We estimate the conventional astrophysical emission from dwarf spheroidal satellite galaxies (dSphs) of the Milky Way, focusing on millisecond pulsars (MSPs), and evaluate the potential for confusion with dark matter (DM) annihilation signatures at GeV energies. In low-density stellar environments, such as dSphs, the abundance of MSPs is expected to be proportional to stellar mass. Accordingly, we construct the $\gamma$-ray luminosity function of MSPs in the Milky Way disk, where $>90…

Millisecond Pulsar Origin of the Galactic Center Excess and Extended Gamma-Ray Emission from Andromeda: A Closer Look
A new measurement of a spatially extended gamma-ray signal from the center of the Andromeda galaxy (M31) has recently been published by the Fermi-LAT collaboration, reporting that the emission
Millisecond pulsars modify the radio-star-formation-rate correlation in quiescent galaxies
The observed correlation between the far-infrared and radio luminosities of galaxies illustrates the close connection between star formation and cosmic-ray production. Intriguingly, recent gamma-ray
Bayesian model comparison and analysis of the Galactic disc population of gamma-ray millisecond pulsars
Pulsed emission from almost one hundred millisecond pulsars (MSPs) has been detected in γ-rays by the Fermi Large-Area Telescope. The global properties of this population remain relatively
The Fermi-LAT GeV excess as a tracer of stellar mass in the Galactic bulge
An anomalous emission component at energies of a few gigaelectronvolts and located towards the inner Galaxy is present in the Fermi-LAT data. At present, the two most promising explanations are the
Cherenkov Telescope Array sensitivity to branon dark matter models
In the absence of a clear hint of dark matter (DM) signals in the GeV regime so far, heavy, $\mathcal{O}$(TeV) DM candidates are gradually earning more and more attention within the community. Among
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
Classification of gamma-ray targets for velocity-dependent and subhalo-boosted dark-matter annihilation
. Gamma-ray observations have long been used to constrain the properties of dark matter (DM), with a strong focus on weakly interacting massive particles annihilating through velocity-independent
Robust method for treating astrophysical mismodeling in dark matter annihilation searches of dwarf spheroidal galaxies
Fermi-LAT observations have strongly constrained dark matter annihilation through the joint-likelihood analysis of dwarf spheroidal galaxies (dSphs). These constraints are expected to be robust
Gamma-ray and synchrotron radiation from dark matter annihilations in ultra-faint dwarf galaxies
The very large (100–1000) mass-to-light ratio applicable to the ultra-faint dwarf galaxies (UFDs) implies a high concentration of dark matter, thus rendering them ideal theatres for indirect
Search for dark matter signals towards a selection of recently detected DES dwarf galaxy satellites of the Milky Way with H.E.S.S.
Dwarf spheroidal galaxy satellites of the Milky Way are prime targets for indirect detection of dark matter with gamma rays due to their proximity, high dark matter content and absence of non-thermal


The Gamma-Ray Luminosity Function of Millisecond Pulsars and Implications for the GeV Excess
It has been proposed that a large population of unresolved millisecond pulsars (MSPs) could potentially account for the excess of GeV-scale gamma-rays observed from the region surrounding the
Beacons In the Dark: Using Novae and Supernovae to Detect Dwarf Galaxies in the Local Universe
We propose that luminous transients, including novae and supernovae, can be used to detect the faintest galaxies in the universe. Beyond a few Mpc, dwarf galaxies with stellar masses $<10^6
Recent detections of the starburst galaxies M82 and NGC 253 by gamma-ray telescopes suggest that galaxies rapidly forming massive stars are more luminous at gamma-ray energies compared to their
Strong Support for the Millisecond Pulsar Origin of the Galactic Center GeV Excess.
It is argued that other extragalactic or Galactic sources, a mismodeling of Galactic diffuse emission, or the thick-disk population of pulsars are unlikely to account for this observation of clear excess emission in the Inner Galaxy.
The Gamma-Ray Pulsar Population of Globular Clusters: Implications for the GeV Excess
It has been suggested that the GeV excess, observed from the region surrounding the Galactic Center, might originate from a population of millisecond pulsars that formed in globular clusters. With
Millisecond pulsars cannot account for the inner Galaxy’s GeV excess
Using data from the Fermi Gamma-Ray Space Telescope, a spatially extended component of gamma rays has been identified from the direction of the Galactic center, peaking at energies of ∼2–3  GeV. More

We estimate the contribution of Galactic pulsars, both ordinary and millisecond pulsars (MSPs), to the high-energy ( > 100 MeV) γ−ray background. We pay particular attention to the high-latitude part
Dwarf galaxy annihilation and decay emission profiles for dark matter experiments
Gamma-ray searches for dark matter annihilation and decay in dwarf galaxies rely on an understanding of the dark matter density profiles of these systems. Conversely, uncertainties in these density
