The Effect of Bulge Mass on Bar Pattern Speed in Disk Galaxies

Kataria, Sandeep Kumar; Mousumi Das (IOP Publishing, 2019-11)

We present a study of the effect of bulge mass on the evolution of bar pattern speed in isolated disk galaxies using N -body simulations. Earlier studies have shown that disk stars at the inner resonances can transfer a ...
Study of star formation in NGC 1084

Ramya, S; Sahu, D. K; Prabhu, T. P (Blackwell Publishing, 2007-10)

We present UBVRI broad-band, Hα narrow-band photometry of the star-forming complexes in the infrared bright galaxy NGC 1084. Results of medium-resolution spectroscopy of some of the brighter complexes are also discussed. ...
Testing a theoretical prediction for bar formation in galaxies with bulges

Kataria, Sandeep Kumar; Das, Mousumi; Barway, Sudhanshu (EDP Sciences, 2020-08)

Earlier studies have shown that massive bulges impede bar formation in disk galaxies. Recent N-body simulations have derived a bar formation criterion that depends on the radial bulge force in a galaxy disk. We use those ...
