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…

Cosmological evolution of dark matter subhaloes under tidal stripping by growing Milky Way-like galaxies
Yudai Kazuno, Masao Mori, Yuka Kaneda +1
We present the findings of a comprehensive and detailed analysis of merger tree data from ultra-high-resolution cosmological -body simulations. The analysis, conducted with a pa…
