Spectropolarimetry of the Unique Type Ib Supernova 2005bf: Larger Asymmetry Revealed by Later-Phase Data
Masaomi Tanaka, Koji S. Kawabata, Keiichi Maeda +6
We present an optical spectropolarimetric observation of the unique Type Ib supernova (SN) 2005bf at 8 days after the second maximum. The data, combined with the polarization spect…
SN 2006aj Associated with XRF 060218 At Late Phases: Nucleosynthesis-Signature of A Neutron Star-Driven Explosion
Keiichi Maeda, Koji Kawabata, Masaomi Tanaka +9
Optical spectroscopy and photometry of SN 2006aj have been performed with the Subaru telescope at t > 200 days after GRB060218, the X-ray Flash with which it was associated. Strong…
Giant Steps in Cefalu
David J. Jeffery, Paolo A. Mazzali
Giant steps is a technique to accelerate Monte Carlo radiative transfer in optically-thick cells of astrophysical atmospheres by greatly reducing the number of Monte Carlo steps ne…
3D Models for High Velocity Features in Type Ia Supernovae
Masaomi Tanaka, Paolo A. Mazzali, Keiichi Maeda +1
Spectral synthesis in 3-dimensional (3D) space for the earliest spectra of Type Ia supernovae (SNe Ia) is presented. In particular, the high velocity absorption features that are c…
The Unique Type Ib Supernova 2005bf: A WN Star Explosion Model for Peculiar Light Curves and Spectra
N. Tominaga, M. Tanaka, K. Nomoto +22
Observations and modeling for the light curve (LC) and spectra of supernova (SN) 2005bf are reported. This SN showed unique features: the LC had two maxima, and declined rapidly af…
Death rate of massive stars at redshift ~0.3
E. Cappellaro, M. Riello, G. Altavilla +10
We report the first result of a supernova search program designed to measure the evolution of the supernova rate with redshift. To make the comparison with local rates more signifi…
