Multiband Spectropolarimetry of Lunar Maria, Pyroclastics, Fresh Craters, and Swirl Materials
The Astronomical JournalImaging polarimetry is a well-known method for examining the small-scale structure of the surface regolith of airless celestial bodies. In this study, we examine (for the first time) the wavelength-dependent polarization behavior of selected lunar areas,

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 Polarimetric Observations of the Western Hotspot of Pictor A
The Astrophysical Journal LettersWe present the results of the analysis of a ∼2 Msec spectropolarimetric observation of the western hotspot (WHS) of the radio galaxy Pictor A. This is the brightest extragalactic radio source that allows us to carry out spatially resolved observations ...

Origin of Line Broadening in Fading Granules: Influence of Small-scale Turbulence
The Astrophysical JournalIn the quiet region of the solar photosphere, turbulent convective motions of the granular flows naturally drive the subgranular-scale flows. However, evaluating such small-scale velocities is challenging because of the limited instrumental resolution ...

Optical spectropolarimetry of extreme Hα line profiles in seven active galactic nuclei
Astronomy & AstrophysicsContext. Some active galactic nuclei (AGNs) are known to show extremely asymmetric broad Balmer lines, with their main peak redshifted or blueshifted by thousands of km s−1, severely challenging our understanding of the standard AGN paradigm. Aims.

Using the Hanle Effect in Mg ii k to Quantify the Open Flux above the Solar Poles
The Astrophysical JournalWe test the use of the Mg ii resonant lines for measurement of the magnetic field at the top of the chromosphere of polar coronal holes (CHs). The Hanle effect in the core of Mg II k enables access to a regime of field strengths where the Zeeman effect ...
