Dynamical Heating from Dark Compact Objects and Axion Minihalos: Implications for the 21-cm Signal
Badal Bhalla, Aurora Ireland, Hongwan Liu +2
The temperature of baryons at the end of the cosmic dark ages can be inferred from observations of the 21-cm hyperfine transition in neutral hydrogen. Any energy injection from the…
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…
Supernova-Boosted Dark Matter at Large-Volume Neutrino Detectors
Badal Bhalla, Fazlollah Hajkarim, Doojin Kim +1
Core-collapse supernovae, among the universe's most energetic events, offer a novel window into the dark sector by potentially producing a flux of boosted dark matter (BDM). We exp…
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…
Exploring Dark Forces with Multimessenger Studies of Extreme Mass Ratio Inspirals
Badal Bhalla, Kuver Sinha, Tao Xu
The exploration of dark sector interactions via gravitational waves (GWs) from binary inspirals has been a subject of recent interest. We study dark forces using extreme mass ratio…
