    We present early-time optical and near-infrared photometry of supernova (SN) 2005cf. The observations, spanning a period from about 12 d before to 3 months after maximum, have been obtained through the coordination of ...
  • Light curve and spectral evolution of the Type IIb supernova 2011fu 
    Kumar, Brajesh; Pandey, S. B; Sahu, D. K; Vinko, J; Moskvitin, A. S; Anupama, G. C; Bhatt, V. K; Ordasi, A; Nagy, A; Sokolov, V. V; Sokolova, T. N; Komarova, V. N; Kumar, Brijesh; Bose, S; Roy, R; Sagar, R (Oxford University Press on behalf of the Royal Astronomical Society, 2013-05-01)
    We present the low-resolution spectroscopic and UBVRI broad-band photometric investigations of the Type IIb supernova (SN) 2011fu, discovered in UGC 01626. The photometric follow-up of this event was initiated a few days ...
  • One year of monitoring of the Type IIb supernova SN 2011dh 
    Sahu, D. K; Anupama, G. C; Chakradhari, N. K (Oxford University Press on behalf of the Royal Astronomical Society, 2013-07-21)
    Optical UBVRI photometry and low-resolution spectroscopy of the Type IIb supernova SN 2011dh in M51 are presented, covering the first year after the explosion. The light curve and spectral evolution are discussed. The early ...
  • The Peculiar Type Ib Supernova SN 2005bf: Explosion of a Massive He Star with a Thin Hydrogen Envelope? 
    Anupama, G. C; Sahu, D. K; Deng, J; Nomoto, K; Tominaga, N; Tanaka, M; Mazzali, P. A; Prabhu, T. P (University of Chicago Press, 2005-09)
    We present BVRI photometry and optical spectroscopy of SN 2005bf near maximum light. The maximum phase is broad and occurred around 2005 May 7, about 40 days after the shock breakout. SN 2005bf has a peak bolometric magnitude ...
  • Photometric and spectroscopic evolution of supernova SN 2009an: another case of a transitional Type Ia event 
    Sahu, D. K; Anupama, G. C; Anto, P (Oxford University Press on behalf of the Royal Astronomical Society, 2013-04-01)
    We present optical UBVRI photometry and medium-resolution spectroscopy of a transitional Type Ia supernova, SN 2009an, over the period −6 to +150 d from the B maximum. With a Δm15(B) = 1.514 ± 0.132, SN 2009an declines ...
  • Photometric and spectroscopic evolution of the Type IIP supernova SN 2004et 
    Sahu, D. K; Anupama, G. C; Srividya, S; Muneer, S (Blackwell Publishing, 2006-09)
    We present optical photometry and spectroscopy of the Type IIP supernova SN 2004et that occurred in the nearby galaxy NGC 6946. The observations span a time range of 8–541 d after explosion. The late time bolometric ...
  • Photometric study of type Ia supernova SN 2002hu 
    Sahu, D. K; Anupama, G. C; Prabhu, T. P (Blackwell Publishing, 2006-01)
    Optical UBVRI photometry of the type Ia supernova (SN Ia) SN 2002hu covering the period from −2 to +73 d since B maximum is presented. The supernova reached at maximum brightness in B on JD 245 2591.78 ± 0.5 with an apparent ...
  • A tale of two GRB-SNe at a common redshift of z=0.54
