Co-evolution of bar and spiral arms in TNG50 simulations using Information Theory
Anagha A G, Arunima Banerjee
Using Information Theory, we investigate the co-evolution of bars and spiral arms in barred-spiral galaxies from the cosmological magneto-hydrodynamic Illustris TNG50 simulations.…

Are purely gaseous bars in dwarf-irregulars a myth?
Anagha A G, Arunima Banerjee
About two-thirds of the galactic disks exhibit a central ellipsoidal stellar component called the bar, with or without a gaseous counterpart. However, there are a few dwarf galaxie…

How does a low surface brightness galaxy form spiral arms?
Ganesh Narayanan, Anagha A. G., Arunima Banerjee
The formation and evolution of spiral arms in low surface brightness galaxies (LSBs) are not well-understood. We study the dynamics of spiral arms in two prototypical LSBs, F568-VI…
