Optical Behavior of GRB 061121 around its X-Ray Shallow Decay Phase
T. Uehara, M. Uemura, A. Arai +8
Aims. We report on a detailed study of the optical afterglow of GRB 061121 with our original time-series photometric data. In conjunction with X-ray observations, we discuss the or…
Infrared/optical - X-ray simultaneous observations of X-ray flares in GRB 071112C and GRB 080506
T. Uehara, M. Uemura, K. S. Kawabata +13
We investigate the origin of short X-ray flares which are occasionally observed in early stages of afterglows of gamma-ray bursts (GRBs). We observed two events, GRB 071112C and GR…
Multiband Photopolarimetric Monitoring of the Outburst of the Blazar 3C~454.3 in 2007
Mahito Sasada, Makoto Uemura, Akira Arai +12
We report on optical-near-infrared photopolarimetric observations of a blazar 3C 454.3 over 200 d. The object experienced an optical outburst in July 2007. This outburst was follow…
Bayesian Approach to Find a Long-Term Trend in Erratic Polarization Variations Observed in Blazars
Makoto Uemura, Koji S. Kawabata, Mahito Sasada +7
We developed a method to separate a long-term trend from observed temporal variations of polarization in blazars using a Bayesian approach. The temporal variation of the polarizati…
