  • Classification of ultraviolet stellar spectra using artificial neural networks 
    Gulati, R. K; Gupta, R; Gothoskar, P; Khobragade, S (Astronomical Society of India, 1996)
    Scheme based on the artificial neural networks (ANNs) trained with multi-layer back propagation using single level network for classifying ultraviolet spectra in the IUE Low-Dispersion Spectra Reference Atlas is presented. ...
  • Extragalactic star formation rate -- estimates at different wavelengths 
    Prabhu, T. P (Astronomical Society of India, 2012)
    The star formation rate (SFR) in galaxies is of prime importance in the study of formation and evolution of galaxies. Different methods have hence been evolved to estimate the current SFR in galaxies, using indicators at ...
  • Star formation in blue compact dwarf Galaxies 
    Ramya, S; Prabhu, T. P; Sahu, D. K (Astronomical Society of India, 2012)
    Blue compact dwarf galaxies (BCDGs) are dwarfs undergoing current burst of star formation (SF). In our work, we determine the ages of the underlying old stellar population to be ∼4 Gyr that is dominating the mass of the ...
