A Search for Dark Matter Lines at the Galactic Center with 14 Years of Fermi Data
Joshua W. Foster, Yujin Park, Benjamin R. Safdi +2
Dark matter (DM) in the Milky Way halo may annihilate or decay to photons, producing monochromatic gamma rays. We search for DM-induced spectral lines using 14 years of data from t…
Detecting axion dark matter beyond the magnetoquasistatic approximation
Joshua N. Benabou, Joshua W. Foster, Yonatan Kahn +2
A number of proposals have been put forward for detecting axion dark matter (DM) with grand unification scale decay constants that rely on the conversion of coherent DM axions to o…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
Dark Grand Unification in the Axiverse: Decaying Axion Dark Matter and Spontaneous Baryogenesis
Joshua W. Foster, Soubhik Kumar, Benjamin R. Safdi +1
The quantum chromodynamics axion with a decay constant near the Grand Unification (GUT) scale has an ultralight mass near a neV. We show, however, that axion-like particles with ma…
Higgsino Dark Matter Confronts 14 years of Fermi Gamma Ray Data
Christopher Dessert, Joshua W. Foster, Yujin Park +2
Thermal higgsino dark matter (DM), with mass around 1 TeV, is a well-motivated, minimal DM scenario that arises in supersymmetric extensions of the Standard Model. Higgsinos may na…
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…
