Environmental Effects on AGN activity via Extinction-free Mid-Infrared Census
Daryl Joe D. Santos, Tomotsugu Goto, Seong Jin Kim +20
How does the environment affect active galactic nucleus (AGN) activity? We investigated this question in an extinction-free way, by selecting 1120 infrared galaxies in the …
Optically-detected galaxy cluster candidates in the North Ecliptic Pole field based on photometric redshift from Subaru Hyper Suprime-Cam
T. -C. Huang, H. Matsuhara, T. Goto +23
Galaxy clusters provide an excellent probe in various research fields in astrophysics and cosmology. However, the number of galaxy clusters detected so far in the North Ecl…
An Active Galactic Nucleus Recognition Model based on Deep Neural Network
Bo Han Chen, Tomotsugu Goto, Seong Jin Kim +21
To understand the cosmic accretion history of supermassive black holes, separating the radiation from active galactic nuclei (AGNs) and star-forming galaxies (SFGs) is critical. Ho…
Photometric Redshifts in the North Ecliptic Pole Wide Field based on a Deep Optical Survey with Hyper Suprime-Cam
Simon C. -C. Ho, Tomotsugu Goto, Nagisa Oi +13
The space infrared telescope has performed near- to mid-infrared (MIR) observations on the North Ecliptic Pole Wide (NEPW) field (5.4 deg) for about one year. t…
Identification of AKARI infrared sources by Deep HSC Optical Survey: Construction of New Band-Merged Catalogue in the NEP-Wide field
Seong Jin Kim, Nagisa Oi, Tomotsugu Goto +21
The north ecliptic pole (NEP) field is a natural deep field location for many satellite observations. It has been targeted manytimes since it was surveyed by the AKARI space telesc…
CFHT MegaPrime/MegaCam -band source catalogue of the North Ecliptic Pole Wide field
T. -C. Huang, H. Matsuhara, T. Goto +10
The infrared (IR) space telescope conducted two surveys (Deep and Wide) in the North Ecliptic Pole (NEP) field to find more than 100,000 IR sources using its Infrared Camer…
Search for Optically Dark Infrared Galaxies without Counterparts of Subaru Hyper Suprime-Cam in the AKARI North Ecliptic Pole Wide Survey Field
Yoshiki Toba, Tomotsugu Goto, Nagisa Oi +25
We present the physical properties of AKARI sources without optical counterparts in optical images from the Hyper Suprime-Cam (HSC) on the Subaru telescope. Using the AKARI infrare…
CO luminosity-Linewidth correlation of low and high redshift galaxies and its possible cosmological utilization
Yi-han Wu, Tomotsugu Goto, Ece Kilerci Eser +4
A linear correlation has been proposed between the CO luminosity () and full-width at half maximum (FWHM) for high-redshift (z > 1) submillimeter galaxie…
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…
AGN selection by 18-band SED fitting in mid-infrared in the AKARI NEP deep field
Ting-Chi Huang, Tomotsugu Goto, Tetsuya Hashimoto +2
In this research, we provide a new, efficient method to select infrared (IR) active galatic nucleus (AGN). In the past, AGN selection in IR had been established by many studies usi…
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…
An extinction free AGN selection by 18-band SED fitting in mid-infrared in the AKARI NEP deep field
Ting-Chi Huang, Tomotsugu Goto, Tetsuya Hashimoto +2
We have developed an efficient Active Galactic Nucleus (AGN) selection method using 18-band Spectral Energy Distribution (SED) fitting in mid-infrared (mid-IR). AGNs are often obsc…
