  • Head-on collision of spherical galaxies 
    Namboodiri, P. M. S (Astronomical Society of India, 1995)
    N-body simulations of head-on collision of a pair of identical spherical galaxies have been performed with a set of initial conditions covering both merging and non-merging types of collisions. The merging of the galaxies ...
  • N-body simulations of galaxy collisions 
    Namboodiri, P. M. S; Sastry, K. S; Narasimhan, K. S. V. S (Astronomical Society of India, 2001)
    The tidal effects of close collisions between two spherical galaxies of different mass and mass distributions are studied by numerical simulations. The galaxies are represented by polytropes of indices n = 4 and n = 0 which ...
  • On the Formation of Bridges and Tails in Interacting Galaxies - II 
    Namboodiri, P. M. S; Kochhar, R. K; Alladin, S. M (Astronomical Society of Indian, 1987-12)
  • On the formation of tails and bridges in interacting galaxies 
    Namboodiri, P. M. S; Kochhar, R. K (Astronomical Society of India, 1985-12)
    Interacting galaxies produce peculiar feature like tails, bridges, and counterarms of various sizes and shapes. Numerical experiments have been performed to investigate as to how the formation of tails and bridges depends ...
  • Some properties of merger remnants of interacting galaxies modeled as n = 4 polytrope 
    Namboodiri, P. M. S (Astronomical Society of India, 2008-03)
    Galaxies interact in a multitude of ways with their environ- ment. Such interactions can alter the morphological type of galaxies, trigger star formation and even produce active galactic nuclei. One of the important parameter ...
  • Tidal effects on a satellite galaxy influenced by a massive perturber 
    Namboodiri, P. M. S; Cowsik, R; Sugimoto, D (Astronomical Society of India, 2000)
    The tidal influence on a satellite galaxy by a massive perturber is studied by numerical simulations. The satellite is modelled as a non-rotating spherical cluster of uniform density. The perturber is a galaxy described ...
  • Tidal interactions in spherical galaxies 
    Namboodiri, P. M. S (Astronomical Society of India, 2000)
    Numerical simulations of equal mass galaxies, moving initially on a parabolic orbit, have been performed to see how the total energy of the system changes in close and wide encounters. The results are compared with those ...
