ASTROPHYSICAL JOURNAL LETTERS   795(1)    Nov 2014   [Refereed]
We present optical and near-infrared multi-band linear polarimetry of the highly reddened Type Ia supernova (SN) 2014J that appeared in M82. SN 2014J exhibits large polarization at shorter wavelengths, e.g., 4.8% in the B band, which decreases rap...

NATURE   465(7296) 326-328   May 2010   [Refereed]
The unusual helium-rich (type Ib) supernova SN 2005E is distinguished from all supernovae hitherto observed by its faint and rapidly fading light curve, prominent calcium lines in late-phase spectra and lack of any mark of recent star formation ne...

Supernova (SN) 2006gy is an extremely luminous Type IIn SN characterized by the bright peak magnitude M-R similar to -22 mag and its long duration. The mechanism giving rise to its huge luminosity is still unclear. We performed optical spectroscop...

MEXT: KAKENHI
Project Year: 2011 - 2013    Investigator(s): YOSHIDA, Michitoshi
We made performance evaluations of InGaAs near-infrared image sensor which are produced by Hamamatsu Photonics Co. Ltd. (HPK) under cold environment in collaboration with HPK. We tested a 64 x 64 pixels with 50 micron pitch array and 128 x 128 pix...

Project Year: 2011 - 2013    Investigator(s): KAWABATA, koji
We have developed a wide-band polarimetric module dedicated for the Hiroshima Optical and Near-InfraRed camera (HONIR) and realized a high-precision polarimetric capability at wavelengths 0.5 -- 2.4 microns. We also performed polarimetric monitori...

Project Year: 2008 - 2011    Investigator(s): KAWABATA, Koji
We have developed an automatic observation system with` Kanata' 1. 5-m high-speed moving telescope and an wide-field optical polarimeter HOWPol, and discussed the magnetic structure of GRB relativistic jets on the basis of the polarization of earl...
