Optimal all-angle reconstruction of the Hellings-Downs curve
Jing-Hong Han, Zhi-Chao Zhao
Pulsar timing arrays (PTAs) detect nanohertz gravitational waves through spatial correlations between the timing residuals of different pulsars. For an isotropic, unpolarized stoch…

Solving Hamiltonian Constraint Equation with Physics-Informed Neural Networks
Yu-Chen Zhou, Hao Ma, Zhoujian Cao +6
Numerical relativity (NR), solving Einstein equation numerically, plays an important role in source modelling for gravitational wave astronomy. Traditional methods for NR including…

Forecasting graviton-mass constraints from the full covariance of PTA-astrometry ORF estimators
Jing-Hong Han, Zhi-Chao Zhao
We develop a full-covariance formalism for pulsar timing array(PTA) -- astrometry verlap reduction function (ORF) estimators and use it to forecast graviton-mass constraints from a…
