Comparing the Galactic Bulge and Galactic Disk Millisecond Pulsars
Harrison Ploeg, Chris Gordon, Roland Crocker +1
The Galactic Center Excess (GCE) is an extended gamma-ray source in the central region of the Galaxy found in Fermi Large Area Telescope (Fermi-LAT) data. One of the leading explan…
Prospects for Heavy WIMP Dark Matter with CTA: the Wino and Higgsino
Lucia Rinchiuso, Oscar Macias, Emmanuel Moulin +2
TeV-scale particles that couple to the standard model through the weak force represent a compelling class of dark matter candidates. The search for such Weakly Interacting Massive…
Green Bank and Effelsberg Radio Telescope Searches for Axion Dark Matter Conversion in Neutron Star Magnetospheres
Joshua W. Foster, Yonatan Kahn, Oscar Macias +6
Axion dark matter (DM) may convert to radio-frequency electromagnetic radiation in the strong magnetic fields around neutron stars. The radio signature of such a process would be a…
Strong constraints on thermal relic dark matter from Fermi-LAT observations of the Galactic Center
Kevork N. Abazajian, Shunsaku Horiuchi, Manoj Kaplinghat +2
The extended excess toward the Galactic Center (GC) in gamma rays inferred from Fermi-LAT observations has been interpreted as being due to dark matter (DM) annihilation. Here, we…
Foreground Mismodeling and the Point Source Explanation of the Fermi Galactic Center Excess
Malte Buschmann, Nicholas L. Rodd, Benjamin R. Safdi +4
The Fermi Large Area Telescope has observed an excess of ~GeV energy gamma rays from the center of the Milky Way, which may arise from near-thermal dark matter annihilation. Firmly…
