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…
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…
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…
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…
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…
Dark Matter Halo Parameters from Overheated Exoplanets via Bayesian Hierarchical Inference
María Benito, Konstantin Karchev, Rebecca K. Leane +3
Dark Matter (DM) can become captured, deposit annihilation energy, and hence increase the heat flow in exoplanets and brown dwarfs. Detecting such a DM-induced heating in a populat…
Dark Branches of Immortal Stars at the Galactic Center
Isabelle John, Rebecca K. Leane, Tim Linden
We show that stars in the inner parsec of the Milky Way can be significantly affected by dark matter annihilation, producing population-level effects that are visible in a Hertzspr…
Optimal Celestial Bodies for Dark Matter Detection
Rebecca K. Leane, Joshua Tong
A wide variety of celestial bodies have been considered as dark matter detectors. Which stands the best chance of delivering the discovery of dark matter? Which is the most powerfu…
Dark Kinetic Heating of Exoplanets and Brown Dwarfs
Javier F. Acevedo, Rebecca K. Leane, Aidan J. Reilly
Dark kinetic heating of neutron stars has been previously studied as a promising dark matter detection avenue. Kinetic heating occurs when dark matter is sped up to relativistic sp…
Transmon Qubit Constraints on Dark Matter-Nucleon Scattering
Anirban Das, Noah Kurinsky, Rebecca K. Leane
We recently pointed out that power measurements of single quasiparticle devices can be used to detect dark matter. These devices have the lowest known energy thresholds, far surpas…
Search for Dark Matter Ionization on the Night Side of Jupiter with Cassini
Carlos Blanco, Rebecca K. Leane
We present a new search for dark matter using planetary atmospheres. We point out that annihilating dark matter in planets can produce ionizing radiation, which can lead to excess…
Detecting Dark Matter Induced Power in Quantum Devices
Anirban Das, Noah Kurinsky, Rebecca K. Leane
In the past few years, many mesoscale systems have been proposed as possible detectors of sub-GeV dark matter particles. In this work, we point out the feasibility of probing dark…
Dark Matter Scattering Constraints from Observations of Stars Surrounding Sgr A*
Isabelle John, Rebecca K. Leane, Tim Linden
High resolution infrared data has revealed several young stars in close proximity to Sgr A*. These stars may encounter extremely high dark matter densities. We examine scenarios wh…
Milky Way White Dwarfs as Sub-GeV to Multi-TeV Dark Matter Detectors
Javier F. Acevedo, Rebecca K. Leane, Lillian Santos-Olmsted
We show that Milky Way white dwarfs are excellent targets for dark matter (DM) detection. Using Fermi and H.E.S.S. Galactic center gamma-ray data, we investigate sensitivity to DM…
Dark Matter Capture in Celestial Objects: Treatment Across Kinematic and Interaction Regimes
Rebecca K. Leane, Juri Smirnov
Signatures of dark matter in celestial objects have become of increasing interest due to their powerful detection prospects. To test any of these signatures, the fundamental quanti…
Evaporation Barrier for Dark Matter in Celestial Bodies
Javier F. Acevedo, Rebecca K. Leane, Juri Smirnov
The minimum testable dark matter (DM) mass for almost all DM signatures in celestial bodies is determined by the rate at which DM evaporates. DM evaporation has previously been cal…
Dark Matter Induced Power in Quantum Devices
Anirban Das, Noah Kurinsky, Rebecca K. Leane
We point out that power measurements of single quasiparticle devices open a new avenue to detect dark matter (DM). The threshold of these devices is set by the Cooper pair binding…
