Massive black hole masses in the context of gravitational wave observations
Abstract
The recent discovery of gravitational waves from merging pairs of massive black holes [1-4] and even neutron stars [5] has marked the beginning of a new chapter in astronomy. The increasing sensitivity of the next generation of ground-based gravitational wave detectors and of the future space-borne ones will allow for the detection of high redshift merging black hole events, down to the realm of the first-generation black holes which is inaccessible to present and future electromagnetic observations. To better estimate the expected rates of black hole mergers and mass ratios [6], existing all-sky catalogues of black hole masses (e.g. BH-Cat [7]) needs to be further developed and refined based on current observations.In the context of Romanian participation to LISA collaboration, we will present an updated version of the massive and supermassive black hole mass catalog, BH-Cat, together with its mass function and its implication for the LISA space mission. This catalog can be used to predict the mass and space distribution of the first-generation black holes, test the feedback between the black holes and the hosting galaxy evolution activities, study the growth mechanism of the black holes and predict the black holes mass merger ratios.1.
