An Embedded active nucleus in the OH megamaser galaxy IRAS 16399-0937

Sales, Dinalva A; Robinson, A; Axon, D. J; Gallimore, J; Kharb, P; Curran, R. L; O'Dea, C.; Baum, S; Elitzur, M; Mittal, R (IOP Publishing Ltd, 2015-01-20)

We present a multiwavelength study of the OH megamaser galaxy IRAS16399–0937, based on new Hubble Space Telescope (HST)/Advanced Camera for Surveys F814W and Hα+[N II] images and archive data from HST, Two Micron All Sky ...
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 ...
Tidal disruption model for the interacting pair of galaxies VV 117 (NGC 2444/45)

Narasimhan, K. S. V. S; Namboodiri, P. M. S; Alladin, S. M (Springer, 2003-09)

A series of N-body simulations have been performed to interpret the interacting pair of galaxies VV 117 (NGC 2444/45). The galaxies have been modelled assuming a mass ratio two. The simulations use various values for the ...
