Evidence for non-merger co-evolution of galaxies and their supermassive black holes
R. J. Smethurst, R. S. Beckmann, B. D. Simmons +7
Recent observational and theoretical studies have suggested that supermassive black holes (SMBHs) grow mostly through non-merger (`secular') processes. Since galaxy mergers lead to…
Supermassive black holes in merger-free galaxies have higher spins which are preferentially aligned with their host galaxy
R. S. Beckmann, R. J. Smethurst, B. D. Simmons +7
Here we use the Horizon-AGN simulation to test whether the spins of SMBHs in merger-free galaxies are higher. We select samples using an observationally motivated bulge-to-total ma…
Gems of the Galaxy Zoos -- a Wide-Ranging Hubble Space Telescope Gap-Filler Program
William C. Keel, Jean Tate, O. Ivy Wong +13
We describe the Gems of the Galaxy Zoos (Zoo Gems) project, a gap-filler project using short windows in the Hubble Space Telescope's schedule. As with previous snapshot programs, t…
