The JCMT BISTRO Survey: Multi-wavelength polarimetry of bright regions in NGC 2071 in the far-infrared/submillimetre range, with POL-2 and HAWC+

L. Fanciullo, F. Kemper, K. Pattle +31

Polarized dust emission is a key tracer in the study of interstellar medium and of star formation. The observed polarization, however, is a product of magnetic field structure, dus…

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…

Revealing the dust grain polarization properties as a function of extinction and distance towards NGC 1893

N. Bijas, Chakali Eswaraiah, Jia-Wei Wang +5

Dust polarization observations at optical wavelengths help to understand the dust grain properties and trace the plane-of-the-sky component of the magnetic field. In this study, we…

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…
