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…

Was There a 3.5 keV Line?

Christopher Dessert, Joshua W. Foster, Yujin Park +1

The 3.5 keV line is a purported emission line observed in galaxies, galaxy clusters, and the Milky Way whose origin is inconsistent with known atomic transitions and has previously…

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…

A deep search for decaying dark matter with XMM-Newton blank-sky observations

Joshua W. Foster, Marius Kongsore, Christopher Dessert +4

Sterile neutrinos with masses in the keV range are well-motivated extensions to the Standard Model that could explain the observed neutrino masses while also making up the dark mat…
