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…
Spitzer Observations of the North Ecliptic Pole
H. Nayyeri, N. Ghotbi, A. Cooray +19
We present a photometric catalog for Spitzer Space Telescope warm mission observations of the North Ecliptic Pole (NEP; centered at , $\rm Decl.=66^d33^m38^s…
New Spectral Evidence of an Unaccounted Component of the Near-infrared Extragalactic Background Light from the CIBER
Shuji Matsuura, Toshiaki Arai, James J. Bock +12
The Extragalactic Background Light (EBL) captures the total integrated emission from stars and galaxies throughout the cosmic history. The amplitude of the near-infrared EBL from s…
Growth of First Galaxies: Impacts of Star Formation and Stellar Feedback
Hidenobu Yajima, Kentaro Nagamine, Qirong Zhu +2
We present the results of cosmological hydrodynamic simulations with zoom-in initial conditions, and investigate the formation of the first galaxies and their evolution towards obs…
Dusty Gas Accretion onto Massive Black Holes and Infrared Diagnosis of the Eddington Ratio
Hidenobu Yajima, Massimo Ricotti, KwangHo Park +1
Evidence for dust around supermassive black holes (SMBHs) in the early Universe is strongly suggested by recent observations. However, the accretion mechanism of SMBHs in dusty gas…
Resolved stellar streams around NGC4631 from a Subaru/Hyper Suprime-Cam survey
Mikito Tanaka, Masashi Chiba, Yutaka Komiyama
We present the first results of the Subaru/Hyper Suprime-Cam (HSC) survey of the interacting galaxy system, NGC4631 and NGC4656. From the maps of resolved stellar populations, we i…
X-Ray bright optically faint active galactic nuclei in the Subaru Hyper Suprime-Cam wide survey
Yuichi Terashima, Makoto Suganuma, Masayuki Akiyama +8
We construct a sample of X-ray bright optically faint active galactic nuclei by combining Subaru Hyper Suprime-Cam, XMM-Newton, and infrared source catalogs. 53 X-ray sources satis…
Modelling of Lyman-alpha Emitting Galaxies and Ionized Bubbles at the Era of Reionization
Hidenobu Yajima, Kazuyuki Sugimura, Kenji Hasegawa
Understanding Ly emitting galaxies (LAEs) can be a key to reveal cosmic reionization and galaxy formation in the early Universe. Based on halo merger trees and Ly radiation t…
