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}.
The radio/IR/gamma-ray correlation in galaxies is an emergent geometric property of line-of-sight integration through radially structured discs, not a signature of local cosmic-ray calorimetry.
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.
LRDs require Compton-thick gas at moderate metallicity plus high accretion rates producing weak X-rays to explain their non-detection, implying they are not chemically pristine.
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.
No kilonova detected from sub-solar GW candidate S251112cm, but coincident IIb supernova SN 2025adtq yields suggestive evidence for the superkilonova channel, though inconclusive after accounting for chance coincidence.
A tiered observational strategy is outlined to identify planetary-scale broadband radio technosignatures (BRaTs) from advanced civilizations up to 100 pc away using multi-parameter diagnostics to separate them from natural signals.
Radio AGN jets inject a total kinetic power density of 10^32 to 10^33 W per cubic megaparsec from z=0 to 2.5, matching requirements for feedback in galaxy evolution models.
N68 is a new cloud-cloud collision site in the G35 complex where two molecular clouds are colliding, triggering massive star formation alongside collect-and-collapse and radiation-driven implosion processes.
Time-dependent cosmic ray electron spectra in a simulated galactic disk match steady-state solutions up to 500 GeV but become steeper and more disk-confined at higher energies due to recent injections.
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.
Upper limits on the cosmic abundance of Kardashev Type III radio-broadcasting populations are set at less than one per 10^17 stars using radio source counts and commensal SETI field limits.
Multi-scale radio observations of 15 local U/LIRGs decompose emission to show nuclear components contribute ~50% on average while diffuse SF-related emission dominates ~80% of total power, with radio excess linked to AGN rather than boosted star formation.
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.
JWST finds infrared counterparts for nearly all micro-Jy radio sources, with star formation explaining the radio output in roughly 79% of cases after accounting for non-linear luminosity relations.
Simulations predict ngVLA at 100 GHz can detect galaxies above 10^9 solar masses at any redshift while SKA low frequencies reach massive dusty galaxies to z=5-7.
In X-ray selected AGN, those hosting ultra-fast outflows exhibit larger radio extensions and steep spectra matching wind-driven shock models.
