Galaxy Tomography with the Gravitational Wave Background from Supermassive Black Hole Binaries [Title version 1]

Y. Q. Chen, M. Daniel, D. D'Orazio, A. Mitridate et autres

The detection of a stochastic gravitational wave background by pulsar timing arrays suggests the presence of a supermassive black hole binary population. Although the observed spectrum generally aligns with predictions from orbital evolution driven by gravitational wave emission in circular orbits, there …

The NANOGrav 15 yr Dataset: Improved Timing Precision with Very Long Baseline Interferometry Astrometric Priors

S. Fiscella, M. Lam, G. Agazie, A. Anumarlapudi et autres

Accurate pulsar astrometric estimates play an essential role in almost all high-precision pulsar timing experiments. Traditional pulsar timing techniques refine these estimates by including them as free parameters when fitting a model to observed pulse time-of-arrival measurements. However, reliable sub-milliarcsecond astrometric estimations …
