Near-infrared Polarimetry of flares from Sgr A* with Subaru/CIAO
Shogo Nishiyama, Motohide Tamura, Hirofumi Hatano +5
We have performed near-infrared monitoring observations of Sgr A*, the Galactic center radio source associated with a supermassive black hole, with the near-infrared camera CIAO an…
A near-infrared survey of Miras and the distance to the Galactic Centre
Noriyuki Matsunaga, Takahiro Kawadu, Shogo Nishiyama +5
We report the results of a near-infrared survey for long-period variables in a field of view of 20 arcmin by 30 arcmin towards the Galactic Centre (GC). We have detected 1364 varia…
Interstellar Extinction Law toward the Galactic Center III: J, H, Ks bands in the 2MASS and the MKO systems, and 3.6, 4.5, 5.8, 8.0 micron in the Spitzer/IRAC system
Shogo Nishiyama, Motohide Tamura, Hirofumi Hatano +4
We have determined interstellar extinction law toward the Galactic center (GC) at the wavelength from 1.2 to 8.0 micron, using point sources detected in the IRSF/SIRIUS near-infrar…
