AXIS Could Have Accessed Dark Matter Decays
Joshua W. Foster, Inci Karaaslan, Gordan Krnjaic +1
The Advanced X-ray Imaging Satellite (AXIS) was a mission concept designed to improve upon the sensitivity and spatial resolution of the Chandra X-ray Observatory and XMM-Newton. A…
Correlated signals of ultralight scalar dark matter in pulsar timing
Joshua W. Foster, Kimberly K. Boddy, Jeff A. Dror +5
Pulsar timing arrays (PTAs) are sensitive to ultralight dark matter (ULDM) in the - mass range, with existing datasets already probing otherwise op…
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…
Inhomogeneous Energy Injection in the 21-cm Power Spectrum: Sensitivity to Dark Matter Decay
Yitian Sun, Joshua W. Foster, Hongwan Liu +2
The 21-cm signal provides a novel avenue to measure the thermal state of the universe during cosmic dawn and reionization (redshifts ), and thus to probe energy injecti…
Stochastic Gravitational Waves from Early Structure Formation
Nicolas Fernandez, Joshua W. Foster, Benjamin Lillard +1
Early matter-dominated eras (EMDEs) are a natural feature arising in many models of the early universe and can generate a stochastic gravitational wave background (SGWB) during the…
The statistics and sensitivity of axion wind detection with the homogeneous precession domain of superfluid helium-3
Joshua W. Foster, Christina Gao, William Halperin +5
The homogeneous precession domain (HPD) of superfluid He has recently been identified as a detection medium which might provide sensitivity to the axion-nucleon coupling $g_{…
Electromagnetic modeling and science reach of DMRadio-m
DMRadio Collaboration, A. AlShirawi, V. Ankel +45
DMRadio-m is an experiment that is designed to be sensitive to KSVZ and DFSZ QCD axion models in the 10--200\,MHz (41 neV -- 0.83 eV/) range. The experiment uses…
Projected Sensitivity of DMRadio-m: A Search for the QCD Axion Below eV
DMRadio Collaboration, L. Brouwer, S. Chaudhuri +31
The QCD axion is one of the most compelling candidates to explain the dark matter abundance of the universe. With its extremely small mass (), axion dark ma…
