  • The Density Structure of a Galaxy Influenced by a Massive Companion 
    Namboodiri, P. M. S; Kochhar, R. K (Royal Astronomical Society, 1993-04-15)
    The tidal influence of a massive galaxy on a non-rotating spherical companion is studied using numerical simulations. The simulations use various values of mass ratio and velocity of collision while the pericentric distance ...
  • Energy and angular momentum transfer in binary galaxies 
    Namboodiri, P. M. S; Kochhar, R. K (NASA, 1990-11)
    The authors numerically studied tidal effects of a massive perturber on a satellite galaxy. The model consists of a spherical satellite galaxy and a point mass perturber and the encounter is non-penetrating. A wide range ...
  • Energy exchange during collision of a pair of disc-sphere galaxies 
    Namboodiri, P. M. S; Kochhar, R. K (Kluwer Academic Publishers, 1989-02)
    We have considered the collision of a pair of disc-sphere galaxies under the impulsive approximation to study the variation of the energy change of the disc due to the passage of a spherical galaxy. Various collision ...
  • Galaxy dynamics with small computers: Some results on tidal interactions. 
    Kochhar, R. K; Namboodiri, P. M. S (Springer Netherlands, 1995-06)
    Numerical simulations with a small computer have been performed to investigate the tidal influence of a larger galaxy on a smaller companion. A criterion is developed for disruption of the satellite galaxy. The behaviour ...
  • Head-on collision of disk-sphere galaxies 
    Namboodiri, P. M. S; Sastry, K. S; Narasimhan, K. S. V. S (2006-02)
    Numerical simulations are performed to study the tidal effects of non-merging rapid head-on collision between a disk galaxy and a spherical galaxy. The disk consists of three components – a disk, a bulge and a halo – and ...
  • 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 ...
  • Influence of variable permeability on combined free and forced convection about inclined surfaces in porous media 
    Chandrasekhara, B. C; Namboodiri, P. M. S (Elsevier, 1985-01)
    The analysis is carried out for mixed convection about inclined surfaces in a saturated porous media incorporating the variation of permeability and thermal conductivity due to packing of particles. Similarity solutions ...
  • Mathematical sciences: The dynamics of Colliding Galaxies 
    Namboodiri, P. M. S (2006-01)
    Galaxies interact in a multitude of ways with their environment. Such interactions can alter the morphological type of galaxies, trigger star formation and even produce active galactic nuclei. During the past three decades ...
  • N-Body Simulation of a Deeply Penetrating Collision Between Unequal Galaxies 
    Namboodiri, P. M. S; Sastry, K. S; Narasimhan, K. S. V. S (Kluwer Academic Publishers, 1998-09)
    We study the tidal effects of a deeply penetrating collision between two spherical galaxies, one twice massive but less dense than the other, by numerical simulations. We consider the relative motion of the galaxies to be ...
  • 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 ...
  • On the tidal disruption of a spherical galaxy 
    Namboodiri, P. M. S; Kochhar, R. K (Blackwell Publishing, 1991-12)
    The disruption of a satellite galaxy as it undergoes collision with a massive perturber is investigated by numerical simulations. The models are restricted by a constant pericentric distance. The disruption of the satellite ...
  • Oscillations In Galaxies 
    Namboodiri, P. M. S (Springer, 2000-02)
    Oscillations in galaxies have been investigated by numerical simulations. The various models used have density distributions corresponding to that of polytrope of index n in the range 0 ≤ n ≤ 4 and their evolution has been ...

    Anosova, J; Namboodiri, P. M. S; Deshpande, M. R (Astronomical Society of the Pacific, 1996)
  • The relaxation time in spherical galaxy simulations 
    Namboodiri, P. M. S (International Astronomical Union, 2003)
    The relaxation time of a spherical galaxy with various density distributions has been evaluated using numerical simulations. The results indicate that the relaxation time is weakly dependent on the density of the galaxies ...
