Galaxy interactions in filaments and sheets: effects of the large-scale structures versus the local density
Apashanka Das, Biswajit Pandey, Suman Sarkar
The major interactions are known to trigger star formation in galaxies and alter their colour. We study the major interactions in filaments and sheets using the SDSS data to unders…
The maximum extent of the filaments and sheets in the cosmic web: an analysis of the SDSS DR17
Prakash Sarkar, Biswajit Pandey, Suman Sarkar
Filaments and sheets are striking visual patterns in cosmic web. The maximum extent of these large-scale structures are difficult to determine due to their structural variety and c…
Do minor interactions trigger star formation in galaxy pairs?
Apashanka Das, Biswajit Pandey, Suman Sarkar
We analyze the galaxy pairs in a set of volume limited samples from the SDSS to study the effects of minor interactions on the star formation rate (SFR) and colour of galaxies. We…
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…
