Polarization geometry of magnetohydrodynamic turbulence
Raphael Skalidis
We introduce a geometric framework that organizes the second-order statistics of the Elasser fields into polarization states on generalized Poincaré spheres. In this representatio…
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 paper presents a polar shapelet‑based method for modeling the point spread function of the WALOP‑South wide‑field imaging polarimeter, achieving ~0.15% photometric accuracy for…
The multiphase interstellar medium as a common origin for magnetic misalignment and TB parity violation
Andrea Bracco, Ari J. Cukierman, Raphael Skalidis +1
We present an original data analysis and a physical model that provide new insights into the origin of, and relationship between, two observables of the dusty, polarized Galaxy at…
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…
Microphysical Regulation of Non-Ideal MHD in Weakly-Ionized Systems: Does the Hall Effect Matter?
Philip F. Hopkins, Jonathan Squire, Raphael Skalidis +1
The magnetohydrodynamics (MHD) equations plus 'non-ideal' (Ohmic, Hall, ambipolar) resistivities are widely used to model weakly-ionized astrophysical systems. We show that if grad…
Investigating the role of magnetic fields in the formation and evolution of striations in interstellar clouds with PRIMA
Raphael Skalidis, Konstantinos Tassis, Aris Tritsis +1
Striations are diffuse, linear, quasi-periodic, and magnetized structures located in the outskirts of molecular clouds. These structures seem to play an important role during the e…
