The temperature of baryons at the end of the cosmic dark ages can be measured using the 21-cm hyperfine transition of neutral hydrogen. Any energy injection from the dark sector can potentially be constrained through these measurements. Exotic compact objects, such as PBHs, can alter the temperature by transferring heat to the gas through dynamical friction (DF). In this study, we compute the...
In this work, we investigate the potential of cosmic boosted strongly interacting dark matter (CBSIDM), which opens up the sub-GeV mass range for exploration. The boosted kinetic energy of CBSIDM enhances Earth’s ability to capture DM particles in this range, thereby extending the accessible mass range below 1 GeV and making direct detection signals observable. This also allows CBSIDM to...
The existence of relic neutrino background is a strong prediction of the Big Bang cosmology. But because of their extremely small kinetic energy today, the direct detection of relic neutrinos remains elusive. On the other hand, we know very little about the nature of dark matter. In this work, we propose to probe the cosmic neutrino background by using their resonant scattering with ultra...
