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…

Discovery prospects of dwarf spheroidal galaxies for indirect dark matter searches
Shin'ichiro Ando, Bradley J. Kavanagh, Oscar Macias +12
We study the prospects for the Large Synoptic Survey Telescope (LSST) to find new dwarf spheroidal galaxies in the Milky Way. Adopting models of Milky-Way halo substructure and phe…
