  • Comprehensive multiwavelength modelling of the afterglow of GRB 050525A 
    Resmi, L; Misra, K; Johannesson, G; Castro-Tirado, A. J; Gorosabel, J; Jelınek, M; Bhattacharya, D; Kubanek, P; Anupama, G. C; Sota, A; Sahu, D. K; de Ugarte Postigo, A; Pandey, S. B; Sanchez-Ramırez, R; Bremer, M; Sagar, R (Wiley-Blackwell, 2012-11)
    The Swift era has posed a challenge to the standard blast-wave model of gamma-ray burst (GRB) afterglows. The key observational features expected within the model are rarely observed, such as the achromatic steepening ...
  • The dark nature of GRB 051022 and its host galaxy 
    Castro-Tirado, A. J; Bremer, M; McBreen, S; Gorosabel, J; Guziy, S; Fakthullin, T. A; Sokolov, V. V; González Delgado, R. M; Bihain, G; Pandey, S. B; Jelínek, M; de Ugarte Postigo, A; Misra, K; Sagar, R; Bama, P; Kamble, A. P; Anupama, G. C; Licandro, J; Pérez-Ramírez, D; Bhattacharya, D; Aceituno, F. J; Neri, R (EDP Sciences, 2007-11)
    Aims.We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 h and ~1.15 yr after the event. It is the most intense gamma-ray burst (~10-4 erg cm-2) detected by HETE-2, ...
  • The latest two GRB detected by Hete-2: GRB 051022 and GRB 051028 
    Castro-Tirado, A. J; McBreen, S; Jelínek, M; Pandey, S. B; Bremer, M; de Ugarte Postigo, A; Gorosabel, J; Guziy, S; Bihain, G; Caballero, J. A; Ferrero, P; de Jong, J; Misra, K; Sahu, D. K (American Institute of Physics, 2006-05)
    We present multiwavelength observations of the latest two GRB detected by Hete-2 in 2005. For GRB 051022, no optical/nIR afterglow has been detected, in spite of the strong gamma-ray emission and the reported X-ray afterglow ...
  • Multiwavelength Analysis of the Intriguing GRB 061126: The Reverse Shock Scenario and Magnetization 
    Gomboc, A; Kobayashi, S; Guidorzi, C; Melandri, A; Mangano, V; Sbarufatti, B; Mundell, C. G; Schady, P; Smith, R. J; Updike, A. C; Kann, D. A; Misra, K; Rol, E; Pozanenko, A; Castro-Tirado, A. J; Anupama, G. C; Bersier, D; Bode, M. F; Carter, D; Curran, P; Fruchter, A; Graham, J; Hartmann, D. H; Ibrahimov, M; Levan, A; Monfardini, A; Mottram, C. J; O'Brien, P. T; Prema, P; Sahu, D. K; Steele, I. A; Tanvir, N. R; Wiersema, K (The American Astronomical Society, 2008-11)
    We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multicolor optical imaging from 10 ground-based telescopes. GRB 061126 was a long burst (T90=191 s) with ...
  • Optical observations of GRB 060124 afterglow: a case for an injection break 
    Misra, K; Bhattacharya, D; Sahu, D. K; Sagar, R; Anupama, G. C; Castro-Tirado, A. J; Guziy, S. S; Bhatt, B. C (EDP Sciences, 2007-03)
    Aims.We present broad band optical afterglow observations of a long duration GRB 060124 using the 1.04-m Sampurnanand Telescope at ARIES, Nainital and the 2.01-m HCT at IAO, Hanle, including the earliest ground-based ...
  • Photometric and spectroscopic study of a highly reddened type Ia supernova SN 2003hx in NGC 2076 
    Misra, K; Sahu, D. K; Anupama, G. C; Pandey, K (Royal Astronomical Society, 2008-09)
    We present UBVRI CCD photometry and optical spectra of the type Ia supernova SN 2003hx which appeared in the galaxy NGC 2076, obtained till ∼ 146 d after the epoch of B-band maximum. The supernova reached at maximum ...
  • The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125 
    Updike, A. C; Haislip, J. B; Nysewander, M. C; Fruchter, A. S; Kann, D. A; Klose, S; Milne, P. A; Williams, G. G; Zheng, W; Hergenrother, C. W; Prochaska, J. X; Prochaska, J.

V; Blake, C; Starr, D; Falco, E. E; Brown, W. R; Dai, X; Deng, J; Xin, L; Qiu, Y; Wei, J; Urata, Y; Nanni, D; Palazzi, E; Greco, G; Bartolini, C; Guarnieri, A; Piccioni, A; Pizzichini, G; Terra, F; Misra, K; Bhatt, B. C; Anupama, G. C; Fan, X; Jiang, L; Wijers, R. A. M. J; Reichart, D. E; Eid, H. A; Bryngelson, G; Puls, J; Goldthwaite, R. C; Hartmann, D. H (The American Astronomical Society, 2008-09)
    We report on multiwavelength observations, ranging from X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the presence of absorption lines due to O I, Si II, and ...
  • Star formation in bulgeless late-type galaxies: clues to their evolution
