A Significant Feature in the General Relativistic Time Evolution of the Redshift of Photons Coming from a Star Orbiting Sgr A*
Hiromi Saida, Shogo Nishiyama, Takayuki Ohgami +16
The star S0-2, orbiting the Galactic central massive black hole candidate Sgr A*, passed its pericenter in May 2018. This event is the first chance to detect the general relativist…
Interstellar Extinction Law toward the Galactic Center IV: J, H, and Ks Bands from VVV Red Clump Stars
Schun Nagatomo, Tetsuya Nagata, Shogo Nishiyama
We have determined the wavelength dependence of the extinction in the near-infrared bands (, , ) toward the Galactic center from the VVV (VISTA Variables in th…
Radial Velocity Measurements of an Orbiting Star Around Sgr A*
Shogo Nishiyama, Hiromi Saida, Yohsuke Takamori +10
During the next closest approach of the orbiting star S2/S0-2 to the Galactic supermassive black hole (SMBH), it is estimated that RV uncertainties of ~ 10 km/s allow us to detect…
Number Density Distribution of Near-Infrared Sources on a Sub-Degree Scale in the Galactic Center: Comparison with the Fe XXV Ka Line at 6.7 keV
Kazuki Yasui, Shogo Nishiyama, Tatsuhito Yoshikawa +9
The stellar distribution derived from an and -band survey of the central region of our Galaxy is compared with the Fe XXV K (6.7 keV) line intensity observed…
