Spectroscopic and imaging confirmation of the brightest known quadruply-lensed quasar J1330-0905 at z=2.22 with Einstein radius ~0.45 arcsec and predicted magnification ~56.
First polarization measurements of MAXI J1744-294 reveal a common Faraday screen with RM = -63606 rad m^{-2} matching the Galactic center magnetar, confirming the transient's location in the nuclear star cluster and suggesting an intrinsic RM for Sgr A*.
SPICE-RACS DR2 delivers the largest single Faraday rotation measure catalog from a radio survey, with 250,000-340,000 RMs across most of the sky at median uncertainty of 2 rad m^{-2}.
Quasar nebulae at z~1 are diverse objects shaped by galaxy interactions, host gas, group environments, and quasar activity, with the largest irregular ones most tied to interactions.
New ASKAP continuum imaging classifies jet morphologies in 173 G4Jy-3CRE sources (66% of sample) including 37 newly detected jets and identifies six new optical counterparts.
VLBA multi-frequency imaging resolves a collimated jet extending ~745 pc in the z=3.4351 super-Eddington radio-loud quasar ID830, with v ≳ 0.19c and viewing angle ≲ 79° but δ ~ 1.
Post-starburst galaxies at cosmic noon show very low radio detection rates and compact weak sources, consistent with short-lived low-luminosity AGN, while older quiescent galaxies exhibit stronger extended radio emission.
EP J174942.2-384834 is classified as a very faint X-ray transient black hole candidate based on its hard X-ray spectra, optical/UV brightening correlated with X-rays, and lack of radio emission.
Five new HI 21-cm absorption detections in LERGs and HERGs at z<0.5 reveal disturbed gas kinematics with velocity offsets over 350 km/s and a 3% detection rate consistent with lower-redshift samples.
The Argus Array and DSA are projected to detect 47 and 82 long GRB afterglows per year respectively from Fermi triggers, along with over 100 independent detections annually and some short GRB counterparts.
Six new Galactic radio transients found and classified into two types, proposed to originate from wide-orbit white dwarf binaries.
A z=1.715 radio-loud quasar exhibits a ~10,000 K blackbody UV continuum and three-component blackbody photometry, marking it as a candidate transitional Little Red Dot.
Bayesian tension analysis shows Planck CMB dipole in >5σ disagreement with CatWISE infrared sources and moderate-to-strong disagreement with radio surveys NVSS and RACS, with evidence for shared astrophysical signals in some catalogs.
A census of ~3600 variable compact radio sources at 3 GHz from VLASS epochs 1 and 2, with 5-9% showing >30% flux changes above 20-300 mJy and most consistent with blazars or quasars.
The P3 selector achieves 0.9809 purity and 0.8869 completeness for QSO candidates in selected fields, outperforming Gaia's official probabilities.
Reports results from two searches for new radio lenses in existing surveys and discusses the completeness of the population usable for constraining dark matter properties via astrometric perturbations.
Late-time radio rebrightening in SN 2012ap is consistent with either progenitor mass-loss variation producing a density enhancement or an off-axis energetic jet viewed at large angle, potentially reclassifying it as GRB-like rather than weakly engine-driven.
AGN emission from central galaxies hides galaxy clusters in SZ surveys; CARMA-based subtraction recovers high-SNR detections in ACT maps for three specific clusters.
Dwarf galaxies host compact thermal HII regions powered by up to 100,000 O-type stars and exhibit radio variability consistent with AGNs.
In X-ray selected AGN, those hosting ultra-fast outflows exhibit larger radio extensions and steep spectra matching wind-driven shock models.
Deep VLBI observations of four ULXs yield no compact radio detections and tight upper limits, disfavoring persistently bright hard-state-like compact cores.
High-precision VLBI detects 250 μas core shift between 8.4 and 43.2 GHz in BL Lacertae, with fitted index k_r = 1.18 consistent with equipartition.
No credible isolated black hole candidates were found in a Gaia DR3 search within 15 pc of the Sun after multi-wavelength checks dismissed five sources as probable artifacts.
