Multi-wavelength pulse profile modeling of PSR J0437-4715 with radio prior yields mass 1.38±0.03 solar masses and radius 13.25 km at 68% confidence.
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.
A centered swept-back multipolar magnetic field up to octupole order reproduces the bolometric thermal X-ray light curve of MSP J0030+0451.
A Bayesian combination of eight M-R posteriors for PSR J0030+0451 yields M = 1.46^{+0.09}_{-0.08} M_⊙, R = 12.69^{+0.64}_{-0.55} km while marginalizing over unknown model systematics.
NE2025 refits the thick disk, thin disk, and spiral arms of the NE2001 model and adds refined clumps, delivering 20 times better median pulsar distance accuracy and 100 percent better scattering predictions than NE2001.
Hierarchical Bayesian analysis of ~50 binary pulsars finds moderate evidence for mass-spin anti-correlation (ρ = -0.26) in the recycled population, plus a small mass offset by white-dwarf companion type and confirmation of companion-mass–eccentricity correlation in DNS systems.
JRT will dedicate ~800 hours/year to VLBI and, when combined with SKA-Mid, is projected to improve network performance for pulsar distance measurements and event-horizon-scale imaging.
