Dark Matter Weather: Probing Sub-GeV Interactions with Earth-Shielding Modulation
Tetiana Kozynets, Rebecca Leane, Juri Smirnov
Daily modulation from Earth shielding provides a powerful search handle for sub-GeV dark matter (DM) in low-threshold experiments. We use this effect as a probe of interaction stru…
Complementary Planetary Spectroscopy Probes of Dark Matter
Carlos Blanco, Rebecca K. Leane, Marianne Moore +1
We investigate dark matter (DM) interactions via spectroscopic signatures of energy injection in planetary environments. We develop a general framework to account for how DM energy…
Search for Dark Matter Induced Airglow in Planetary Atmospheres
Carlos Blanco, Rebecca K. Leane, Marianne Moore +1
We point out that dark matter can illuminate planetary skies via ultraviolet airglow. Dark matter annihilation products can excite molecular hydrogen, which then deexcites to produ…
Sub-GeV Dark Matter Detection with Dark Rates in Liquid Scintillators
Lillian Santos-Olmsted, Rebecca K. Leane, Carlos Blanco +1
It was recently shown that standard sub-GeV dark matter candidates can be effectively probed by large neutrino observatories via annual modulation of the total photomultiplier hit…
Search for Dark Matter Annihilation and Decay with H Line Emission
Rebecca K. Leane
I present a new indirect search for dark matter (DM) using Hydrogen- (H) recombination emission. DM annihilation or decay products can ionize neutral gas; subsequent recombin…
Sub-GeV Dark Matter Direct Detection with Neutrino Observatories
Rebecca K. Leane, John F. Beacom
We present a new technique for sub-GeV dark matter (DM) searches and a new use of neutrino observatories. DM-electron scattering in an observatory can excite or ionize target molec…
