  • Vertical scaleheights of stars and gas in the galaxy 
    Narayan, C. A; Jog, C. J (Astronomical Society of India, 2002-09)
    The vertical scaleheight of atomic hydrogen gas is observed to be nearly constant with radius in the inner Galaxy « 8.5 kpc). This has been a long-standing puzzle (Oort 1962) because the gas scaleheight should ...
  • The Very Early Universe: Problems and Perspectives 
    Narlikar, J. V (Astronomical Society of India, 1985-03)
  • Very fast helicity injection leading to critically stable state and large eruptive activity in solar active region NOAA 12673 
    Vemareddy, P (IOP Publishing, 2019-02-20)
    Using the photospheric magnetic and coronal observations of Solar Dynamics Observatory, we studied the buildup and eruption of coronal nonpotential magnetic structure in emerging active region (AR) 12673. The velocity field ...
