The Galactic dwarf spheroidal (dSph) galaxies are excellent laboratories to shed light on fundamental properties of dark matter.
In particular, the dSphs are promising targets for the indirect searches for particle dark matter.
In order to set robust constraints on properties of dark matter particles, revealing dark matter distributions in these galaxies is of crucial importance.
However,...

Structure of dark matter halo is hierarchical. Among them, small-scale structures in dark matter halo (so-called subhalos,) can enhance dark matter annihilation signals. It is necessary to quantify boost factors by those subhalos to derive the property of dark matter with current/future gamma-ray observations. In order to derive the subhalo boost factors, calculations of halo structure...

Dark matter in cosmic structures is expected to produce signals
originated from its particle physics nature, among which the electromagnetic
emission represents a relevant opportunity, whose intensity is directly linked
to the amount of dark matter in galaxies and clusters. On the other hand, this
emission is very faint, thus contributing only at the unresolved level. These
unresolved...

Recently, there appears lots of papers on the possibility of light Dark Matter (DM) in MeV and sub-GeV scale. Until now, only INTEGRAL and COMPTEL provided experimental data of 511keV of galactic center, and two spectra of g
Galactic Diffuse MeV gammas (GDMG) and Cosmic Background MeV gammas (CBMG) for indirect detection of light DMs. However except 511keV, those two spectra included large...

The General Antiparticle Spectrometer (GAPS) is a balloon-borne experiment which aims to survey low-energy cosmic-ray antinuclei. A novel detection concept that utilizes the physics of exotic atoms allows GAPS to realize a large sensitive area, a low energy threshold, and a high identification capability for antinuclei. The primary goal is to search for antideuterons in the energy region <0.25...
