THE HIDDEN “AGN MAIN SEQUENCE”: EVIDENCE FOR A UNIVERSAL BLACK HOLE ACCRETION TO STAR FORMATION RATE RATIO SINCE z ∼ 2 PRODUCING AN M BH-M * RELATION
Using X-ray stacking analyses we estimate the average amounts of supermassive black hole (SMBH) growth taking place in star-forming galaxies at z ~ 1 and z ~ 2 as a function of galaxy stellar mass (MExpand

The accretion of galaxies into groups and clusters
We use the galaxy stellar mass and halo merger tree information from the semi-analyticmodel galaxy catalogue of Font et al. (2008) to examine the accretion of galaxies into a large sample of groupsExpand

Discovery of Three z > 6.5 Quasars in the VISTA Kilo-Degree Infrared Galaxy (VIKING) Survey
Studying quasars at the highest redshifts can constrain models of galaxy and black hole formation, and it also probes the intergalactic medium in the early universe. Optical surveys have to dateExpand

The 2dF QSO Redshift Survey — V. The 10k catalogue
We present a catalogue comprising over 10 000 QSOs covering an effective area of 289.6 deg2, based on spectroscopic observations with the 2-degree Field (2dF) instrument at the Anglo-AustralianExpand

A new diagnostic of active galactic nuclei : revealing highly absorbed systems at redshift >0.3.
We introduce the Mass-Excitation (MEx) diagnostic to identify active galactic nuclei (AGNs) in galaxies at intermediate redshift. In the absence of near-infrared spectroscopy, necessary for usingExpand

The Frequency of Barred Spiral Galaxies in the Near-Infrared*
We have determined the fraction of barred galaxies in the H-band for a statistically well-defined sample of 186 spirals drawn from the Ohio State University Bright Spiral Galaxy Survey. We find 56%Expand

Testing the evolutionary link between submillimetre galaxies and quasars: CO observations of QSOs at z∼ 2
We have used the IRAM Plateau de Bure millimeter interferometer and the UKIRT 1– 5µm Imager Spectrometer (UIST) to test the connection between the major phases of spheroid growth and nuclearExpand

The dark nemesis of galaxy formation : why hot haloes trigger black hole growth and bring star formation to an end
Galaxies fall into two clearly distinct types: `blue-sequence' galaxies that are rapidly forming young stars, and `red-sequence' galaxies in which star formation has almost completely ceased. MostExpand

GEMINI IMAGING OF QSO HOST GALAXIES AT Z ∼ 2
We present results of a Gemini adaptive optics (AO) imaging program to investigate the host galaxies of typical QSOs at z ~ 2. Our aim is to study the host galaxies of typical L QSOs at the epoch ofExpand

Line emission in the brightest cluster galaxies of the NOAO Fundamental Plane and Sloan Digital Sky Surveys
We examine the optical emission-line properties of brightest cluster galaxies (BCGs) selected from two large, homogeneous data sets. The first is the X-ray selected National Optical AstronomyExpand
