Spectropolarimetry of SN2010jl

, 2019
SN 2010jl is one of the brightest SNe type Iln ever detected in all energy bands, due to a strong circumstellar medium interaction. With a distance of ~ 40 Mpc and absolute magnitude of Mₚₑₐₖ≈—20.5, SN2010jl is one of the best-studied examples of the Iln class from Radio to X-rays bands to date.

X-Ray Polarization Study of the Neutron Star Low-mass X-Ray Binary GX 349+2

The Astrophysical Journal
We report the first X-ray polarimetric results of the neutron star (NS) low-mass X-ray binary Z-source GX 349+2 using the Imaging X-ray Polarimetry Explorer (IXPE). We discovered that the X-ray source was polarized at a polarization degree of PD = 1.1% ±

Discovery of Variable Polarization in the Hα Profile of the Symbiotic Star Y Gem: A Case for Orbital-phase-dependent Variation in Raman-scattered Lyβ Emission

The Astrophysical Journal
The geometry and morphology of symbiotic stars (SySts) are conducive to a variety of scattering phenomena. Among the most prominent is the Raman scattering of the O VI doublet λλ 1032, 1038, which often shows strongly polarized features in the visible ...

Spectropolarimetry of Seyfert nuclei

The Astrophysical Journal, 1985
The present optical spectropolarimetry of six strongly polarized type 1 and 2 Seyfert nuclei, with a spectral resolution of about 10 A and a typical coverage of 3300-7100 A, facilitates comparisons of polarization between various permitted and forbidden emission lines and the continuum.

Energy-dependent Polarization Angle Variability as a Robust Diagnostic for Blazar Flaring Mechanisms

The Astrophysical Journal
Identifying the physical mechanism driving blazar flares remains a central challenge in high-energy astrophysics. We show that the energy dependence of the standard deviation of the polarization angle variability ( σ _PA ) provides a powerful and robust ...
