The mass of supermassive black holes (BHs) correlates with the bulge mass orstellar velocity dispersion of their host galaxies. The co-evolution of BHs andgalaxies could explain these correlations but this picture was challenged by aseries of arguments. We propose to explore three local red nugget analogs thathave high velocity dispersion relative to their bulge mass. Based on theXMM-Newton observations we will build gravitating mass profiles and compute thedark matter halo mass of the galaxies. By utilizing X-ray and optical data andresults of numerical simulations we will probe (1) the tightness of thecorrelation between BHs and dark matter halos (2) explore whether BHs and theirhost galaxies grow in sync and (3) estimate the frequency of red nuggets in the local universe.
