Bilayer graphene enables sub-MeV dark matter detection via electronic excitations with small exposure and sidereal modulation signatures.
Projects COSI and AMEGO-X sensitivities to sub-GeV DM in vector-scalar portals, finding COSI leading in some regions beyond CMB limits and AMEGO-X covering most continuum cases.
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.
New upper bounds on millicharged particles (masses 10-100 keV, charges down to 5e-13) from the AGB-to-HB star ratio in globular clusters, improving prior limits by up to two orders of magnitude.
