The Infrared Luminosity Function of AKARI 90m Galaxies in the Local Universe
Ece Kilerci-Eser, Tomotsugu Goto
Local infrared (IR) luminosity functions (LFs) are necessary benchmarks for high-redshift IR galaxy evolution studies. Any accurate IR LF evolution studies require accordingly accu…
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…
Surface density: a new parameter in the fundamental metallicity relation of star-forming galaxies
Tetsuya Hashimoto, Tomotsugu Goto, Rieko Momose
Star-forming galaxies display a close relation among stellar mass, metallicity and star-formation rate (or molecular-gas mass). This is known as the fundamental metallicity relatio…
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…
Overview of North Ecliptic Pole Deep multi-wavelength Survey (NEP-Deep)

The recent updates of the North Ecliptic Pole deep (0.5~deg, NEP-Deep) multi-wavelength survey covering from X-ray to radio-wave is presented. The NEP-Deep provides us with sev…
GOLDRUSH. III. A Systematic Search of Protoclusters at Based on the Area
Jun Toshikawa, Hisakazu Uchiyama, Nobunari Kashikawa +15
We conduct a systematic search for galaxy protoclusters at based on the latest internal data release (S16A) of the Hyper SuprimeCam Subaru strategic program (HSC-SSP). I…
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…
SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES): Faint-End Counts at 450 um
Wei-Hao Wang, Wei-Ching Lin, Chen-Fatt Lim +40
The SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES) is a three-year JCMT Large Program aiming at reaching the 450 m confusion limit in the COSMOS-CANDELS region, to study a repr…
No Ly emitters detected around a QSO at z=6.4: Suppressed by the QSO?
Tomotsugu Goto, Yousuke Utsumi, Satoshi Kikuta +3
Understanding how QSO's UV radiation affects galaxy formation is vital to our understanding of reionization era. Using a custom made narrow-band filter, , on Subaru/Suprime-…
The mass--metallicity relation AKARI-FMOS infrared galaxies at in the AKARI North Ecliptic Pole Deep Survey Field
Nagisa Oi, Tomotsugu Goto, Matthew Malkan +2
Mass, metallicity, and star formation rate (SFR) of a galaxy are crucial parameters in understanding galaxy formation and evolution. However, the relation among these is still a ma…
