Optical observations of the fast declining type Ib supernova iPTF13bvn
Shubham Srivastav, G. C. Anupama, D. K. Sahu
We present optical UBVRI photometry and medium resolution spectroscopy of the type Ib supernova iPTF13bvn, spanning a phase of d to d with respect to -band…

J. P. Ninan, D. K. Ojha, S. K. Ghosh +12
We describe the TIFR Near Infrared Spectrometer and Imager (TIRSPEC) designed and built in collaboration with M/s. Mauna Kea Infrared LLC, Hawaii, USA, now in operation on the side…
Supernova SN 2012dn: A spectroscopic clone of SN 2006gz
N. K. Chakradhari, D. K. Sahu, S. Srivastav +1
We present optical and UV analysis of the luminous type Ia supernova SN 2012dn covering the period 11 to +109 days with respect to the band maximum, that occurred on JD…
iPTF13bvn: The First Evidence of a Binary Progenitor for a Type Ib Supernova
Melina C. Bersten, Omar G. Benvenuto, Gaston Folatelli +6
The recent detection in archival HST images of an object at the the location of supernova (SN) iPTF13bvn may represent the first direct evidence of the progenitor of a Type Ib SN.…
