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).

The Innermost Regions of Active Galactic Nuclei – From Radio to X-rays [PDF]
, 2007 Active Galactic Nuclei (AGN) can be probed by at different regions of the electromagnetic spectrum: e.g., radio observations reveal the nature of their relativistic jets and their magnetic fields, and complementarily, X-ray observations give insight into the changes in the accretion disk flows.

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems
Advanced Science, Volume 13, Issue 42, 28 July 2026.A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

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 ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract The 2021–2022 Fukushima‐Oki earthquakes in northeastern Japan provide a valuable opportunity to deepen our understanding of intraslab earthquakes generated by the reactivation of subducted outer‐rise bending faults. This study integrates high‐resolution seismic velocity models with numerical modeling results to investigate the roles of slab ...

Optical Spectra of Radio-Loud and Radio-Quiet Active Galactic Nuclei [PDF]
Symposium - International Astronomical Union, 1982 Many radio galaxies have strong emission lines in their optical spectra. The fraction with such lines is much larger than in “normal” galaxies. Radio galaxies generally also have very bright nuclei; thus those with strong emission lines are similar in both respects to Seyfert galaxies.

The Astrophysical JournalTo facilitate new studies of galaxy-merger-driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over 10,000 z < 0.15 galaxies observed by the Sloan Digital Sky Survey-IV ...

SMA Observations of the Archetypal Compact Steep-spectrum Radio Source 3C 303.1
The Astrophysical JournalActive galactic nucleus (AGN) feedback plays a crucial role in shaping galaxy evolution. Numerical simulations show that the kinetic energy transfer efficiency from radio jets to the interstellar medium (ISM) is relatively high, suggesting a significant ...
