The 2dF-SDSS LRG and QSO (2SLAQ) Luminous Red Galaxy Survey
R. Cannon, M. Drinkwater, A. Edge +29
We present a spectroscopic survey of almost 15,000 candidate intermediate-redshift Luminous Red Galaxies (LRGs) brighter than i=19.8, observed with 2dF on the Anglo-Australian Tele…
Evolution in the clustering strength of radio galaxies
S. Fine, T. Shanks, N. Nikoloudakis +1
We cross match the NVSS and FIRST surveys with three large photometric catalogues of luminous red galaxies (LRGs) to define radio-loud samples. These have median redshifts 0.35, 0.…
The evolution of host mass and black hole mass in QSOs from the 2dF QSO Redshift Survey
S. Fine, S. M. Croom, L. Miller +9
We investigate the relation between the mass of super-massive black holes (Mbh) in QSOs and the mass of the dark matter halos hosting them (Mdh). We measure the widths of broad emi…
Measuring BAO and non-Gaussianity via QSO clustering
U. Sawangwit, T. Shanks, S. M. Croom +4
Our goals are (i) to search for BAO and large-scale structure in current QSO survey data and (ii) to use these and simulation/forecast results to assess the science case for a new,…
The Civ line width distribution for quasars and its implications for broad-line region dynamics and virial mass estimation
S. Fine, S. M. Croom, J. Bland-Hawthorn +4
We perform an extensive analysis of the Civ line in three large spectroscopic surveys of quasars. Differing approaches for fitting the Civ line can be found in the literature, and…
Narrow-line region gas kinematics of 24,264 optically-selected AGN: the radio connection
J. R. Mullaney, D. M. Alexander, S. Fine +3
Using a sample of 24264 optically selected AGNs from the SDSS DR7 database, we characterise how the profile of the [OIII] emission line relates to bolometric luminosity (L_Bol), Ed…
The Stripe 82 1-2 GHz Very Large Array Snapshot Survey: Multiwavelength Counterparts
Matthew Prescott, I. H. Whittam, M. J. Jarvis +6
We have combined spectrosopic and photometric data from the Sloan Digital Sky Survey (SDSS) with GHz radio observations, conducted as part of the Stripe 82 GHz Snapshot…
The 2QDES Pilot : The luminosity and redshift dependence of quasar clustering
Ben Chehade, T. Shanks, J. Findlay +10
We present a new redshift survey, the 2dF Quasar Dark Energy Survey pilot (2QDESp), which consists of quasars from deg of the southern sky, base…
Galaxy And Mass Assembly (GAMA): The 325 MHz Radio Luminosity Function of AGN and Star Forming Galaxies
Matthew Prescott, T. Mauch, M. J. Jarvis +16
Measurement of the evolution of both active galactic nuclei (AGN) and star-formation in galaxies underpins our understanding of galaxy evolution over cosmic time. Radio continuum o…
Counting quasar--radio source pairs to derive the millijansky radio luminosity function and clustering strength to z=3.5
S. Fine, T. Shanks, R. Johnston +2
We apply a cross-correlation technique to infer the mJy radio luminosity function (RLF) from the NRAO VLA sky survey (NVSS) to . We measure the over density of…
Composite reverberation mapping
S. Fine, T. Shanks, S. M. Croom +7
Reverberation mapping offers one of the best techniques for studying the inner regions of QSOs. It is based on cross-correlating continuum and emission-line light curves. New time-…
Stacked reverberation lags at high redshift
S. Fine, T. Shanks, P. Green +9
Over the past 20years reverberation mapping has proved one of the most successful techniques for studying the local (<1pc) environment of super-massive black holes that drive activ…
Constraining the quasar population with the broad-line width distribution
S. Fine, S. M. Croom, P. F. Hopkins +12
We measure the width of the MgII line in quasar spectra from the SDSS, 2QZ and 2SLAQ surveys and, by invoking an unnormalised virial mass estimator, relate the scatte…
Do all QSOs have the same black hole mass?
T. Shanks, S. M. Croom, S. Fine +2
QSOs from SDSS, 2QZ and 2SLAQ covering an order of magnitude in luminosity at fixed redshift exhibit similar amplitudes of clustering. In addition, QSO clustering evolution at z>0.…
