Cosmic star formation history revealed by AKARI and Hyper Suprime-Cam
Tomo Goto, Nagiosa Oi, Ece Kilerci Eser +12
Understanding infrared (IR) luminosity is fundamental to understanding the cosmic star formation history and AGN evolution. Japanese infrared satellite, AKARI, provided unique data…
North Ecliptic Pole multi-wavelength survey : new optical data with Hyper Suprime-Cam and near-future prospects with eROSITA
Nagisa Oi, Hideo Matsuhara, Tomotsugu Goto +19
The AKARI North Ecliptic Pole (NEP) survey consists of two survey projects: NEP-Deep (0.5 sq.deg) and NEP-Wide (5.4 sq.deg), providing with tens of thousands of galaxies. A continu…
No sign of strong molecular gas outflow in an infrared-bright dust-obscured galaxy with strong ionized-gas outflow
Yoshiki Toba, Shinya Komugi, Tohru Nagao +4
We report the discovery of an infrared (IR)-bright dust-obscured galaxy (DOG) that shows a strong ionized-gas outflow but no significant molecular gas outflow. Based on detail anal…
Infrared Selection of Obscured Active Galactic Nuclei in the COSMOS Field
Yu-Yen Chang, Emeric Le Floc'h, Stéphanie Juneau +13
We present a study of the connection between black hole accretion, star formation, and galaxy morphology at z<=2.5. We focus on active galactic nuclei (AGNs) selected by their mid-…
Ionized gas outflows in infrared-bright dust-obscured galaxies selected with WISE and SDSS
Yoshiki Toba, Hyun-Jin Bae, Tohru Nagao +5
We present the ionized gas properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that show an extreme optical/IR color, , selected with the Sl…
Active Galactic Nuclei with a Low-Metallicity Narrow-Line Region
Kota Kawasaki, Tohru Nagao, Yoshiki Toba +2
Low-metallicity active galactic nuclei (AGNs) are interesting to study the early phase of the AGN evolution. However most AGNs are chemically matured and accordingly low-metallicit…
