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…
Probing dark matter signals in neutrino telescopes through angular power spectrum
Ariane Dekker, Marco Chianese, Shin'ichiro Ando
The hypothesis of two different components in the high-energy neutrino flux observed with IceCube has been proposed to solve the tension among different data-sets and to account fo…
Probing heavy dark matter decays with multi-messenger astrophysical data
Koji Ishiwata, Oscar Macias, Shin'ichiro Ando +1
We set conservative constraints on decaying dark matter particles with masses spanning a very wide range ( GeV). For this we use multimessenger observations of cosmic…
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…
