Massive Black Hole Binary Systems in Hierarchical Scenario of Structure Formation

Esse é um artigo que deixei recentemente no Arxiv.
Nesse trabalho eu apresento uma forma de calcular a densidade numérica de sistemas binários de buracos negros supermassivos usando uma extensão do formalismo tipo Press-Schecher. Para ver o artigo completo clique aqui.

Abaixo segue o resumo em inglês do artigo:

Recently, it has increased the observational evidence that, in most galaxies there are massive black holes (MBH). On the other hand, the hierarchical scenario of structure formation describe which objects like galaxies and galaxy clusters are formatted by mergers of small objects. In this context, we can suppose that mergers of galaxies leads to the formation of MBH binary systems. It is expected that the merger of two MBH produces a gravitational waves signal detectable by the Laser Interferometer Space Antenna (LISA). In this work, we use the Press-Schechter formalism and its extention to take into account the analytical form for the merger rate of haloes that contains massive black holes. Also, we describe a way to determine the number of binary systems of MBH. 

Até a próxima.
