Evolution of low surface brightness ultra-thin galaxies: The role of dark matter halo and bar formation on disk thickness
K. Aditya, Arunima Banerjee
We investigate how stellar disks sustain their ultrathin structure throughout their evolution. We follow the evolution of ultrathin stellar disks with varying dark matter (DM) halo…

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…

The dynamical lineage of field ultra-diffuse galaxies
Nilanjana Nandi, Arunima Banerjee, Ganesh Narayanan
Ultra-diffuse galaxies (UDGs) exhibit morphological similarities with other low-luminosity galaxies indicating a possible evolutionary connection. We investigate for common dynamic…
