Faraday conversion in magnetar winds explains the range of observed FRB circular polarization and yields constraints on near-source wind parameters from Stokes data.
toa_sp applies multiple single-pulse timing strategies to 688 pulses from RRAT J1913+1330, yielding 1.33 ms weighted RMS residuals (24% better than PSRCHIVE) while keeping all pulses.
Repeating FRBs show Gaussian-distributed intrinsic PAs with no periodicity, explained by stochastic magnetospheric axis wandering in an extended rotating vector model.
FAST observations confirm periodic nulling in PSR B0751+32 at 35 percent fraction with evolving periodicity, stable-then-declining pulse components, and no subpulse drifting, challenging geometric models.
New EP-FXT data on the 2024 outburst of magnetar 1E 1841-045 shows energy-dependent multi-peaked pulses, spectral hardening, BB temperature-pulse intensity correlations, and effective separation from supernova remnant emission.
Close major galaxy pairs exhibit 8.8% lower HI gas fractions and 15% higher HI star formation efficiency in S+S systems than mass- and redshift-matched isolated controls.
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.
A 9-hour FAST observation covering ~4230 GCs in M49 found no FRBs and sets an upper limit of 4.7e-4 FRB GC^-1 hr^-1 above ~16.5 mJy ms fluence.
High-resolution FAST data reveal spike subpulses (strongly polarized, marginally resolved) in 21 pulsars and quasi-periodic subpulses (periods ~0.1-1 ms) in 13 pulsars, with checks for rotation period correlation.
FAST observations of three pulsars detect scintillation arcs whose curvatures scale as ν^{-2} with frequency, locating scattering screens at 30-420 pc.
Pilot FAST HD² survey reports 339 new HI detections in 10 deg² with 0.45 mJy rms, high DESI optical matching rates, and gas fraction relations consistent with ALFALFA, DINGO, and xGASS.
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.
