  • Discovery and rapid follow-up observations of the unusual type II SN 2018ivc in NGC 1068 
    Bostroem, K. A; Valenti, S; Sand, D. J; Andrews, J. E; Van Dyk, S. D; Galbany, L; Pooley, D; Amaro, R. C; Smith, N; Yang, S; Anupama, G. C; Arcavi, I; Baron, E; Brown, P. J; Burke, J; Cartier, R; Hiramatsu, D; Dastidar, R; DerKacy, J. M; Dong, Y; Egami, E; Ertel, S; Filippenko, A. V; Fox, O. D; Haislip, J; Hosseinzadeh, G; Howell, D. A; Gangopadhyay, A; Jha, S. W; Kouprianov, V; Kumar, B; Lundquist, M; Milisavljevic, D; McCully, C; Milne, P; Misra, K; Reichart, D. E; Sahu, D. K; Sai, H; Singh, A; Smith, P. S; Vinko, J; Wang, X; Wang, Y; Wheeler, J. C; Williams, G. G; Wyatt, S; Zhang, J; Zhang, X (IOP Publishing, 2020-05-20)
    We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual SNe II that exploded in NGC 1068 (D = 10.1 Mpc). The light curve of SN 2018ivc declines piecewise-linearly, changing slope ...
  • Electron Cooling in a Young Radio Supernova: SN 2012aw 
    Yadav, N; Ray, A; Chakraborti, S; Stockdale, C; Chandra, P; Smith, R; Roy, R; Bose, S; Dwarkadas, V; Sutaria, F. K; Pooley, D (IOP Publishing, 2014-02-10)
    We present the radio observations and modeling of an optically bright Type II-P supernova (SN), SN 2012aw which exploded in the nearby galaxy Messier 95 (M95) at a distance of 10 Mpc. The spectral index values calculated ...
  • Probing final stages of stellar evolution with x-ray observations of SN 2013ej 
    Chakraborti, S; Ray, A; Smith, R; Margutti, R; Pooley, D; Bose, S; Sutaria, F. K; Chandra, P; Dwarkadas, V. V; Ryder, S; Maeda, K (IOP Publishing, 2016-01)
    Massive stars shape their surroundings with mass loss from winds during their lifetimes. Fast ejecta from supernovae (SNe), from these massive stars, shock this circumstellar medium. Emission generated by this interaction ...
  • The Progenitor of SN 2011ja: Clues from Circumstellar Interaction 
    Chakraborti, S; Ray, A; Smith, R; Ryder, S; Yadav, N; Sutaria, F. K; Dwarkadas, V. V; Chandra, P; Pooley, D; Roy, R (IOP Publishing, 2013-09-01)
    Massive stars, possibly red supergiants, which retain extended hydrogen envelopes until core collapse, produce Type II plateau (IIP) supernovae. The ejecta from these explosions shocks the circumstellar matter originating ...
  • 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 ...
  • 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 ...
