Optical Properties of Interstellar Dust around the Orion A Molecular Cloud
Hayato Uehara, Kazuhito Dobashi, Shingo Nishiura +2
We have studied optical properties of interstellar dust around the Orion A molecular cloud to investigate the size distribution and the composition of dust grains. Orion A is one o…
New 60-cm Radio Survey Telescope with the Sideband-Separating SIS Receiver for the 200 GHz Band
Taku Nakajima, Masahiro Kaiden, Jun Korogi +10
We have upgraded the 60-cm radio survey telescope located in Nobeyama, Japan. We developed a new waveguide-type sideband-separating SIS mixer for the telescope, which enables the s…
Multi-color Shallow Decay and Chromatic Breaks in the GRB 050319 Optical Afterglow
K. Y. Huang, Y. Urata, P. H. Kuo +19
Multi-wavelength B, V, R, I observations of the optical afterglow of GRB 050319 were performed by the 1.05-m telescope at Kiso Observatory and the 1.0-m telescope at Lulin Observat…
Kiso observations for 20 GRBs in HETE-2 era
Y. Urata, Y. Nakada, T. Miyata +7
We have established a GRB follow-up observation system at Kiso observatory (Japan) in 2001. Since the east Asian area had been blank for the GRB follow-up observational network, th…
Early (0.3 day) R-band light curve of the optical afterglow of GRB030329
Y. Urata, T. Miyata, S. Nishiura +13
We observed the optical afterglow of the bright gamma-ray burst GRB030329 on the nights of 2003 March 29, using the Kiso observatory (the University of Tokyo) 1.05 m Schmidt telesc…
Multi-band optical follow-up observations of GRB 020813 at KISO and Bisei observatories
Y. Urata, S. Nishiura, T. Miyata +9
Observations were made of the optical afterglow of GRB020813 (Fox, Blake & Price, 2002) with the KISO observatory 1.05 m Schmidt telescope and the Bisei astronomical observatory 1.…
