NuSTAR Observation of the TeV-detected Radio Galaxy 3C 264: Core Emission and the Hot Accretion Flow Contribution

The Astrophysical Journal
3C 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).

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides

Advanced Science, Volume 13, Issue 18, 27 March 2026.
This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...

PAGaN I: Multi-Frequency Polarimetry of AGN Jets with KVN

, 2015
Active Galactic Nuclei (AGN) with bright radio jets offer the opportunity to study the structure of and physical conditions in relativistic outflows. For such studies, multi-frequency polarimetric very long baseline interferometric (VLBI) observations ...

Leaky‐Integrate‐Fire Neuron via Synthetic Antiferromagnetic Coupling and Spin‐Orbit Torque

Advanced Science, Volume 13, Issue 16, 18 March 2026.
A spintronic leaky‐integrate‐and‐fire neuron is realized using Spin Orbit Torque driven domain‐wall motion for integration and synthetic antiferromagnetic coupling for the leaky process. The specialized Hall‐bar geometry enables controlled DW dynamics, achieving repeatable integration and firing events. This compact, CMOS‐compatible design highlights a

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

Advanced Science, Volume 13, Issue 14, 9 March 2026.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...

An Excess of Active Galactic Nuclei Triggered by Galaxy Mergers in MaNGA Galaxies of Stellar Mass ∼1011 M ⊙

The Astrophysical Journal
To 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 ...

How relevant is the torus activity/geometry for the TeV gamma-rays emitted in the jet of M87 ? [PDF]

, 2003
Motivated by unification schemes of active galactic nuclei, we review evidence for the existence of a small-scale dust torus in M87, a Fanaroff-Riley Class I radio galaxy.

Unified Analysis of Fermionic Tunneling, Barrow‐Exponential Entropy Corrections, and Plasma Lensing in Carrollian Reissner‐Nordström Spacetime

Annalen der Physik, Volume 538, Issue 3, March 2026.
Carrollian Reissner‐Nordström black holes are investigated through fermionic tunneling, entropy‐corrected thermodynamics, and plasma‐modified gravitational lensing. The generalized uncertainty principle introduces minimal‐length corrections to the Hawking temperature, while the combined Barrow‐Exponential entropy reveals smooth thermodynamic crossovers

Panic at the ISCO: Time-varying Double-peaked Broad Lines from Evolving Accretion Disks Are Common among Optically Variable AGNs

The Astrophysical Journal
About 3%–10% of Type I active galactic nuclei (AGNs) have double-peaked broad Balmer lines in their optical spectra originating from the motion of gas in their accretion disk.
