25. AGN feedback in Massive Elliptical Galaxies (H)

Highlight

Massive elliptical galaxies universally host in their centers black holes with masses roughly proportional to the stellar masses of the hosts. Periodically, gas will accumulate at the centers of these systems due either (at early times) due to cosmological infall or (at later times) to secondary gas consequent to normal stellar evolution. This material will fuel central star-formation episodes...

28. The importance of obscured AGN-driven outflows in rapidly evolving galaxies in the local Universe

We have carried out an optical spectroscopic study of a sample of nearby ULIRGs with Seyfert nuclei, with the aim of investigating the nature of the nuclear warm gas outflows. We will complement this study with HST ACS/WFC and STIS observations to make high resolution [OIII]5007 emission line imaging and long-slit spectroscopy observations of the circumnuclear outflows in a sample of ULIRGs...

29. Do AGN environments support the model of AGN unification?

We have used the Sloan Digital Sky Survey (DR7) and Galaxy Zoo data to examine close neighbours to low-redshift Type-1 and Type-2 AGN. Our results show a strong color-distance relation for Type-2 AGN neighbours (but none for Type-1 AGN). We also see a trend in the ratio #Type-1/#Type-2 AGN neighbours to Type-2 AGN as a function of projected distance. Further, while 22% of the Type-1 AGN...

26. Nuclear coups in unequal mass galaxy mergers

We present the latest results from a suite of high-resolution hydrodynamical simulations of mergers between two disk galaxies, in which we vary the mass ratio and the directions of the two galactic angular momentum vectors. We study both the evolution of the central black holes and the fate of the galaxies themselves. One newly found aspect of galactic interaction is the occurrence, in some...
