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…

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…

Identification of Grand-design and Flocculent Spirals from SDSS using Convolutional Neural network

Suman Sarkar, Ganesh Narayanan, Arunima Banerjee +1

Spiral galaxies can be classified into the {\it Grand-designs} and {\it Flocculents} based on the nature of their spiral arms. The {\it Grand-designs} exhibit almost continuous and…

Are superthin galaxies low surface brightness galaxies seen edge-on? The star formation probe

Ganesh Narayanan, Arunima Banerjee

Superthin galaxies (STs) are edge-on disc galaxies with strikingly high planar-to-vertical axes ratios of with no bulge component, and central surface brightness in…
