Dust from Comet 209P/LINEAR during its 2014 Return: Parent Body of a New Meteor Shower, the May Camelopardalids
Masateru Ishiguro, Daisuke Kuroda, Hidekazu Hanayama +29
We report a new observation of the Jupiter-family comet 209P/LINEAR during its 2014 return. The comet is recognized as a dust source of a new meteor shower, the May Camelopardalids…
Discovery of Dramatic Optical Variability in SDSS J1100+4421: A Peculiar Radio-Loud Narrow-Line Seyfert 1 Galaxy?
Masaomi Tanaka, Tomoki Morokuma, Ryosuke Itoh +55
We present our discovery of dramatic variability in SDSS J1100+4421 by the high-cadence transient survey Kiso Supernova Survey (KISS). The source brightened in the optical by at le…
Kiso Supernova Survey (KISS): Survey Strategy
Tomoki Morokuma, Nozomu Tominaga, Masaomi Tanaka +58
The Kiso Supernova Survey (KISS) is a high-cadence optical wide-field supernova (SN) survey. The primary goal of the survey is to catch the very early light of a SN, during the sho…
Optical and Near-Infrared Polarimetry of Highly Reddened Type Ia Supernova 2014J: Peculiar Properties of Dust in M82
K. S. Kawabata, H. Akitaya, M. Yamanaka +46
We presented optical and near-infrared multi-band linear polarimetry of the highly reddened Type Ia SN~2014J appeared in M82. SN~2014J exhibits large polarization at shorter wavele…
Variable optical polarization during high state in gamma-ray loud narrow line Seyfert 1 galaxy 1H 0323+342
Ryosuke Itoh, Yasuyuki T. Tanaka, Hiroshi Akitaya +34
We present results of optical polarimetric and multi-band photometric observations for gamma-ray loud narrow-line Seyfert 1 galaxy 1H 0323+342. This object has been monitored by 1.…
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…
