WALOP-South: a four camera one shot imaging polarimeter for the PASIPHAE survey. Paper III -- PSF modelling

Indrajit Paul, Kishan Deka, Tuhin Ghosh +22

The two WALOP instruments, built for the PASIPHAE survey, will measure the linear polarization of large numbers of stars in the Galactic polar regions in the SDSS- band. They ar…

TRIShUL: Technique for Reconstructing magnetic Interstellar Structure Using starLight polarization

Namita Uppal, Konstantinos Tassis, Vasiliki Pavlidou +2

We present a novel technique to decompose line-of-sight (LOS) stellar polarization as a function of distance, aimed at reconstructing three dimensional (3D) plane-of-sky (POS) magn…

Evidence for cloud-to-cloud variations in the ratio of polarized thermal dust emission to starlight polarization

Nidhi Mehandiratta, Georgia V. Panopoulou, Eirik Gjerløw +12

The correlation between optical starlight polarization and polarized thermal dust emission can be used to infer intrinsic dust properties. This correlation is quantified by the rat…

Linear polarization study of open clusters towards the anticenter direction: Signature of the spiral arms

Namita Uppal, Shashikiran Ganesh, Vincent Pelgrims +2

Our objective is to investigate the distribution of dust and associated large-scale structures of the Galaxy using optical linear polarization measurements of various open clusters…
