Young Pulsars and the Galactic Center GeV Gamma-ray Excess

  title={Young Pulsars and the Galactic Center GeV Gamma-ray Excess},

  journal={arXiv: High Energy Astrophysical Phenomena},
Studies of Fermi data indicate an excess of GeV gamma rays around the Galactic center (GC), possibly due to dark matter. We show that young gamma-ray pulsars can yield a similar signal. First, a high concentration of GC supernovae naturally leads to a population of kicked pulsars symmetric about the GC. Second, while very-young pulsars with soft spectra reside near the Galactic plane, pulsars with spectra that have hardened with age accumulate at larger angles. This combination, including…

Prospects for Pulsar Studies at MeV Energies

Enabled by the Fermi Large Area Telescope, we now know young and recycled pulsars fill the gamma-ray sky, and we are beginning to understand their emission mechanism and their distribution throughout

Galactic bulge preferred over dark matter for the Galactic centre gamma-ray excess

An anomalous gamma-ray excess emission has been found in the Fermi Large Area Telescope data1 covering the centre of the Galaxy2,3. Several theories have been proposed for this ‘Galactic centre

A Tale of Two Pulsars and the Origin of TeV Gamma Rays from the Galactic Center

The Galactic Center (GC) has been long known to host gamma-ray emission detected to >10 TeV. HESS data now points to two plausible origins: the supermassive black hole (perhaps with >PeV cosmic rays

The Fermi Galactic Center GeV Excess and Implications for Dark Matter

The region around the Galactic Center (GC) is now well established to be brighter at energies of a few GeV than what is expected from conventional models of diffuse gamma-ray emission and catalogs of

Consistency between the luminosity function of resolved millisecond pulsars and the galactic center excess

Fermi Large Area Telescope data reveal an excess of GeV gamma rays from the direction of the Galactic Center and bulge. Several explanations have been proposed for this excess including an unresolved

Astrophysical contributions to the Fermi Galactic Centre GeV excess.

An excess of GeV gamma rays above the expected astrophysical background has been detected in the region of the sky towards the centre of the Milky Way using observations from the Fermi Large Area

Low mass X-ray binaries in the Inner Galaxy: implications for millisecond pulsars and the GeV excess

If millisecond pulsars (MSPs) are responsible for the excess gamma-ray emission observed from the region surrounding the Galactic Center, the same region should also contain a large population of

Strong evidence that the galactic bulge is shining in gamma rays

There is growing evidence that the Galactic Center Excess identified in the Fermi-LAT gamma-ray data arises from a population of faint astrophysical sources. We provide compelling supporting evidence

Investigating the uniformity of the excess gamma rays towards the galactic center region

We perform a composite likelihood analysis of subdivided regions within the central 26° × 20° of the Milky Way, with the aim of characterizing the spectrum of the gamma-ray galactic center excess in

Return of the templates: Revisiting the Galactic Center excess with multimessenger observations

The Galactic center excess (GCE) remains one of the most intriguing discoveries from the Fermi Large Area Telescope (LAT) observations. We revisit the characteristics of the GCE by first producing a
