Optical and Near-Infrared Polarimetry for a Highly Dormant Comet 209P/LINEAR
Daisuke Kuroda, Masateru Ishiguro, Makoto Watanabe +24
We conducted an optical and near-infrared polarimetric observation of the highly dormant Jupiter-Family Comet, 209P/LINEAR. Because of its low activity, we were able to determine t…
Discovery of a Highly Polarized Optical Microflare in the Blazar S5 0716+714 During 2014 WEBT Campaign
Gopal Bhatta, Arti Goyal, Michal Ostrowski +42
The occurrence of low-amplitude flux variations in blazars on hourly timescales, commonly known as microvariability, is still a widely debated subject in high-energy astrophysics.…
OISTER Optical and Near-Infrared Observations of Type Iax Supernova 2012Z
Masayuki Yamanaka, Keiichi Maeda, Koji S. Kawabata +30
We report observations of the Type Iax supernova (SN Iax) 2012Z at optical and near-infrared wavelengths from immediately after the explosion until days after the maxi…
Probing the nature of the TeV gamma-ray binary HESS J0632+057 by monitoring Be disk variability
Yuki Moritani, Atsuo T. Okazaki, Alex C. Carciofi +9
We report on monitoring observations of the TeV gamma-ray binary HESS J0632+057, which were carried out to constrain the interaction between the Be circumstellar disk and the compa…
Rapid Variability of Blazar 3C 279 during Flaring States in 2013-2014 with Joint Fermi-LAT, NuSTAR, Swift, and Ground-Based Multi-wavelength Observations
M. Hayashida, K. Nalewajko, G. M. Madejski +49
We report the results of a multi-band observing campaign on the famous blazar 3C 279 conducted during a phase of increased activity from 2013 December to 2014 April, including firs…
An emergence of new polarized emission region in blazar Mrk 421 associated with X-ray flare
Ryosuke Itoh, Yasushi Fukazawa, Yasuyuki T. Tanaka +8
We report on long-term multi-wavelength monitoring of blazar Mrk~421 from 2010 to 2011. The source exhibited extreme X-ray flares in 2010. Our research group performed optical phot…
