Formation of Parallel Stellar Streams through Encounters with Dark Matter Subhalos and Intermediate-Mass Black Holes
Yuka Kaneda, Masao Mori, Yohei Miki +2
Dark matter subhalos and intermediate-mass black holes wandering in the Milky Way and the Andromeda galaxy are difficult to directly detect through electromagnetic observations, ye…

The Characteristic Mass and Energy Conversion Efficiency in the Cusp-Core Transition of Dark Matter Haloes: Implications for Scaling Relations and Supernova feedbacks
Michi Shinozaki, Masao Mori, Yuka Kaneda +1
Galaxies in the nearby Universe, particularly dwarf systems, exhibit inner mass profiles of dark matter haloes that systematically depart from canonical cold dark matter expectatio…

Cusp-to-Core Transition of Dark Matter Halos across Galaxy Mass Scales
Kohei Hayashi, Yuka Kaneda, Masao Mori +1
We investigate the diversity of dark matter (DM) density profiles in a large sample of late-type galaxies from the SPARC database, with the goal of testing whether a cusp-to-core t…
