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…
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…
The Inflated Chern-Simons Number in Spectator Chromo-Natural Inflation
Hengameh Bagherian, Matthew Reece, Weishuang Linda Xu
The chromo-natural inflation (CNI) scenario predicts a potentially detectable chiral gravitational wave signal, generated by a Chern-Simons coupling between a rolling scalar axion…
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…
The Physics of Light Relics
Cora Dvorkin, Joel Meyers, Peter Adshead +19
Many well-motivated extensions of the Standard Model predict the existence of new light species that may have been produced in the early universe. Prominent examples include axions…
Dark Matter Physics from the CMB-S4 Experiment
Cora Dvorkin, Renée Hlozek, Rui An +10
The nature of dark matter is one of the major puzzles of fundamental physics, integral to the understanding of our universe across almost every epoch. The search for dark matter ta…
