Tunneling and tidal stripping in multifield ultralight dark matter halos
Benjamin V. Lehmann, Jackie Lodman, Thomas Steingasser
Tidal stripping is a key feature of the evolution of dark matter (DM) halos, and has major implications for the population of low-mass galaxies. In the case of ultralight DM, tidal…
Fast and Fewrious: Stochastic binary perturbations from fast compact objects
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
Massive compact objects soften binaries. This process has been used for decades to constrain the population of such objects, particularly as a component of dark matter (DM). The ef…
Dancing with invisible partners: Three-body exchanges with primordial black holes
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
The abundance of massive primordial black holes has historically been constrained by dynamical probes. Since these objects can participate in hard few-body scattering processes, th…
Close encounters of the primordial kind: a new observable for primordial black holes as dark matter
Tung X. Tran, Sarah R. Geller, Benjamin V. Lehmann +1
Primordial black holes (PBHs) remain a viable dark matter candidate in the asteroid-mass range. We point out that in this scenario, the PBH abundance would be large enough for at l…
Kinetic recoupling of dark matter
Benjamin V. Lehmann, Logan Morrison, Stefano Profumo +1
We study the possibility that dark matter re-enters kinetic equilibrium with a radiation bath after kinetic decoupling, a scenario we dub kinetic recoupling. This naturally occurs,…
