Puzzling Outer-Density Profile of the Dark Matter Halo in the Andromeda Galaxy
Takanobu Kirihara, Yohei Miki, Masao Mori
The cold dark matter (CDM) cosmology, which is the standard theory of the structure formation in the universe, predicts that the outer density profile of dark matter halos decrease…
Relics of Galaxy Merging: Observational Predictions for a Wandering Massive Black Hole and Accompanying Star Cluster in the Halo of M31
Toshihiro Kawaguchi, Yuriko Saito, Yohei Miki +1
Galaxies and massive black holes (BHs) presumably grow via galactic merging events and subsequent BH coalescence. As a case study, we investigate the merging event between the Andr…
Hunting A Wandering Supermassive Black Hole in M31 Halo -- Hermitage of Black Hole
Yohei Miki, Masao Mori, Toshihiro Kawaguchi +1
In the hierarchical structure formation scenario, galaxies enlarge through multiple merging events with less massive galaxies. In addition, the Magorrian relation indicates that al…
