PSR J0740+6620 has an equatorial radius of 13.7^{+2.6}_{-1.5} km, and multi-messenger data constrain 1.4 and 2.08 solar-mass neutron star radii to 12.45 and 12.35 km respectively.
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.
PKS 0346-27 displayed a prolonged 2018 gamma-ray high state with ~1.5-hour variability, harder spectrum, and SED transition from LSP to ISP class, with one-zone leptonic modeling indicating lower magnetic field, larger radius, and higher electron energies than in quiescence.
