  • Mapping of the Orion molecular cloud in the [CII] line and continuum at 158 μm 
    Mookerjea, B; Ghosh, S. K; Kaneda, H; Nakagawa, T; Ojha, D. K; Rengarajan, T. N; Shibai, H; Verma, R. P (Astronomical Society of India, 2001)
    A fabry Perot Spectrometer (FPS) tuned to the astrophysically interesting (CII) line at 157.7409 µm, developed at ISAS (Japan) has been successfully interfaced to the TIFR 100 cm far-infrared balloon borne telescope. A ...
  • Mid-infrared observations of three compact HII regions and PAH emission 
    Verma, R. P; Ghosh, S. K; Karnik, A. D; Mookerjea, B; Rengarajan, T. N (Astronomical Society of India, 1999)
  • Modelling infrared spectra of a few compact HII regions 
    Ghosh, S. K; Verma, R. P (Astronomical Society of India, 1999)
    The observed near infrared to sub-mm spectra of five compact HII regions, viz., IRAS 18116-1646, 18162-2048, 19422+2427, 22308+5812 and 18434-0242, consisting of the continuum as well as several features, have been explained ...
  • A Multiwavelength Study of the Galactic Star Forming Region Associated with IRAS 20255+3712 / S 106 
    Ghosh, S. K; Kulkarni, V. K; Ojha, D. K; Verma, R. P (Astronomical Society of India, 2003)
    The Galactic star forming region associated with IRAS 20255+3712 / S 106 has been mapped simultaneously in 150 and 210 μm bands using the TIFR 1-metre balloon borne far-infrared (FIR) telescope with an angular resolution ...
  • 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 ...
  • Optical identification of equatorial infrared catalogue number 1 sources previously identified with only AFGL sources 
    Iyengar, K. V. K; Tandon, S. N; Verma, R. P (Astronomical Society of India, 1983-09)
    We have identified, using Palomar Observatory Sky Survey (POSS) prints, the optical counterparts of six of the seven sources from the Equatorial Infrared Catalogue Number 1 (EIC-1) previously identified by Sweeney et al. ...
  • Post-outburst phase of McNeil's nebula (V1647 Orionis) 
    Ojha, D. K; Ghosh, S. K; Tej, A; Verma, R. P; Vig, S; Anupama, G. C; Sahu, D. K; Parihar, P. S; Bhatt, B. C; Prabhu, T. P; Maheswar, G; Bhatt, H. C; Anandarao, B. G; Venkataraman, V (Blackwell Publishing, 2006-03)
    We present a detailed study of the post-outburst phase of McNeil's nebula (V1647 Orionis) using optical B, V, R, I and near-infrared (NIR) J, H, K photometric and low-resolution optical spectroscopic observations. The ...
  • Simultaneous infrared and H-alpha measurements of Be stars 
    Apparao, K. M. V; Tarafdar, S. P; Verma, R. P; Iyengar, K. V. K; Ghosh, K. K (Indian Academy of Sciences, 1993)
    The observed infrared excess in Be stars is usually interpreted as free-free and free-bound emission from a hot gas envelope around the Be star. This hot gas should also emit H-alpha line radiation. Earlier observations ...
  • A Study of the Galactic Star Forming Region IRAS 02593+6016 / S 201 in Infrared and Radio Wavelengths 
    Ojha, D. K; Ghosh, S. K; Kulkarni, V. K; Testi, L; Verma, R. P; Vig, S (Astronomical Society of India, 2003)
    We present infrared and radio observations of IRAS 02593+6016 / S 201 star forming region. A young star cluster is observed in this region, which contains different classes of young stellar objects. The near-infrared (NIR) ...
  • A two band far-infrared photometer with bolometer arrays 
    Verma, R. P; Rengarajan, T. N; Ghosh, S. K (Astronomical Society of India, 1993)
    A new two band photometer for the Tata Institute of Fundamental Research (TIFR) 1m balloon-borne telescope is described. The detector system consists of two arrays (of six detectors each) of liquid He-3 cooled bolometers. ...
