Sn 2006gy : Discovery of the most luminous supernova ever recorded, powered by the death of an extremely massive star like η carinae
We report the discovery and early observations of the peculiar Type IIn supernova (SN) 2006gy in NGC 1260. With a peak visual magnitude of about -22, it is the most luminous supernova ever recorded.Expand

Spectropolarimetry of Supernovae
Overwhelming evidence has accumulated in recent years that supernova explosions are intrinsically three-dimensional phenomena with significant departures from spherical symmetry. We review theExpand

Generalized Semi-analytical Models of Supernova Light Curves
We present generalized supernova (SN) light curve (LC) models for a variety of power inputs including the previously proposed ideas of radioactive decay of {sup 56}Ni and {sup 56}Co and magnetarExpand

MEASUREMENTS OF THE RATE OF TYPE Ia SUPERNOVAE AT REDSHIFT ≲0.3 FROM THE SLOAN DIGITAL SKY SURVEY II SUPERNOVA SURVEY
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate based on data from the Sloan Digital Sky Survey II (SDSS-II) Supernova Survey. The adopted sample of supernovae (SNe)Expand

Supernova 1998bw - the final phases
The probable association with GRB 980425 immediately put SN 1998bw at the forefront of supernova research. Here, we present revised late-time BV RI light curves of the supernova, based on templateExpand

VARIABLE SODIUM ABSORPTION IN A LOW-EXTINCTION TYPE Ia SUPERNOVA*, **
Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but it may suggest theExpand

SN 1992A : ultraviolet and optical studies based on HST, IUE and CTIO observations
The Type Ia supernova SN 1992A in the SO galaxy NGC 1380 was observed as a target of opportunity by the International Ultrauiolet Explorer (IUE) and with great alacrity by the Hubble Space TelescopeExpand
