Changing-Look AGNs or Short-Lived Radio Sources?
Frontiers in Astronomy and Space Sciences, 2017 The evolution of extragalactic radio sources has been a fundamental problem in the study of active galactic nuclei for many years. A standard evolutionary model has been created based on observations of a wide range of radio sources.

Radio Spectroscopy of Active Galactic Nuclei
, 2005 Radio spectroscopy offers a number of tools for studying a large variety of astrophysical phenomena, ranging from stars and their environment to interstellar and intergalactic medium, active galactic nuclei (AGN) and distant quasars. Main targets of extragalactic radio spectroscopy are atomic and molecular material in galaxies, HII regions, and maser ...

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 ...

Chemogenetic Activation of G12 Signaling Thickens the Epidermis With Enhanced Barrier Function
FASEB BioAdvances, Volume 8, Issue 8, August 2026.In this study, we investigated the role of G12 signaling in the epidermis using a keratinocyte‐specific chemogenetic approach. Activation of G12 signaling promoted keratinocyte differentiation and enhanced epidermal barrier function by upregulating filaggrin, claudin‐1, and ceramide.

On the Jet Properties of γ-Ray-loud Active Galactic Nuclei [PDF]
, 2018 Based on broadband spectral energy distributions (SEDs), we estimate the jet physical parameters of 1392 γ-ray-loud active galactic nuclei (AGNs), the largest sample so far. The (SED) jet power and magnetization parameter are derived for these AGNs.

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.

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

RADIO-SELECTED BINARY ACTIVE GALACTIC NUCLEI FROM THE VERY LARGE ARRAY STRIPE 82 SURVEY [PDF]
, 2014 Galaxy mergers play an important role in the growth of galaxies and their supermassive black holes. Simulations suggest that tidal interactions could enhance black hole accretion, which can be tested by the fraction of binary active galactic nuclei (AGNs)
