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…
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)…
General formulae for the periapsis shift of a quasi-circular orbit in static spherically symmetric spacetimes and the active gravitational mass density
Tomohiro Harada, Takahisa Igata, Hiromi Saida +1
We study the periapsis shift of a quasi-circular orbit in general static spherically symmetric spacetimes. We derive two formulae in full order with respect to the gravitational fi…
Periapsis shifts in dark matter distribution with a dense core
Takahisa Igata, Yohsuke Takamori
We consider the periapsis shifts in dark matter distribution with a dense core. We model the dark matter distribution as an isotropic gas sphere, the Emden polytropic sphere of ind…
Periapsis shifts in dark matter distribution around a black hole
Takahisa Igata, Tomohiro Harada, Hiromi Saida +1
We consider the periapsis shifts of bound orbits of stars on static clouds around a black hole. The background spacetime is constructed from a Schwarzschild black hole surrounded b…
