  • Massive Star Formation in the Infrared-bright Galaxy NGC 972 
    Ravindranath, S; Prabhu, T. P (The American Astronomical Society, 1998-06)
    We present the results of optical broadband and Hα imaging studies of the infrared-bright galaxy NGC 972. The broadband images and B/R color map reveal the peculiar morphology and complex dust distribution. Massive star ...
  • Measurements of 220 GHz atmospheric transparency at IAO, Hanle, during 2000-2003 
    Ananthasubramanian, P. G; Yamamoto, S; Prabhu, T. P; Angchuk, D (Astronomical Society of India, 2004-06)
    A 220 GHz tipping radiometer was installed at the Indian Astronomical Observatory (IAO), Hanle (Latitude 32o46'46" N; Longitude 78o57'51" E; Altitude 4500 m, above msl) towards the end of December 1999. The system is in ...
  • Mildly Active Nuclei of Galaxies 
    Prabhu, T. P (Indian Academy of Sciences, 1985)
    Milder forms of activity in the nuclear regions of galaxies are reviewed. Three classes of activity are identified, namely starbursts, high-excitation emission-line and low-ionization emission-line nuclei. Sérsic perinuclear ...
  • Modelling the synchrotron light curves in recurrent novae V745 Scorpii and RS Ophiuchi 
    Kantharia, N. G; Dutta, P; Roy, N; Anupama, G. C; Chitale, A; Ishwara-Chandra, C; Prabhu, T. P; Ashok, N. M; Banerjee, D. P. K (Astronomical Society of India, 2015-02)
    In this paper, we present the synchrotron light curve at 610 MHz from the recurrent nova V745 Sco following its outburst on 6 February 2014. The system has been detected and periodically monitored with the Giant Metrewave ...
  • Multi-frequency, multi-epoch study of MrK 501: hints for a two-component nature of the emission 
    Shukla, A; Chitnis, V. R; Singh, B. B; Acharya, B. S; Anupama, G. C; Bhattacharjee, P; Britto, R. J; Mannheim, K; Prabhu, T. P; Saha, L; Vishwanath, P. R (IOP Publishing, 2015-01-01)
    Since the detection of very high energy (VHE) γ -rays from Mrk 501, its broadband emission of radiation was mostly and quite effectively modeled using the one zone emission scenario. However, broadband spectral and flux ...
  • A multiwavelength study of the massive star-forming region IRAS 06055+2039 (RAFGL 5179) 
    Tej, A; Ojha, D. K; Ghosh, S. K; Kulkarni, V. K; Verma, R. P; Vig, S; Prabhu, T. P (EDP Sciences, 2006-06)
    Aims.We present a multiwavelength study of the massive star-forming region associated with IRAS 06055+2039. Methods.Narrow-band near-infrared (NIR) observations were carried out with UKIRT-UFTI in molecular hydrogen and ...
  • Multiwavelength study of the TeV blazar Mrk 421 during a giant flare 
    Shukla, A; Chitnis, V. R; Vishwanath, P. R; Acharya, B. S; Anupama, G. C; Bhattacharjee, P; Britto, R. J; Prabhu, T. P; Saha, L; Singh, B. B (EDP Sciences, 2012-05)
    Aims. The nearby (z = 0.031) TeV blazar Mrk 421 was reported to be in a high state of flux activity since November, 2009. We aim to investigate possible changes in the physical parameters of Mrk 421 during its high state ...
  • The Nebular Remnant and Quiescent Spectrum of Nova Gk-Persei 
    Anupama, G. C; Prabhu, T. P (Royal Astronomical Society, 1993-07-15)
    CCD images of the nebular shell of the old nova GK Per in [N II] and [O III] emission lines, and also the quiescent spectrum in the optical region, are presented. Proper motion measurements of the knots in [N II]over the ...
  • Night sky at the Indian Astronomical Observatory during 2000-2008 
    Stalin, C. S; Hegde, M; Sahu, D. K; Parihar, P. S; Anupama, G. C; Bhatt, B. C; Prabhu, T. P (Astronomical Society of India, 2008-09)
    This paper presents an analysis of the optical night sky brightness and extinction coefficient measurements in UBVRI at the Indian Astronomical Observatory (IAO), Hanle, during the period 2000–2008. They are obtained from ...
  • Night Sky Extinction Measurements at the Indian Astronomical Observatory, Hanle 
    Parihar, P. S; Sahu, D. K; Bhatt, B. C; Subramaniam, A; Anupama, G. C; Prabhu, T. P (Astronomical Society of India, 2003)
    We present the estimates of the night sky extinction at the Indian Astronomical Observatory. Also presented are the estimates of the night sky brightness. The extinction in the U band at IAO is found to be lower than the ...
