Binary population synthesis
Webobject binary merger, GW190425, with a total mass of-3.4+ 0.1 0.3 Me. This system lies five standard deviations away from the known Galactic population of binary neutron stars (BNSs) with a mean total mass of-2.66+ M 0.12 0.12 . The comparable merger rate of this system to GW170817 raises several issues that we attempted to elucidate in this work.

Even so, BPS models typically require a large number of simulation realizations, a computationally expensive endeavor, to generate statistically robust results. ...
WebIn this paper we present a brief overview of population synthesis methods with a discussion of their main advantages and disadvantages. In the second part, we present some recent results from synthesis models of close binary compact objects with emphasis on the predicted rates, their uncertainties, and the model input parameters the rates are … WebNov 15, 2024 · Binary population synthesis is the method by which predictions of varied observables of stellar populations can be made from theoretical models of binary stellar evolution. Binary stars have many more possible evolutionary outcomes compared to single stars and the relative rates of the different pathways, such as the rates of different ...
WebThis observed Z dependence for HMXB-dominated galaxies is consistent with both the local L X-SFR-Z relation and a subset of population synthesis models. Although the statistical significance of the observed trends is weak owing to the low X-ray statistics, these results constitute the first direct evidence connecting the redshift evolution of L ...

WebBinary population synthesis studies have been used extensively over the last two decades to interpret observations of compact-object binaries and to decipher the physical processes that lead to their formation.
WebBinary population synthesis generates population models of isolated stellar binaries under a set of parametrized assumptions. These models permit comparisons against observational data sets, such as X-ray binaries of gravitational-wave mergers.
