Time-delayed gamma-ray signatures of heavy axions from core-collapse supernovae
Joshua N. Benabou, Claudio Andrea Manzari, Yujin Park +3
Heavy axions that couple to both quantum electrodynamics and quantum chromodynamics with masses on the order of MeV - GeV and high-scale decay constants in excess of G…
Supernova axions convert to gamma-rays in magnetic fields of progenitor stars
Claudio Andrea Manzari, Yujin Park, Benjamin R. Safdi +1
It has long been established that axions could have been produced within the nascent proto-neutron-star formed following the type II supernova SN1987A, escaped the star due to thei…
Signatures of Primordial Energy Injection from Axion Strings
Joshua N. Benabou, Malte Buschmann, Soubhik Kumar +2
Axion strings are horizon-size topological defects that may be produced in the early Universe. Ultra-light axion-like particles may form strings that persist to temperatures below…
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…
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…
