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…
Analyzing the cosmic architecture in the vicinity of Grand-design and Flocculent spiral galaxies with Local Geometric Index
Suman Sarkar, Ganesh Narayanan, Arunima Banerjee
We explore the environment of 351 grand-design and 541 flocculent spiral galaxies recently identified employing convolutional neural networks from the data release of Slo…
