  • Deep optical survey of the stellar content of Sh2-311 region 
    Yadav, Ram Kesh; Pandey, A. K; Sharma, Saurabh; Jose, J; Ogura, K; Kobayashi, N; Samal, M. R; Eswaraiah, C; Chandola, H. C (Elsevier, 2015-01)
    The stellar content in and around Sh2-311 region have been studied using the deep optical observations as well as near-infrared (NIR) data from 2MASS. The region contains three clusters, viz. NGC 2467, Haffner 18 and Haffner ...
  • A Low-Frequency Study of Recently Identified Double-Double Radio Galaxies 
    Nandi, S; Saikia, D. J; Roy, R; Dabhade, P.; Wadadekar, Y; Larsson, J; Baes, M; Chandola, H. C; Singh, M (Oxford University Press on behalf of the Royal Astronomical Society, 2019-07)
    n order to understand the possible mechanisms of recurrent jet activity in radio galaxies and quasars, which are still unclear, we have identified such sources with a large range of linear sizes (220–917 kpc), and hence ...
  • Optical Photometric and Polari metric investigation of NGC 1931 
    Pandey, A. K; Eswaraiah, C; Sharma, S; Samal, M. R; Chauhan, N; Chen, W. P; Jose, J; Ojha, D. K; Yadav, Ram Kesh; Chandola, H. C (IOP Publishing, 2013-02-05)
    We present optical photometric and polarimetric observations of stars toward NGC 1931 with the aim of deriving cluster parameters such as distance, reddening, age, and luminosity/mass function as well as understanding dust ...
  • SN 2013ab: a normal type IIP supernova in NGC 5669 
    Bose, S; Valenti, S; Misra, K; Pumo, M. L; Zampieri, L; Sand, D; Kumar, B; Pastorello, A; Sutaria, F. K; Maccarone, T. J; Kumar, B; Graham, M. L; Howell, D. A; Ochner, P; Chandola, H. C; Pandey, S. B (Oxford University Press on behalf of the Royal Astronomical Society, 2015-07-01)
    We present densely sampled ultraviolet/optical photometric and low-resolution optical spectroscopic observations of the Type IIP supernova 2013ab in the nearby (∼24 Mpc) galaxy NGC 5669, from 2 to 190 d after explosion. ...
  • SN 2013ej: a type IIL supernova with weak signs of interaction 
    Bose, S; Sutaria, F. K; Kumar, B; Duggal, C; Misra, K; Brown, P. J; Singh, M; Dwarkadas, V; York, D. G; Chakraborti, S; Chandola, H. C; Dahlstrom, J; Ray, A; Safonova, M (IOP Publishing, 2015-06)
    We present optical photometric and spectroscopic observations of SN 2013ej. It is one of the brightest Type II supernovae (SNe II) exploded in a nearby (∼10 Mpc) galaxy, NGC 628. The light-curve characteristics are similar ...
  • Supernova 2012aw – a high-energy clone of archetypal Type IIP SN 1999em 
    Bose, Subhash; Kumar, Brijesh; Sutaria, F. K; Kumar, Brajesh; Roy, Rupak; Bhatt, V. K; Pandey, S. B; Chandola, H. C; Sagar, R; Misra, Kuntal; Chakraborti, Sayan (Oxford University Press, 2013-08-11)
    We present densely sampled UBVRI/griz photometric and low-resolution (6–10 Å) optical spectroscopic observations from 4 to 270 d after explosion of a newly discovered Type II SN 2012aw in a nearby (∼9.9 Mpc) galaxy M95. ...
