Cross Correlation of the Extragalactic Gamma-ray Background with Thermal Sunyaev-Zel'dovich Effect in the Cosmic Microwave Background
Masato Shirasaki, Oscar Macias, Shin'ichiro Ando +2
Cosmic rays in galaxy clusters are unique probes of energetic processes operating with large-scale structures in the Universe. Precise measurements of cosmic rays in galaxy cluster…
The Abundance and Structure of Subhaloes near the Free Streaming Scale and Their Impact on Indirect Dark Matter Searches
Tomoaki Ishiyama, Shin'ichiro Ando
The free streaming motion of dark matter particles imprints a cutoff in the matter power spectrum and set the scale of the smallest dark matter halo. Recent cosmological -body s…
Constraining dark matter annihilation with HSC Low Surface Brightness Galaxies
Daiki Hashimoto, Oscar Macias, Atsushi J. Nishizawa +4
Searches for dark matter annihilation signals have been carried out in a number of target regions such as the Galactic Center and Milky Way dwarf spheroidal galaxies (dSphs), among…
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…
Halo Substructure Boosts to the Signatures of Dark Matter Annihilation
Shin'ichiro Ando, Tomoaki Ishiyama, Nagisa Hiroshima
The presence of dark matter substructure will boost the signatures of dark matter annihilation. We review recent progress on estimates of this subhalo boost factor---a ratio of the…
