Context. We investigate non-Zeeman circular polarization and linear polarization levels of up to 1% of 12CO spectral line emission detected in a shocked molecular clump around the supernova remnant (SNR) IC 443, with the goal of understanding the magnetic field structure in this source. Aims. We examine our polarization results to confirm that the circular polarization signal in CO lines is cau...

We report first-epoch circular polarization results for 133 active galactic nuclei in the MOJAVE program to monitor the structure and polarization of a flux limited sample of extra-galactic radio jets with the VLBA at 15 GHz. We found strong circular polarization (≥ 0.3%) in approximately 15% of our sample. The circular polarization was usually associated with jet cores; however, we did find a ...

Properties of circularly polarized waves are studied in the pulsar magnetosphere plasma. It is shown that some observational characteristics of the circular polarization observed in the pulsar radio emission can be qualitatively explained in the framework of the model based on anomalous Doppler resonance. Performed analysis provides that if the difference between Lorentz factors of electrons an...

Dynamical control of terahertz metadevices and integration versatile functions are highly desired due to increasing practical demands. Here, we propose a multifunctional photosensitive Si hybrid metastructure consisting twisted split-ring resonator pairs that could empower multi-state polarization switching object-recognized imaging. The theoretical simulated results show inverse complete modul...

Tashenov1,2 1GSI, Darmstadt, Germany; 2Stockholm University, AlbaNova University Center, Roslagstullsbacken 21, SE-10691 Stockholm, Sweden Photon helicity a projection of the photon spin on its momentum direction, also called circular polarization, can provide information about processes in which angular momentum and spin interactions play an important role. In particular it can be used in a...

We present circular polarization results from a 5 GHz survey of the parsec-scale polarization properties of 40 AGN made with the VLBA. We find 11 circular polarization detections at the 3σ level or higher. This nearly quadruples the number of sources detected in circular polarization at VLBI resolution. We find no correlation between fractional linear and circular polarization across our sample...

We generate angularly isolated beams of circularly polarized extreme ultraviolet light through the first implementation of non-collinear high harmonic generation with circularly polarized driving lasers. This non-collinear technique offers numerous advantages over previous methods, including the generation of higher photon energies, the separation of the harmonics from the pump beam, the produc...

We present multi-frequency, high resolution VLBA circular polarization images of the radio source 3C 84 in the center of NGC 1275. Our images reveal a complex distribution of circular polarization in the inner parsec of the radio jet, with local levels exceeding 3% polarization, the highest yet detected with VLBI techniques. The circular polarization changes sign along the jet, making 3C 84 als...

Abstract This paper builds on the machine learning research to propose two new algorithms based optimizing Adaptive Neuro Fuzzy Inference System (ANFIS) with a dual-polarization antenna predict pseudorange errors by considering multiple variables including right-hand circular polarized (RHCP) signal strength, strength difference between left-hand (LHCP) and RHCP outputs, satellites’ el...
