Neural-network surrogate accelerated MCMC infers multipolar magnetic field parameters for PSR J0740+6620 from NICER data, finding broad multimodal posteriors and disfavoring a zero-offset model.
X-ray timing and spectral analysis of ASKAP J174508.9-505149 detects matching periodicity and features consistent with an accreting magnetic CV.
Mass ratio reversals produce qualitatively different contributions to BBH merger rates and masses in COMPAS versus SEVN simulations, with core-growth dominating and most systems arising from massive low-metallicity progenitors.
Deep NIR adaptive-optics imaging rules out a helium-star companion to the eclipsing millisecond pulsar PSR J1928+1815, favoring a massive white dwarf.
Mass-ratio reversal in isolated binaries offers a viable formation path for GW241011-like events under specific stellar-evolution and interaction conditions.
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.
Multi-epoch observations of 1A 1246-588 show blackbody temperature rising from 0.28 to 0.39 keV with emitting radius 6.9-13.8 km and Comptonization photon index varying 1.8-2.3, consistent with atoll-state changes from accretion power redistribution.
A centered swept-back multipolar magnetic field up to octupole order reproduces the bolometric thermal X-ray light curve of MSP J0030+0451.
Adiabatic mass-loss models for massive helium stars give critical mass ratios 0.7-3.0 on the main sequence and 1.5-27 on the Hertzsprung gap, lowered by winds and adjusted by isotropic re-emission.
A census of ~3600 variable compact radio sources at 3 GHz from VLASS epochs 1 and 2, with 5-9% showing >30% flux changes above 20-300 mJy and most consistent with blazars or quasars.
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.
Observational evidence links obscured super-Eddington accretion to slower precessing jets in stellar-mass compact object systems, contrasting with fixed fast jets in low-density environments.
Tidal deformability modeling for pulsar companions enables constraints on their equations of state by matching predicted orbital precession to timing data from four systems.
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.
