Damon Cleaver, Pedro De la Torre Luque
Recent COMPTEL data analysis reveals a 2 MeV continuum excess whose spatial distribution closely matches the long-standing 511 keV line observed by INTEGRAL/SPI, indicating…

Dark Matter in X-rays: Revised XMM-Newton Limits and New Constraints from eROSITA
Shyam Balaji, Damon Cleaver, Pedro De la Torre Luque +1
We investigate two classes of dark matter (DM) candidates, sub-GeV particles and primordial black holes (PBHs), that can inject low-energy electrons and positrons into the Milky Wa…

Listening for ultra-heavy dark matter with underwater acoustic detectors
Damon Cleaver, Christopher McCabe, Ciaran A. J. O'Hare
Ultra-heavy dark matter candidates evade traditional direct detection experiments due to their low particle flux. We explore the potential of large underwater acoustic arrays, orig…
