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…
A Study of the Long-term Spectral Variations of 3C 66A Observed with the Fermi and Kanata Telescopes
Ryosuke Itoh, Yasushi Fukazawa, James Chiang +25
3C 66A is an intermediate-frequency-peaked BL Lac object detected by the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope. We present a study of the long-term varia…
Multi-Wavelength Photometric and Polarimetric Observations of the Outburst of 3C 454.3 in Dec. 2009
Mahito Sasada, Makoto Uemura, Yasushi Fukazawa +11
In December 2009, the bright blazar, 3C 454.3 exhibited a strong outburst in the optical, X-ray and gamma-ray regions. We performed photometric and polarimetric monitoring of this…
Photopolarimetric Monitoring of Blazars in the Optical and Near-Infrared Bands with the Kanata Telescope. I. Correlations between Flux, Color, and Polarization
Yuki Ikejiri, Makoto Uemura, Mahito Sasada +10
We report on the correlation between the flux, color and polarization variations on time scales of days--months in blazars, and discuss their universal aspects. We performed monito…
