Identifying lopsidedness in spiral galaxies using a Deep Convolutional Neural Network
Biju Saha, Suman Sarkar, Arunima Banerjee
About 30\% of disk galaxies show lopsidedness in their stellar disk. Although such a large-scale asymmetry in the disk can be primarily looked upon as a long-lived mode (), th…

Can fractal dimension distinguish between grand-design and flocculent spiral arms?
Biju Saha, Subhadip Dutta, Arunima Banerjee
About two-thirds of disk galaxies host spiral arms, ranging from well-delineated grand-design spirals to fragmented flocculent spiral galaxies. We introduce fractal dimension …
