The double-white-dwarf model for sources like CHIME/ILT J1634+44 predicts a beat-period drift of |P_b dot| ~ 10^{-10} s s^{-1}, producing tens of seconds of O-C timing drift in one year and enabling a minimal falsifiable test via joint period and derivative measurements.
IXPE data on magnetar 1E 1547.0-5408 show high linear polarization from a small hot spot whose phase-dependent angle is fit by a rotating vector model, with a marginal energy-dependent dip in polarization degree that may indicate vacuum resonance but does not constitute compelling evidence for biref
Targeted PTA searches for CWs from 114 AGN in NANOGrav 15 yr data yield no detections, factor-of-two tighter limits than all-sky searches, and updated constraints ruling out part of the parameter space for a binary in 3C 66B.
Crab pulsar interpulse X-ray counts match the Skellam distribution expected from two independent Poisson processes, while the main pulse shows excess variance that disappears upon averaging over rotations with no detected pulse-to-pulse memory.
Joint NICER+IXPE pulse-profile modeling of SRGA J144459.2-604207 favors large neutron-star mass and radius with two independent hotspots but shows strong sensitivity to joint-analysis methodology.
Binary pulsar timing can constrain quadratic scalar ULDM couplings between 2e-22 and 2e-21 eV and vector ULDM couplings between 1e-23 and 1e-18 eV via resonant orbital effects.
Observational case study of PSR J2338+4818 providing updated timing, single-pulse statistics from 27,228 detections, and scintillation parameters with no detected nulling.
Tidal deformability modeling for pulsar companions enables constraints on their equations of state by matching predicted orbital precession to timing data from four systems.
Discovery of an eclipsing neutron star LMXB with clocked bursts, orbital period 6.483 hr, companion mass 0.6-0.8 Msun, and helium burst indications from energy ratio 120-130.

A Falsifiable Timing Test for the Double-White-Dwarf Model of Long-Period Transients
