Implications of aging in young supernovae
Poonam Chandra, Alak Ray
We present here the combined radio spectrum from the Giant Metrewave Radio Telescope (GMRT) and Very Large Array (VLA) of type-IIb SN 1993J (age 11 years) and a type-Ic SN 2003bg (…
Baby supernovae through the looking glass at long wavelengths
Poonam Chandra, Alak Ray
We emphasize the importance of observations of young supernovae in wide radio band. We argue on the basis of observational results that only high or only low frequency data is not…
Low frequency observations of SN 1993J with Giant Meterwave Radio Telescope
P. Chandra, A. Ray, S. Bhatnagar
In this paper, we discuss the low frequency spectrum of SN 1993J with GMRT. We observed SN 1993J at several epochs in 20cm, 50cm, 90cm and 125cm wavelengths and achieved near simul…
Radio Studies of Young Core Collapse Supernovae
Poonam Chandra, Alak Ray, Sanjay Bhatnagar
Multi-frequency observations of two radio bright SNe (SN1993J, SN1979C) carried out over a year with GMRT are presented. Their radio light curves trace the evolution of the mass lo…
