Asteroid-mass primordial black holes induce a Riemann tidal splitting of the 2P_{3/2} hydrogen state, turning the 9.9 GHz line into a ~2 GHz bandwidth gravitational spectral radio forest in H II regions with accretion-enhanced emission measure.

The nuclear star cluster around Sgr A* is the dominant source of gravitationally boosted dark matter in the Milky Way, with particles up to ~25,000 km/s that enhance sub-GeV detection prospects independently of the DM model.
For sub-GeV dark matter, the light and heavy mediator mass limits in direct detection are separated by up to three orders of magnitude in mediator mass, enabling precise sensitivity calculations for Si, Ge, and DAMIC-M targets.
Bilayer graphene enables sub-MeV dark matter detection via electronic excitations with small exposure and sidereal modulation signatures.
Super-Kamiokande data constrains the DM-electron scattering cross-section for leptophilic dark matter to ~4e-41 cm2 below 100 GeV, exceeding direct detection by over an order of magnitude.
A review summarizing current observational, experimental, and theoretical results on dark matter.
