The Effect of Dark Matter Halo Shape on Bar Buckling and Boxy/Peanut Bulges
Ankit Kumar, Mousumi Das, Sandeep Kumar Kataria
It is well established that bars evolve significantly after they form in galaxy discs, often changing shape both in and out of the disc plane. In some cases they may bend or buckle…
Galaxy Flybys: Evolution of the Bulge, Disk, and Spiral Arms
Ankit Kumar, Mousumi Das, Sandeep Kumar Kataria
Galaxy flybys are as common as mergers in low redshift universe and are important for galaxy evolution as they involve the exchange of significant amounts of mass and energy. In th…
Testing a theoretical prediction for bar formation in galaxies with bulges
Sandeep Kumar Kataria, Mousumi Das, Sudhanshu Barway
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 bu…
Can Bars Erode Cuspy Halos ?
Sandeep Kumar Kataria, Mousumi Das, Stacy McGaugh
One of the major and widely known small scale problem with the Lambda CDM model of cosmology is the core-cusp problem. In this study we investigate whether this problem can be reso…
The Effect of Bulge Mass on Bar Pattern Speed in Disk Galaxies
Sandeep Kumar Kataria, Mousumi Das
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…
A Study of the Effect of Bulges on Bar Formation in Disk galaxies
Sandeep Kumar Kataria, Mousumi Das
We use N-body simulations of bar formation in isolated galaxies to study the effect of bulge mass and bulge concentration on bar formation. Bars are global disk instabilities that…
