Optical properties and spatial distribution of MgII absorbers from SDSS image stacking (2006)
Zibetti, Stefano, Menard, Brice, Nestor, Daniel B., Quider, Anna M., Rao, Sandhya M., Turnshek, David A.
We present a statistical analysis of the photometric properties and spatial distribution of more than 2,800 MgII absorbers with 0.37
QSO Absorption Lines from QSOs (2006)
Bowen, David V., Hennawi, Joseph F., Menard, Brice, Chelouche, Doron, Inada, Naohisa, Oguri, Masamune, ...
We present the results of a search for metal absorption lines in the spectra of background QSOs whose sightlines pass close to foreground QSOs. We detect MgII(2796,2803) absorption in Sloan Digital...
The Small-Scale Environment of Quasars (2006)
Serber, Will, Bahcall, Neta, Menard, Brice, Richards, Gordon
Where do quasars reside? Are quasars located in environments similar to those of typical L* galaxies, and, if not, how do they differ? An answer to this question will help shed light on the...
Average Extinction Curves and Relative Abundances for QSO Absorption Line Systems at 1 (2006)
York, Donald G., Khare, Pushpa, Berk, Daniel Vanden, Kulkarni, Varsha P., Crotts, Arlin P. S., Lauroesch, James T., ...
We have studied a sample of 809 Mg II absorption systems with 1.0 < z_abs < 1.86 in the spectra of SDSS QSOs, with the aim of understanding the nature and abundance of the dust and the chemical...
Constraining the photometric properties of MgII absorbing galaxies with the SDSS (2005)
Zibetti, Stefano, Menard, Brice, Nestor, Daniel, Turnshek, David
Using a sample of nearly 700 quasars with strong (W_0(2796)>0.8 Angstrom) MgII absorption lines detected in the Early Data Release of the SDSS, we demonstrate the feasibility of measuring the...
Detection of Cosmic Magnification with the Sloan Digital Sky Survey (2005)
Scranton, Ryan, Menard, Brice, Richards, Gordon T., Nichol, Robert C., Myers, Adam D., Jain, Bhuvnesh, ...
We present an 8 sigma detection of cosmic magnification measured by the variation of quasar density due to gravitational lensing by foreground large scale structure. To make this measurement we used...
The third data release of the Sloan Digital Sky Survey (2005)
Abazajian, Kevork N., Adelman-McCarthy, Jennifer K., Agueros, Marcel A., Allam, Sahar S., Anderson, Kurt S. J., Anderson, Scott F., ...
This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through 2003 June, includes imaging data in five bands over 5282 deg²,...

Kauffmann, Guinevere, White, Simon D. M., Heckman, Timothy M., Menard, Brice, Brinchmann, Jarle, Charlot, Stephane, ...
We use a complete sample of galaxies drawn from the SDSS to study how structure, star formation and nuclear activity depend on local density and on stellar mass. Local density is estimated by...
I present the current status of the cosmic magnification produced by systematic amplification of background sources by large-scale structures. After introducing its principle, I focus on its...
Improving the Accuracy of Cosmic Magnification Statistics (2002)
Menard, Brice, Hamana, Takashi, Bartelmann, Matthias, Yoshida, Naoki
The systematic magnification of background sources by the weak gravitational-lensing effects of foreground matter, also called cosmic magnification, is becoming an efficient tool both for measuring...
Weak lensing study of Abell 2029 (2002)
Menard, Brice, Erben, Thomas, Mellier, Yannick
Abell 2029 is one of the most studied clusters due to its proximity (z=0.07), its strong X-ray brightness and its giant cD galaxy which is one of the biggest stellar aggregates we know. We present...
Measuring Omega_0 with higher-order Quasar-Galaxy Correlations induced by Weak Lensing (2002)
Menard, Brice, Bartelmann, Matthias, Mellier, Yannick
Via the magnification bias, gravitational lensing by large-scale structures causes angular cross-correlations between distant quasars and foreground galaxies on angular scales of arc minutes and...
Cosmological Information from Quasar-Galaxy Correlations induced by Weak Lensing (2002)
Menard, Brice, Bartelmann, Matthias
The magnification bias of large-scale structures, combined with galaxy biasing, leads to a cross-correlation of distant quasars with foreground galaxies on angular scales of the order of arc minutes...
