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 ...

A new delivery route to Galactic Nuclei: Warm halo cloud impacts
, 2010 We propose a new mechanism for the delivery of gas to the heart of galactic nuclei. We show that warm halo clouds must periodically impact galactic centers and potentially deliver a large (~10^{4-6} M_{solar}) mass of gas to the galactic nucleus in a ...

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
Advanced Materials, Volume 38, Issue 16, 17 March 2026.This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Limits from rapid TeV variability of Mrk 421
, 1997 The extreme variability event in the TeV emission of Mrk 421, recently reported by the Whipple team, imposes the tightest limits on the typical size of the TeV emitting regions in Active Galactic Nuclei (AGN).

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

Systematic Analysis of Changing-Look Active Galactic Nucleus Variability Using ZTF Light Curves
The Astrophysical JournalChanging-look active galactic nuclei (CLAGNs) are a unique population of AGNs that exhibit the appearance (turn-on) or disappearance (turn-off) of broad emission lines.

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 ...

XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy
The Astrophysical JournalGreen Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local Universe. They are believed to be analogs of high-redshift galaxies that reionized the Universe, and, indeed, the James Webb Space ...
