  • Distribution of stars perpendicular to the plane of the Galaxy 
    Chatterjee, S (Indian Academy of Sciences, 1991-12)
    A detailed calculation is given of the distribution of mass above the Galactic plane for any arbitrary mass distribution and velocity distribution. It is shown that an analytic expression can be found for the gravitational ...
  • Energy enigmas in the early universe and related problems in Newtonian cosmology 
    Sivaram, C (Springer, 1988-01)
    Some paradoxical situations regarding the balance between the different forms of energy present and the velocities of expansion in the early stages of the big bang are discussed. Solutions are suggested in the framework ...
  • Flat rotation curves: A result of the helical inverse cascade in turbulent media? 
    Prabhu, R. D; Krishan, V (The American Physical Society, 1994-06)
    We have modeled the rotation curves of 21 galaxies observed by Amram et al. (1992), by combining the effects of rigid rotation, gravity, and turbulence. The main motivation behind such modeling is to study the formation ...
  • Nonlinear curvature Lagrangians and extended inflation in the early universe 
    Sivaram, C; Campanelli, M (Springer, 1992-08)
    Theories with Lagrangians nonlinear in the curvature scalar can be reduced by appropriate transformations to a form similar to the Brans-Dicke model. This may enable us to have extended inflation in the early universe ...
  • On structure formation in the universe 
    Satya Narayanan, A (Springer, 1994-12)
    The formation of structures in the universe is one of the most challenging problems of cosmology. In this paper, an attempt to explain the formation of galaxies through the generation of vortices (with dissipation) in an ...
