AGN Feedback Signatures in UV Emission
GalaxiesSupermassive black holes (SMBH) are believed to influence galaxy evolution through AGN (active galactic nuclei) feedback. Galaxy mergers are key processes of galaxy formation that lead to AGN activity and star formation.

Subarcsecond-resolution Imaging of M51 with the International LOFAR Telescope
The Astrophysical Journal, 2023 We present an International LOFAR Telescope (ILT) subarcsecond-resolution image of the nearby galaxy M51 with a beam size of 0.″436 × 0.″366 and rms of 46 μ Jy. We compare this image with a European VLBI Network study of M51 and discuss the supernovae in

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase
Advanced Science, EarlyView.Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

A Comprehensive Observational Study of the FRB 121102 Persistent Radio Source
The Astrophysical Journal, 2023 FRB 121102 is the first fast radio burst to be spatially associated with a persistent radio source (QRS 121102), the nature of which remains unknown. We constrain the physical size of QRS 121102 by measuring its flux-density variability with the VLA from

Advanced Science, EarlyView.Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

Here Be SDRAGNs—Spiral Galaxies Hosting Large Double Radio Sources
The Astronomical JournalWe present a sample of large double radio sources hosted by spiral galaxies (spiral double radio active galactic nuclei, SDRAGNs). Candidates were initially selected through the Radio Galaxy Zoo project and subsequently refined using Sloan Digital Sky ...

An Extended Lyα Outflow from a Radio Galaxy at z = 3.7?
The Astrophysical Journal Letters, 2023 Spatially resolved observations of active galactic nuclei (AGN) host galaxies undergoing feedback processes are one of the most relevant avenues through which galactic evolution can be studied, given the long-lasting effects AGN feedback has on gas ...

Constraining the Redshift Evolution of FIRST Radio Sources in RCS1 Galaxy Clusters
, 2010 We conduct a statistical analysis of the radio source population in galaxy clusters as a function of redshift by matching radio sources from the Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) catalog with 618 optically-selected galaxy ...
