MeerKAT observations detect radio halos in 27% of 30 massive clusters at z>1, a rate lower than at intermediate redshifts but above model predictions, with power-mass scaling similar to lower-z samples.
Radio observations of Faraday rotation in CARLA J1510+5958 at z=1.72 yield a lower limit of 0.4 μG on the average magnetic field strength in the proto-intra-cluster medium.
No extraterrestrial technosignatures detected in an all-sky ultra-narrowband imaging survey at 50-86 MHz with OVRO-LWA, achieving ~100 Jy sensitivity and EIRP limits of 10^14 W at 10 pc.
A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
Multi-frequency radio data supports Abell 980 as hosting a detached double-double radio galaxy formed by two jet episodes from the BCG with subsequent lateral drift causing loss of lobe colinearity.
First-year SWAYS observations report a superflare on EK Draconis with no low-frequency radio signal, interpreted as evidence that dense coronae in active stars inhibit type II/III burst instabilities.
Describes a distributed, memory-aware implementation of the widefield measurement operator for radio interferometry that decomposes into w-bin operators and optionally uses holographic matrices.
Rotationally modulated radio pulses with near-100% circular polarization from M dwarf ASKAP J181335-604720 are interpreted as coherent electron cyclotron maser emission from its magnetosphere based on simultaneous radio-optical observations.
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.
Fornax cluster magnetic field follows a power-law spectrum of slope ~2.7 with central strength ~5 μG scaling as n^1.6, consistent with recent central re-amplification and trends across 17 clusters.
A faint radio counterpart to SN 2025ulz was detected at 6-10 GHz, consistent with either supernova ejecta interacting with circumstellar material or an off-axis jet, supporting possible superkilonova scenarios.
VLA observations of six cataclysmic variables reveal polarized radio emission consistent with coherent mechanisms like electron-cyclotron maser emission or plasma radiation.
Multi-wavelength data classify the Einstein Probe transient EP250916a as a faint hard-state black hole X-ray binary candidate.
SN2025ulz is a type IIb supernova whose shock-cooling tail mimicked a kilonova, demonstrating a key contaminant for gravitational-wave counterpart searches.
Empirical scalability model for LOFAR DI pipeline runtime based on tests varying CPUs, data size, and sky model size, with validation on production runs.
This paper discusses observational, calibration, and imaging requirements for solar and heliospheric science with the SKA radio telescope.
