Population Syntheses of Millisecond Pulsars from the Galactic Disk and Bulge

“…We find that the simulation produces a population of MSPs from the GD that contributes only about 10% to GC and so cannot account for the GCE (see Figure 20). We agree that the group of MSPs that Fermi has detected has an average spectral shape that agrees very well with the GCE as presented by Gordon & Macías (2013). We also agree that if somewhat over a thousand of these Fermi MSPs would be placed at the GC that they would account for the spectral intensity of the GCE.…”

“…The Galactic Center (GC) has recently generated great interest as careful studies of the γ-ray emission suggest an excess (GCE) over the diffuse background from cosmic ray interactions. Various groups (Gordon & Macías 2013;Hooper et al 2013;Calore et al 2015b,a;Abazajian et al 2014) and recently the Fermi team (Ajello et al 2016) have obtained the spectrum of the GCE, suggesting its origin may come from dark matter annihilation of particles beyond those of the Standard Model. The GC would then be expected to have the largest density of nearby dark matter.…”

“…The GC would then be expected to have the largest density of nearby dark matter. We focus on the spectrum of the GCE obtained by Gordon & Macías (2013)(GM13) as it is made available in Appendix A of their study. They suggest that a mixture of tau particle τ + τ − and b quark b + b − annihilation is required to adequately fit the Fermi spectrum of the GCE from the decay of a dark matter (DM) particle with a mass between 20 to 60 GeV.…”

“…The γ-ray power spectrum of the Galactic Center Excess. The solid red dots with red (statistical) and black (systematic) error bars from Appendix A of Gordon & Macías (2013). The dashed blue curve is the average power spectrum of 39 MSPs in the 2PC after converting their fluxes from their estimated distances, placing them at the GC at 8.5 kpc, and multiplying the average by 1365 yielding a power spectrum E 2 dN/dE = 3.4 × 10 −7 E 2 · E −1.29 e −E/2.5 GeV · cm −2 · s −1 .…”
