Quantifying the influence of bars on action-based dynamical modelling of disc galaxies
Soumavo Ghosh, Wilma H. Trick, Gregory M. Green
Action-based dynamical modelling, using stars as dynamical tracers, is an excellent diagnostic to estimate the underlying axisymmetric matter distribution of the Milky Way. However…
Bars and boxy/peanut bulges in thin and thick discs. II. Can bars form in hot thick discs?
Soumavo Ghosh, Francesca Fragkoudi, Paola Di Matteo +1
The Milky Way as well as a majority of external galaxies possess a thick disc. However, the dynamical role of the (geometrically) thick disc on the bar formation and evolution is n…
The pattern speeds of vertical breathing waves
Tigran Khachaturyants, Victor P. Debattista, Soumavo Ghosh +2
We measure and compare the pattern speeds of vertical breathing, vertical bending, and spiral density waves in two isolated N-body+SPH simulations, using windowed Fourier transform…
Excitation of vertical breathing motion in disc galaxies by tidally-induced spirals in fly-by interactions
Ankit Kumar, Soumavo Ghosh, Sandeep Kumar Kataria +2
It is now clear that the stars in the Solar neighbourhood display large-scale coherent vertical breathing motions. At the same time, Milky Way-like galaxies experience tidal intera…
