Frequency of the dark matter subhalo collisions and bifurcation sequence arising formation of dwarf galaxies
Koki Otaki, Masao Mori
The cold dark matter (CDM) model predicts galaxies have 100 times more dark matter mass than stars. Nevertheless, recent observations report the existence of dark-matter-deficient…
Destruction of the central black hole gas reservoir through head-on galaxy collisions
Yohei Miki, Masao Mori, Toshihiro Kawaguchi
A massive black hole exists in almost every galaxy. They occasionally radiate a vast amount of light by releasing gravitational energy of accreting gas, with a cumulative active pe…
Discrimination of heavy elements originating from Pop III stars in z = 3 intergalactic medium
Takanobu Kirihara, Kenji Hasegawa, Masayuki Umemura +2
We investigate the distribution of metals in the cosmological volume at , in particular, provided by massive population III (Pop III) stars using a cosmological -body si…
Stellar Stream and Halo Structure in the Andromeda Galaxy From a Subaru/Hyper Suprime-Cam Survey
Yutaka Komiyama, Masashi Chiba, Mikito Tanaka +13
We present wide and deep photometry of the northwest part of the halo of the Andromeda galaxy (M31) using Hyper Suprime-Cam on the Subaru Telescope. The survey covers 9.2 deg…
The nature of the progenitor of the M31 North-western stream: globular clusters as milestones of its orbit
Takanobu Kirihara, Yohei Miki, Masao Mori
We examine the nature, possible orbits and physical properties of the progenitor of the North-western stellar stream (NWS) in the halo of the Andromeda galaxy (M31). The progenitor…
Systematic Identification of LAEs for Visible Exploration and Reionization Research Using Subaru HSC (SILVERRUSH). I. Program Strategy and Clustering Properties of ~2,000 Lya Emitters at z=6-7 over the 0.3-0.5 Gpc Survey Area
Masami Ouchi, Yuichi Harikane, Takatoshi Shibuya +17
We present the SILVERRUSH program strategy and clustering properties investigated with Ly emitters at and found in the early data of the Hyper Suprime…
