We investigate the relation between the characteristics of the circumnuclear stellar population and both the galaxy morphology and the presence of close companions for a sample of 35 Seyfert 2 nuclei. Fifteen galaxies present unambiguous signatures of recent episodes of star formation within ≈300 pc from the Jansky Fellow Gemini Fellow

Formation and disruption of dark-matter cusps are reviewed. Accumulation of baryons at the center of a halo can displace the dark matter, converting singular density cusps into low-density cores. The displaced mass can be of order ∼ 10M• with M• the mass of the infalling population. If M• is identified with the masses of the black holes currently observed at the centers of bright galaxies, pred...

We have reconstructed possible orbits for a collection of stars located within 0.5 arcsec of Sgr A *. These orbits are constrained by observed stellar positions and angular proper motions. The construction of such orbits serves as a baseline from which to search for possible deviations due to the unseen mass distribution in the central 1000 AU of the Galaxy. We also discuss the likelihood that ...
