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…
A New Concept of Transonic Galactic Outflows in a Cold Dark Matter Halo with a Central Super-Massive Black Hole
Asuka Igarashi, Masao Mori, Shin-ya Nitta
We study fundamental properties of isothermal, steady and spherically symmetric galactic outflow in the gravitational potential of a cold dark matter halo and a central super-massi…
Transonic Galactic Outflows and Their Influences to the Chemical Evolution of Galaxies and Intergalactic Space
Asuka Igarashi, Masao Mori, Shin-ya Nitta
We have categorized possible transonic solutions of galactic outflows in the gravitational potential of DMH and SMBH using the isothermal, spherically symmetric and steady model. W…
Transonic galactic outflows in a dark matter halo with a central black hole and its application to the Sombrero galaxy
Asuka Igarashi, Masao Mori, Shin-ya Nitta
We have classified possible transonic solutions of galactic outflows in the gravitational potential of the dark matter halo (DMH) and super massive black hole (SMBH) under the assu…
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…
