The Andromeda Gamma-Ray Excess: Background Systematics of the Millisecond Pulsars and Dark Matter Interpretations
Fabian Zimmer, Oscar Macias, Shin'ichiro Ando +2
Since the discovery of an excess in gamma rays in the direction of M31, its cause has been unclear. Published interpretations focus on a dark matter or stellar related origin. Stud…
Decaying dark matter in dwarf spheroidal galaxies: Prospects for X-ray and gamma-ray telescopes
Shin'ichiro Ando, Suvendu K. Barik, Zhuoran Feng +12
Dwarf spheroidal galaxies are dark matter dominated systems, and as such, ideal for indirect dark matter searches. If dark matter decays into high-energy photons in the dwarf galax…
Searches for sterile neutrinos and axionlike particles from the Galactic halo with eROSITA
Ariane Dekker, Ebo Peerbooms, Fabian Zimmer +2
Dark matter might be made of "warm" particles, such as sterile neutrinos in the keV mass range, which can decay into photons through mixing and are consequently detectable by X-ray…
