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

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis
Plant, Cell &Environment, Volume 49, Issue 9, Page 7191-7209, September 2026.ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

Active Galactic Nuclei, Radio Jets and Acceleration of UHECRs [PDF]
Nuclear Physics B - Proceedings Supplements, 2009 We present the general properties of the Active Galactic Nuclei (AGNs) and discuss the origin and structure of jets that are associated to a fraction of these objects. We then we address the problems of particle acceleration at highly relativistic energies and set limits on the luminosity of AGN jets for being origin of UHECRs.

The First Triple Radio Active Galactic Nucleus in an Ongoing Galaxy Merger
The Astrophysical Journal LettersGalaxy mergers are predicted to be a critical stage of merger-driven SMBH growth and galaxy evolution. Systems exhibiting multiple active galactic nuclei (AGN) are an important observational tool for constraining the prevalence and properties of merging ...

Origin of radio emission from nearby low-luminosity active galactic nuclei
, 2005 We use the observational data in radio, optical, and X-ray wave bands for a sample of active galactic nuclei (AGNs) with measured black hole masses to explore the origin of radio emission from nearby low-luminosity active galactic nuclei (LLAGNs).

core
The Astrophysical Journal3C 264 is one of the few FRI radio galaxies with detected TeV emission. It is a low-luminosity active galactic nucleus (LLAGN) and is generally associated with a radiatively inefficient accretion flow (RIAF).

Are X-Ray Atmospheres Heated by Turbulent Dissipation? XRISM Constraints
The Astrophysical JournalWe evaluate whether dissipation of turbulence injected into hot cluster atmospheres by jets and bubbles can offset radiative cooling flows. No trends are found between atmospheric velocity dispersion, σ _v , and either the ratio of kinetic to thermal ...

Deep Learning‐Assisted Coherent Raman Scattering Microscopy
Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Probing galaxy evolution below the noise threshold with radio observations [PDF]
, 2020 Philosophiae Doctor - PhDThe faint radio population consisting of star forming galaxies (SFG) and radio-quiet active galactic nuclei (AGN) is important in the study of galaxy evolution.

VLA FRAMEx. I. Wideband Radio Properties of the AGN in NGC 4388
The Astrophysical JournalWe present the first results from Karl G. Jansky Very Large Array (VLA) observations as a part of the Fundamental Reference Active Galactic Nucleus (AGN) Monitoring Experiment, a program to understand the relationship between AGN accretion physics and ...
