No significant evolution of relations between Black hole mass and Galaxy total stellar mass up to z~2.5
Hyewon Suh, Francesca Civano, Benny Trakhtenbrot +4
We investigate the cosmic evolution of the ratio between black hole mass (MBH) and host galaxy total stellar mass (Mstellar) out to z~2.5 for a sample of 100 X-ray-selected moderat…
The CO(3-2)/CO(1-0) luminosity line ratio in nearby star-forming galaxies and AGN from xCOLD GASS, BASS and SLUGS
Isabella Lamperti, Amélie Saintonge, Michael Koss +11
We study the r31=L'CO(3-2)/L'CO(1-0) luminosity line ratio in a sample of nearby (z < 0.05) galaxies: 25 star-forming galaxies (SFGs) from the xCOLD GASS survey, 36 hard X-ray sele…
The mass relations between supermassive black holes and their host galaxies at 1<z<2 with HST-WFC3
Xuheng Ding, John Silverman, Tommaso Treu +10
Correlations between the mass of a supermassive black hole and the properties of its host galaxy (e.g., total stellar mass (M*), luminosity (Lhost)) suggest an evolutionary connect…
Where do quasar hosts lie with respect to the size-mass relation of galaxies?
John D. Silverman, Tommaso Treu, Xuheng Ding +8
The evolution of the galaxy size - stellar mass (Mstellar) relation has been a puzzle for over a decade. High redshift galaxies are significantly more compact than galaxies observe…
How to Fuel an AGN: Mapping Circumnuclear Gas in NGC 6240 with ALMA
Anne M. Medling, George C. Privon, Loreto Barcos-Muñoz +15
Dynamical black hole mass measurements in some gas-rich galaxy mergers indicate that they are overmassive relative to their host galaxy properties. Overmassive black holes in these…
Hawaii Two-0: High-redshift galaxy clustering and bias
Róbert Beck, Conor McPartland, Andrew Repp +2
We perform an analysis of two-point galaxy clustering and galaxy bias using Subaru Hyper-Suprime Cam (HSC) data taken jointly by the Subaru Strategic Program and the University of…
