$J$-factor estimation of Draco, Sculptor and Ursa Minor dwarf spheroidal galaxies with the member/foreground mixture model

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shun-ichi Horigome, Kohei Hayashi, Masahiro Ibe, Miho N. Ishigaki, Shigeki Matsumoto | Summary: Dwarf spheroidal galaxies (dSphs) are promising targets of indirect detection experiments searching for dark matter (DM) at present universe. Toward robust prediction for the amount of signal flux originating in DM annihilation inside dSphs, […]

Competition between magnetic order and charge localization in Na$_2$IrO$_3$ thin crystal devices

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Josue Rodriguez, Gilbert Lopez, Samantha Crouch, Nicholas P. Breznay, Robert Kealhofer | Summary: Spin orbit assisted Mott insulators such as sodium iridate (Na$_2$IrO$_3$) have been an important subject of study in the recent years. In these materials, the interplay of electronic correlations, spin-orbit coupling, crystal field effects […]
