  • 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 ...
  • Near-Infrared and Optical Morphology of the Dusty Galaxy NGC 972 
    Mayya, Y. D; Ravindranath, S; Carrasco, L (The American astronomical Society, 1998-10)
    Near-infrared (NIR) and optical surface photometric analyses of the dusty galaxy NGC 972 are presented. The photometric profiles in the BVRJHK bands can be fitted with a combination of Gaussian and exponential profiles, ...
  • Study of the emission line spectra and the stellar populations of starburst galaxies 
    Ravindranath, S; Prabhu, T. P (Astronomical Society of India, 2000)
    Based on the optical-NIR spectra, we discuss the nebular properties and stellar populations of starburst nuclei. Starbursts are found to have higher electron densities and higher excitations compared to HII nuclei. We find ...
  • A Study of the Emission-Line Spectra and the Stellar Populations of Starburst Galaxies 
    Ravindranath, S; Prabhu, T. P (Springer, 2001-03)
    Based on optical-NIR spectra, we discuss the nebular properties and stellar populations of starburst nuclei. Starbursts are found to have higher electron densities and higher excitations than HII nuclei. The emission lines ...
