Ultrafast outflows in radio-loud active galactic nuclei [PDF]
, 2014 Recent X-ray observations show absorbing winds with velocities up to mildly-relativistic values of the order of ~0.1c in a limited sample of 6 broad-line radio galaxies. They are observed as blue-shifted Fe XXV-XXVI K-shell absorption lines, similarly to

ChemCatChem, EarlyView.Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.

Late-time Radio Brightening and Emergence of a Radio Jet in the Changing-look AGN 1ES 1927+654
The Astrophysical Journal LettersWe present multifrequency (5–345 GHz) and multiresolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic nuclei (CL-AGNs).

The Radio Structure of the γ-Ray Narrow-line Seyfert 1 Galaxy SDSS J211852.96-073227.5
The Astrophysical Journal, 2023 The γ -ray narrow-line Seyfert 1 (NLS1) galaxies can be considered to be the third class of γ -ray active galactic nuclei possessing relativistic jets. In this paper, we present multi-band high-resolution Very Long Baseline Array (VLBA) images of the γ ...

Significant core shift variability in parsec-scale jets of active galactic nuclei [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The apparent position of jet base (core) in radio-loud active galactic nuclei changes with frequency because of synchrotron self-absorption. Studying this `core shift` effect enables us to reconstruct properties of the jet regions close to the central ...

Advanced Quantum Technologies, EarlyView.Ion implanted donor atom qubits in silicon have demonstrated leading coherence times and gate fidelities. We investigate implantation positional uncertainties with a 40 million silicon atom quantum model based on the atomistic tight‐binding technique.

Optical- and UV-continuum Morphologies of Compact Radio Source Hosts
The Astrophysical JournalWe present the first systematic search for UV signatures from radio source-driven active galactic nuclei (AGN) feedback in Compact Steep Spectrum (CSS) radio galaxies. Owing to their characteristic sub-galactic jets (1–20 kpc projected linear sizes), CSS

Stress‐Induced Reorganization of Proteasomes Through Diffusion and Cytoskeleton‐Dependent Mechanisms
Small, EarlyView.Proteotoxic stress induced by alpha‐synuclein aggregates drives rapid, cytoskeleton‐dependent re‐localization of mammalian proteasomes and formation of transient aggregate‐associated droplets (TAADs). Single‐molecule localization microscopy, light‐sheet imaging, nanopipette injection, single‐cell patch clamp, and single‐particle tracking reveal a ...

Probing the Jet–Torus Interaction in the Radio Galaxy NGC 1052 by Sulfur-bearing Molecules
The Astrophysical Journal, 2023 The radio galaxy NGC 1052 casts absorption features of sulfur-bearing molecules, H _2 S, SO, SO _2 , and CS toward the radio continuum emission from the core and jets.
