Spherically symmetric accretion from a nuclear young starburst onto a super massive black hole

The results of this thesis leads to an intrinsic link between the luminosity of a SMBH located at the center of a young nuclear starburst and the starburst parameters. However, the model here developed still does not include some potentially important physical ingredients and thus requires further improvement. So far we have assumed that stars are equally distributed within the star-forming region. Therefore, a more realistic model for the stellar density distribution has to be developed, as it was suggested by some authors (see, Rodriguez-González et al. 2007) who have considered relatively low mass stellar clusters and presented the results without accounting for the impact of gravity provided by the stellar component and the presence of the central black hole.
