Two FRBs exhibit microlensing signatures consistent with intermediate-mass black holes of masses approximately 500-600 and 1500-2500 solar masses, interpreted as possible evidence for isolated primordial black holes comprising about 4% of dark matter.
FRB dispersion measures reveal a large-scale excess of ionized gas in the northern sky spatially aligned with the Ursa Major supercluster.
Repeating FRBs show Gaussian-distributed intrinsic PAs with no periodicity, explained by stochastic magnetospheric axis wandering in an extended rotating vector model.
A search of repeating FRBs identifies RM flare candidates in FRB 20121102A, FRB 20201124A, and FRB 20180916B, suggesting such events may be common and tied to dynamic magneto-ionic environments.
CASM-256 is a new 256-antenna radio array at Owens Valley that uses real-time digital beamforming to search for fast radio bursts and galactic transients over a huge sky area.
Reports timing solutions and basic properties for 49 pulsars (18 new) from the AO327 survey, with emission feature notes and model comparisons for distances.
FRB 20240114A shows two epochs with distinct energy distribution indices and waiting time statistics, suggesting different burst types before and after March 21 2024.
Simulations indicate HI absorption in FRB spectra is detectable when scintillation decorrelation bandwidth differs markedly from absorption width, with ≳1000 stacked bursts needed at current sensitivities.
Population-level statistical test on repeating FRB DM evolution finds decreasing trends more common than increasing (p=0.033), consistent with young SNR expansion reducing local electron density.
Wideband observations show M28A giant pulses differ from FRB 20200120E bursts in duration, luminosity, timing statistics, and spectral structure, yielding no strong evidence for a direct link.
Simba simulations find that IGM gas fractions in cosmic web structures vary by only a few percent across feedback variants, while jet feedback noticeably enhances diffuse gas on the outskirts of filaments and knots.
The PINK updates enhance the CELEBI FRB pipeline with better astrometry, time-frequency gating, polarization calibration, DM optimization tools, and a software container for improved efficiency and localization of events like FRB 20251019A.
A reported periodic fast radio burst is reclassified as Galactic pulsar emission due to CHIME calibration and beam-pointing error.
