Black hole growth and host galaxy morphology (2010)

Schawinski, Kevin, Urry, C. Megan, Virani, Shanil, Coppi, Paolo, Bamford, Steven P., Treister, Ezequiel, ...

We use data from large surveys of the local Universe (SDSS+Galaxy Zoo) to show that the galaxy-black hole connection is linked to host morphology at a fundamental level. The fraction of early-type...

Galaxy Zoo: The fundamentally different co-evolution of supermassive black holes and their early- and late-type host galaxies (2010)

Schawinski, Kevin, Urry, C. Megan, Virani, Shanil, Coppi, Paolo, Bamford, Steven P., Treister, Ezequiel, ...

We use data from the Sloan Digital Sky Survey and visual classifications of morphology from the Galaxy Zoo project to study black hole growth in the nearby Universe (z < 0.05) and to break down the...

Angular correlation function of 1.5 million LRGs: clustering evolution and a search for BAO (2009)

Sawangwit, U., Shanks, T., Abdalla, F. B., Cannon, R. D., Croom, S. M., Edge, A. C., ...

We present the angular correlation function measured from photometric samples comprising 1562800 LRGs. Three LRG samples were extracted from the SDSS imaging data, based on colour-cut selections at z...

Cross-correlating WMAP5 with 1.5 million LRGs: a new test for the ISW effect (2009)

Sawangwit, U., Shanks, T., Cannon, R. D., Croom, S. M., Ross, Nicholas P., Wake, D. A.

We present the cross-correlation of the density map of LRGs and the temperature fluctuation in the CMB as measured by the WMAP5 observations. The LRG samples were extracted from imaging data of the...

The 2dF-SDSS LRG and QSO Survey: the QSO luminosity function at 0.4 (2009)

Croom, Scott M., Richards, Gordon T., Shanks, Tom, Boyle, Brian J., Strauss, Michael A., Myers, Adam D., ...

We present the QSO luminosity function of the completed 2dF-SDSS LRG and QSO (2SLAQ) survey, based on QSOs photometrically selected from Sloan Digital Sky Survey imaging data and then observed...

Clustering of Low-Redshift (z (2009)

Ross, Nicholas P., Shen, Yue, Strauss, Michael A., Berk, Daniel E. Vanden, Connolly, Andrew J., Richards, Gordon T., ...

We present measurements of the quasar two-point correlation function, \xi_{Q}, over the redshift range z=0.3-2.2 based upon data from the SDSS. Using a homogeneous sample of 30,239 quasars with...

Photometric Selection of Emission Line Galaxies, Clustering Analysis and a Search for the ISW effect (2009)

Bielby, Rich, Shanks, T., Sawangwit, U., Croom, S. M., Ross, Nicholas P., Wake, D. A.

We investigate the use of simple colour cuts applied to the SDSS optical imaging to perform photometric selections of emission line galaxies out to z

The Two-Point Correlation of 2QZ Quasars and 2SLAQ LRGs: From a Quasar Fueling Perspective (2009)

Norman, Dara J., DePropris, Roberto, Ross, Nicholas P.

Public data from the 2dF quasar survey (2QZ) and 2dF/SDSS LRG & QSO (2SLAQ), with their vast reservoirs of spectroscopically located and identified sources, afford us the chance to more accurately...

Quasar Clustering from SDSS DR5: Dependences on Physical Properties (2008)

Shen, Yue, Strauss, Michael A., Ross, Nicholas P., Hall, Patrick B., Lin, Yen-Ting, Richards, Gordon T., ...

Using a homogenous sample of 38,208 quasars with a sky coverage of $4000 {\rm deg^2}$ drawn from the SDSS Data Release Five quasar catalog, we study the dependence of quasar clustering on luminosity,...

The 2dF-SDSS LRG and QSO survey: evolution of the clustering of luminous red galaxies since z = 0.6 (2008)

Wake, David A., Sheth, Ravi K., Nichol, Robert C., Baugh, Carlton M., Bland-Hawthorn, Joss, Cannon, Russell, ...

We present an analysis of the small-to-intermediate scale clustering of samples of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey and the 2dF-SDSS LRG and QSO (2SLAQ) survey carefully...

The 2dF-SDSS LRG and QSO survey : QSO clustering and the L-z degeneracy (2008)

Da Angela, Jose A., Shanks, Tom, Croom, Scott M., Weilbacher, Peter M., Brunner, Robert J., Couch, Warrick J., ...

We combine the quasi-stellar object (QSO) samples from the 2dF QSO Redshift Survey (2QZ) and the 2dF-Sloan Digital Sky Survey luminous red galaxy (LRG) and QSO Survey (2dF-SDSS LRG and QSO, hereafter...
