Synthetic high-mass X-ray binary populations in a cosmological frame
Abstract
High-mass X-ray binaries are systems constituted by a massive star and a compact object. The study of these systems is important to understand the origin and evolution of compact objects. Considering recent results from other authors, which propose a dependence of the number of these binary systems on their chemical abundances, we present a model for the populations of high-mass X-ray binaries in nearby galaxies grafted onto hydrodynamical cosmological simulations. The simulations include star formation and chemical evolution, which allow us to obtain a self-consistent description of the high-mass X-ray binary populations in galaxies. We investigate the properties of high-mass X-ray binary populations in our models, and compare them with those observed in nearby galaxies.
