Statistics of Daily Modulation in Dark Matter Direct Detection Experiments
Carlos Blanco, Joshua W. Foster, Yonatan Kahn +1
The time-dependent modulation of the event rate in dark matter direct detection experiments, arising from the motion of the Earth with respect to the Galactic rest frame, is a dist…

Constraining inhomogeneous energy injection from annihilating dark matter and primordial black holes with 21-cm cosmology
Yitian Sun, Joshua W. Foster, Julian B. Muñoz
The cosmic dawn 21-cm signal is a highly sensitive probe of any process which injects energy into the intergalactic medium, enabling novel searches for anomalous energy injection b…

dSphobic Dark Matter
Asher Berlin, Joshua W. Foster, Dan Hooper +1
We present a mechanism that allows thermal relic dark matter to annihilate efficiently in the Galactic Halo and in galaxy clusters, but not in the lower-velocity environments of dw…
