Isolated pulsar population synthesis with simulation-based inference

arXiv:2312.14848v2 Announce Type: replace-cross
Abstract: We combine pulsar population synthesis with simulation-based inference (SBI) to constrain the magneto-rotational properties of isolated Galactic radio pulsars. We first develop a framework to model neutron-star birth properties and their dynamical and magneto-rotational evolution. We specifically sample initial magnetic-field strengths, $B$, and spin periods, $P$, from log-normal distributions and capture the late-time magnetic-field decay with a power law. Each log-normal is described by a mean, $\mu_{\log B}, \mu_{\log P}$, and standard deviation, $\sigma_{\log B}, …
