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…
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…
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…
\HI{} 21cm observations and dynamical modelling of the thinnest galaxy: FGC 2366
K. Aditya, Arunima Banerjee, Peter Kamphuis +3
Superthin galaxies are bulgeless low surface brightness galaxies with unusually high major-to-minor axes ratio of the stellar disc, i.e.,. We present Giant Metrewave Rad…
Analyzing the cosmic web environment in the vicinity of grand-design and flocculent spirals with local geometric index
Suman Sarkar, Ganesh Narayanan, Arunima Banerjee
We explore the environment of a combined set of grand-design and flocculent spiral galaxies. We introduce a novel estimator called the \textit{local geometric index} to…
