Extremely high polarization in 2010 outburst of blazar 3C 454.3
Mahito Sasada, Makoto Uemura, Yasushi Fukazawa +16
The gamma-ray-detected blazar 3C 454.3 exhibits dramatic flux and polarization variations in the optical and near-infrared bands. In December 2010, the object emitted a very bright…
GRB 091208B: First Detection of the Optical Polarization in Early Forward Shock Emission of a Gamma-Ray Burst Afterglow
T. Uehara, K. Toma, K. S. Kawabata +19
We report that the optical polarization in the afterglow of GRB 091208B is measured at t = 149 - 706 s after the burst trigger, and the polarization degree is P = 10.4% +/- 2.5%. T…
Early phase observations of extremely luminous Type Ia Supernova 2009dc
M. Yamanaka, K. S. Kawabata, K. Kinugasa +31
We present early phase observations in optical and near-infrared wavelengths for the extremely luminous Type Ia supernova (SN Ia) 2009dc. The decline rate of the light curve is $Δm…
