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…
No redshift evolution of non-repeating fast radio-burst rates
Tetsuya Hashimoto, Tomotsugu Goto, Alvina Y. L. On +6
Fast radio bursts (FRBs) are millisecond transients of unknown origin(s) occurring at cosmological distances. Here we, for the first time, show time-integrated-luminosity functions…
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…
Fast radio bursts to be detected with the Square Kilometre Array
Tetsuya Hashimoto, Tomotsugu Goto, Alvina Y. L. On +6
Fast radio bursts (FRBs) are mysterious extragalactic radio signals. Revealing their origin is one of the central foci in modern astronomy. Previous studies suggest that occurrence…
Far-infrared star-formation rates of six GRB host galaxies with ALMA
Tiger Yu-Yang Hsiao, Tetsuya Hashimoto, Jia-Yuan Chang +7
Gamma-Ray Bursts (GRBs) can be a promising tracer of cosmic star-formation rate history (CSFRH). In order to reveal the CSFRH using GRBs, it is important to understand whether they…
What determines the maximum stellar surface density of galaxies?
Chih-Teng Ling, Tetsuya Hashimoto, Tomotsugu Goto +5
Observationally, it has been reported that the densest stellar system in the Universe does not exceed a maximum stellar surface density, = Mpc…
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…
Luminosity-duration relations and luminosity functions of repeating and non-repeating fast radio bursts
Tetsuya Hashimoto, Tomotsugu Goto, Ting-Wen Wang +5
Fast radio bursts (FRBs) are mysterious radio bursts with a time scale of approximately milliseconds. Two populations of FRB, namely repeating and non-repeating FRBs, are observati…
Subaru medium-resolution spectra of a QSO at z=6.62: Three reionization tests
Ting-Yi Lu, Tomotsugu Goto, Ji-Jia Tang +9
Investigating the Gunn-Peterson trough of high redshift quasars (QSOs) is a powerful way to reveal the cosmic reionization. As one of such attempts, we perform a series of analyses…
