Cosmology and prospects for sub-MeV dark matter in electron recoil experiments
Benjamin V. Lehmann, Stefano Profumo
Dark matter is poorly constrained by direct detection experiments at masses below 1 MeV. This is an important target for the next generation of experiments, and several methods hav…

Direct detection of primordial black hole relics as dark matter
Benjamin V. Lehmann, Christian Johnson, Stefano Profumo +1
If dark matter is composed of primordial black holes, such black holes can span an enormous range of masses. A variety of observational constraints exist on massive black holes, an…

Connecting direct and indirect detection with a dark spike in the cosmic-ray electron spectrum
Adam Coogan, Benjamin V. Lehmann, Stefano Profumo
Multiple space-borne cosmic ray detectors have detected line-like features in the electron and positron spectra. Most recently, the DAMPE collaboration reported the existence of su…
