1204.2830 (Christopher B. Morrison et al.)

Tomographic Magnification of Lyman Break Galaxies in The Deep Lens Survey    [PDF]

Christopher B. Morrison, Ryan Scranton, Brice Ménard, Samuel J. Schmidt, J. A. Tyson, Russell Ryan, Ami Choi, David Wittman
Using about 450,000 galaxies in the Deep Lens Survey, we present a detection of the gravitational magnification of z>4 Lyman Break Galaxies by massive foreground galaxies with 0.49\sigma\ and is found to be consistent with the expected redshift-dependence of the WMAP7 \Lambda CDM cosmology.
