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…

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…
