  • Radio observations of a nearby type IIP SN 2012aw 
    Yadav, N; Ray, A; Chakraborti, S; Stockdale, C; Chandra, P; Smith, R; Roy, R; Dwarkadas, V; Sutaria, F. K; Pooley, D; Kumar, B; Bose, S (Cambridge University Press, 2014-01)
    SN 2012AW is a type-IIP supernova which exploded in M95. In this paper we discuss the radio observations of this supernova and model them to determine the important parameters relevant to the explosion and the evolution ...
  • SN 2012aa: a transient between type Ibc core-collapse and superluminous supernovae 
    Roy, R; Sollerman, J; Silverman, J. M; Pastorello, A; Fransson, C; Drake, A; Taddia, F; Fremling, C; Kankare, E; Brajesh Kumar; Cappellaro, E; Bose, S; Benetti, S; Filippenko, A.

    Context. Research on supernovae (SNe) over the past decade has confirmed that there is a distinct class of events which are much more luminous (by ~2 mag) than canonical core-collapse SNe (CCSNe). These events with visual ...
  • The strange case of SN 2011ja and its host 
    Chakraborti, S; Ray, A; Smith, R; Ryder, S; Yadav, N; Sutaria, F. K; Dwarkadas, V. V; Chandra, P; Pooley, D; Roy, R (Cambridge University Press, 2014-01)
    SN 2001ja was observed twice in three months using the Chandra X-Ray Observatory. The X-ray flux could be due to interaction with the circumstellar medium, perhaps dominated by the reverse shock heated thermal plasma, or ...
