The Characterization of the Gamma-Ray Signal from the Central Milky Way: A Compelling Case for Annihilating Dark Matter
Tansu Daylan, Douglas P. Finkbeiner, Dan Hooper +4
Past studies have identified a spatially extended excess of 1-3 GeV gamma rays from the region surrounding the Galactic Center, consistent with the emission expected from ann…
Closing in on the Fermi Line with a New Observation Strategy
Christoph Weniger, Meng Su, Douglas P. Finkbeiner +2
Evidence for a spectral line in the inner Galaxy has caused a great deal of excitement over the last year, mainly because of its interpretation as a possible dark matter signal. Th…
Is the 130 GeV Line Real? A Search for Systematics in the Fermi-LAT Data
Douglas P. Finkbeiner, Meng Su, Christoph Weniger
Our recent claims of a Galactic center feature in Fermi-LAT data at approximately 130 GeV have prompted an avalanche of papers proposing explanations ranging from dark matter annih…
Double Gamma-ray Lines from Unassociated Fermi-LAT Sources
Meng Su, Douglas P. Finkbeiner
Gamma ray emission from dark matter subhalos in the Milky Way has long been sought as a sign of dark matter particle annihilation. So far, searches for gamma-ray continuum from sub…
Strong Evidence for Gamma-ray Line Emission from the Inner Galaxy
Meng Su, Douglas P. Finkbeiner
Using 3.7 years of \Fermi-LAT data, we examine the diffuse 80-200 GeV emission in the inner Galaxy and find a resolved gamma-ray feature at GeV. We model the spatial…
Evidence for Gamma-ray Jets in the Milky Way
Meng Su, Douglas P. Finkbeiner
Although accretion onto supermassive black holes in other galaxies is seen to produce powerful jets in X-ray and radio, no convincing detection has ever been made of a kpc-scale je…
