SDSSJ110546.07+145202.4 is the first known long-duration radio changing-look NLS1 galaxy whose outburst is explained by an accretion-rate change that triggered a powerful radio jet.
J1105+1452 transitioned to a megahertz peaked-spectrum source with a new compact jet of radius ~0.68 pc, apparent velocity ~0.64c, and Doppler factor ~12, while X-ray emission stayed disk-corona dominated.
An all-sky NEOWISE-based search using difference imaging and a CNN classifier trained on Cas A echoes detects no other historical Galactic supernova dust echoes at WISE sensitivity and delivers a catalog of 20477 Cas A echo positions.
A changing-look AGN exhibits a rapid accretion-driven spectral transition with broad-line region temperatures of approximately 11,800 K measured via Boltzmann plots and stable black hole mass estimates of 5 times 10 to the 7 solar masses across epochs.
Discovery and multi-wavelength follow-up of a new FU Orionis accretion outburst in V7995 Sgr with photometry and spectroscopy confirming the classification.
Multi-epoch X-ray analysis of PHL 1811 indicates its apparent weakness results from heavy obscuration by a radiatively driven wind rather than intrinsic X-ray weakness.
Optical-MIR lags of 39.1 days and 79.4 days are measured in Mrk 42 and Mrk 493, yielding dust reverberation radii of 0.032 pc and 0.065 pc with R_dust/R_BLR ratios of approximately 6-7.
An obscured tidal disruption event in SDSS J010320.39+140152.5 was identified through its mid- and near-infrared dust echo peaking at 5.4e43 Lsun.
HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.
New catalog identifies 30,345 mid-IR variable sources at ecliptic poles from NEOWISE data, with AGN dominating in the north and stars in the south plus three transients linked to obscured QSOs.
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.
NEOWISE-R data identifies ten new non-variable dust makers among WC stars (including three early subtypes), six new episodic dust makers, and revises the dust formation period of HD 36402 to 5.1 years.
Photometric reanalysis identifies UPK 13-c2 as a candidate late-K/early-M binary with circumbinary disk in the ~316 Myr cluster UPK 13, potentially the oldest main-sequence disk-eclipsing binary known.
Long-term multi-band photometry of SN 2019vxm shows initial thick CSM interaction, photosphere decoupling at 80-100 days, long-lasting dust emission, and a possible outer CSM rebrightening, implying a massive progenitor with extreme pre-explosion mass loss.
WISE data yield upper limits showing that no more than about 0.016% of nearby galaxies can host KIII-scale systems reprocessing at least 21% of a Milky Way-like stellar luminosity into 300 K waste heat.
Compiles WISE W1/W2 photometry and derives stellar masses for galaxies 1-10 Mpc with M_W1 < -13, showing most mass in few giants despite many dwarfs.
