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 ...

Modification of bacterial cellulose using silk fibroin β-sheet crystals induced by ultrasonication
Chimica Techno ActaSilk fibroin (SF) has been continuously explored as a biomaterial due to its biocompatibility, tunability, and self-healing properties. In this work, we present a novel approach to the modification of bacterial cellulose (BC) with SF β-sheet dominant ...

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 ...

Magnetic bilayer qubits: A bipartite quantum system
Materials Today AdvancesAn exfoliated monolayer CrI3 possessing the ferromagnetic (FM) nature of out-of-plane Ising spin-up (or spin-down) electrons can be considered as a qubit with a quantum state of |ѱ>=|↑>=|0> (or |ѱ>=|↓>=|1>) due to the theory of the Bloch sphere ...

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 ...

Spectropolarimetry of GRB 180427A: Evidence for Distinct Emission Sites with Varying Polarization
The Astrophysical JournalThe dynamics of the origin of gamma-ray emissions in gamma-ray bursts (GRBs) remains an enigma. Through a joint analysis of GRB 180427A, observed by the Fermi Gamma-ray Space Telescope and AstroSat’s Cadmium Zinc Telluride Imager, we identify emissions ...

Near-ultraviolet Spectropolarimetry as a Tracer of Magnetic Markers of Flux Rope Formation
The Astrophysical JournalWe investigate the suitability of the combined spectral windows of Mg ii h and k and the Fe ii lines around 261 nm as magnetic markers of filament formation.
