Discovery of Thunder, a bow-shock PWN powered by PSR J1631-4722 in SNR G336.7+0.5 (Nimbus), characterized with radio, X-ray, and polarization data at assumed 7 kpc distance with age ~30-45 kyr.
A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
A polarization catalog of 6,131 bursts from FRB 20240114A reveals linearly decreasing rotation measure, stable dispersion measure, high linear polarization fractions, low circular polarization, and a broad distribution of intrinsic polarization angles, indicating a dynamically evolving magneto-ionic
Four new FRBs discovered commensally during Parkes PTA pulsar observations, including one with record S/N and unusual spectrum; all highly polarized.
PSR J2101-4802 is a transitional millisecond pulsar with a ~1-day orbit, 0.15 solar mass He-WD companion, and large orbital period derivative that links redback-like systems to detached binaries.
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.
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.
Coherent timing solutions at 150 MHz for 17 pulsars from Irish LOFAR observations, including 7 without prior solutions.
No measurable changes in radio and X-ray emission were observed around four glitches in PSR J2229+6114, providing evidence that magnetar-like post-glitch activity is more common in high-B rotation-powered pulsars.
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.
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.
