Three-body capture, ejection, and the demographics of bound objects in binary systems
Benjamin V. Lehmann, Olivia G. Ross, Ava Webber +1
We study the capture of light objects of arbitrary velocity by binary systems. Extending results for the capture of comets in the solar system, we develop a simple geometric charac…
Model-independent discovery prospects for primordial black holes at LIGO
Benjamin V. Lehmann, Stefano Profumo, Jackson Yant
Primordial black holes may encode the conditions of the early universe, and may even constitute a significant fraction of cosmological dark matter. Their existence has yet to be es…
Cosmological implications of the KOTO excess
Wolfgang Altmannshofer, Benjamin V. Lehmann, Stefano Profumo
The KOTO experiment has reported an excess of events above the Standard Model prediction, in tension with the Grossman-Nir (GN) bound. The GN bound heavily constr…
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…
