J-GEM Follow-Up Observations to Search for an Optical Counterpart of The First Gravitational Wave Source GW150914
Tomoki Morokuma, Masaomi Tanaka, Yuichiro Asakura +22
We present our optical follow-up observations to search for an electromagnetic counterpart of the first gravitational wave source GW150914 in the framework of the Japanese collabor…
OISTER Optical and Near-Infrared Observations of the Super-Chandrasekhar Supernova Candidate SN 2012dn: Dust Emission from the Circumstellar Shell
Masayuki Yamanaka, Keiichi Maeda, Masaomi Tanaka +34
We present extensively dense observations of the super-Chandrasekhar supernova (SC SN) candidate SN 2012dn from to days after the date of its -band maximum in the o…
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…
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…
OAO/MITSuME Photometry of Dwarf Novae: I SU Ursae Majoris
Akira Imada, Hideyuki Izumiura, Daisuke Kuroda +5
We report on simultaneous , and photometry of SU Ursae Majoris during 2011 December - 2012 February using OAO/MITSuME. Our photometry revealed that quie…
