Customized chromatic noise models applied to NANOGrav 15 yr data raise the Bayes factor for Hellings-Downs GWB correlations by a factor of ~8, lower the amplitude to 2.1e-15, and increase the spectral index to 3.5.
Scintillation study of PSR B1257+12 finds distant scattering screens at 166-354 pc and a relatively clean immediate pulsar environment.
Detection and measurement of an extreme scattering event toward PSR J2313+4253 yielding a scattering region at 1.04 kpc distance, 15 AU transverse size, and ~220 day duration.
SKA-Low can characterise mid-latitude ionospheric structure via multiple interferometric phase-screen and scintillation methods, with forward modelling linking observables to physical plasma conditions.
FAST observations of three pulsars detect scintillation arcs whose curvatures scale as ν^{-2} with frequency, locating scattering screens at 30-420 pc.
Follow-up observations of PSR J2338+4818 detect 27,228 single pulses with no nulling and measure scintillation timescales of 2.93-25.26 min and bandwidths of 1.68-27.41 MHz.
