Chandra Survey in the AKARI North Ecliptic Pole Deep Field Optical/Infrared Identifications of X-ray Sources
T. Miyaji, B. A. Bravo-Navarro, J. Díaz Tello +17
We present a catalog of optical and infrared identifications (ID) of X-ray sources in the AKARI North Ecliptic Pole (NEP) Deep field detected with Chandra covering $\sim 0.34\,{\rm…
Amplification and saturation of turbulent magnetic field in collapsing primordial gas clouds
Sho Higashi, Hajime Susa, Christoph Federrath +1
Recent numerical studies suggest that magnetic fields play an important role in primordial star formation in the early universe. However, the detailed evolution of the magnetic fie…
Quasar Luminosity Function at z = 7
Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +41
We present the quasar luminosity function (LF) at , measured with 35 spectroscopically confirmed quasars at . The sample of 22 quasars from the Subaru High-…
Combining the CLAUDS & HSC-SSP surveys: U+grizy(+YJHKs) photometry and photometric redshifts for 18M galaxies in the 20 deg2 of the HSC-SSP Deep and ultraDeep fields
G. Desprez, V. Picouet, T. Moutard +21
We present the combination of the Canada-France-Hawaii Telescope (CHFT) Large Area -bands Deep Survey (CLAUDS) and the Hyper-Suprime-Cam (HSC) Subaru Strategic Program (HSC-SSP)…
Event Horizon Telescope observations of the jet launching and collimation in Centaurus A
Michael Janssen, Heino Falcke, Matthias Kadler +236
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…
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…
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…
CHORUS. I. Cosmic HydrOgen Reionization Unveiled with Subaru: Overview
Akio K. Inoue, Satoshi Yamanaka, Masami Ouchi +28
To determine the dominant sources for cosmic reionization, the evolution history of the global ionizing fraction, and the topology of the ionized regions, we have conducted a deep…
Extinction-free Census of AGNs in the /IRC North Ecliptic Pole Field from 23-band Infrared Photometry from Space Telescopes
Ting-Wen Wang, Tomotsugu Goto, Seong Jin Kim +21
In order to understand the interaction between the central black hole and the whole galaxy or their co-evolution history along with cosmic time, a complete census of active galacti…
The Faint End of the Quasar Luminosity Function at from the Subaru Hyper Suprime-Cam Survey
Mana Niida, Tohru Nagao, Hiroyuki Ikeda +17
We present the quasar luminosity function at derived from the optical wide-field survey data obtained as a part of the Subaru strategic program (SSP) with Hyper Suprime-…
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…

Takuji Yamashita, Tohru Nagao, Hiroyuki Ikeda +17
We report a discovery of radio galaxy, HSC J083913.17+011308.1, by using the Lyman break technique with the Hyper Suprime-Cam Subaru Strategic Survey (HSC-SSP) catalog f…
Search for a Variation of the Fine Structure around the Supermassive Black Hole in Our Galactic Center
A. Hees, T. Do, B. M. Roberts +11
Searching for space-time variations of the constants of Nature is a promising way to search for new physics beyond General Relativity and the standard model motivated by unificatio…
Relativistic redshift of the star S0-2 orbiting the Galactic center supermassive black hole
Tuan Do, Aurelien Hees, Andrea Ghez +26
General Relativity predicts that a star passing close to a supermassive black hole should exhibit a relativistic redshift. We test this using observations of the Galactic center st…
