XPSI: Xray Pulse Simulation and Inference
Abstract
XPSI simulates rotationallymodified (pulsed) surface Xray emission from neutron stars, taking into account relativistic effects on the emitted radiation. This can then be used to perform Bayesian statistical inference on real or simulated astronomical data sets. Model parameters of interest may include neutron star mass and radius (useful to constrain the properties of ultradense nuclear matter) or the system geometry and properties of the hot emitting surfaceregions. To achieve this, XPSI couples code for likelihood functionality (simulation) with existing opensource software for posterior sampling (inference).
