Warm Dark Matter Constraints Using Milky-Way Satellite Observations and Subhalo Evolution Modeling
Ariane Dekker, Shin'ichiro Ando, Camila A. Correa +1
Warm dark matter (WDM) can potentially explain small-scale observations that currently challenge the cold dark matter (CDM) model, as warm particles suppress structure formation du…
Virial halo mass function in the cosmology
Masato Shirasaki, Tomoaki Ishiyama, Shin'ichiro Ando
We study halo mass functions with high-resolution -body simulations under a CDM cosmology. Our simulations adopt the cosmological model that is consistent with recent measure…
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…
Sommerfeld-enhanced dark matter searches with dwarf spheroidal galaxies
Shin'ichiro Ando, Koji Ishiwata
We study observable signals from dark matter that self-annihilates via the Sommerfeld effect in dwarf spheroidal galaxies (dSphs). Since the effect of the Sommerfeld enhancement de…
Cherenkov Telescope Array sensitivity to the putative millisecond pulsar population responsible for the Galactic center excess
Oscar Macias, Harm van Leijen, Deheng Song +3
The leading explanation of the Galactic center -ray excess is the extended emission from a unresolved population of millisecond pulsars (MSPs) in the Galactic b…
