Weak Lensing Results from the 75 Square Degree CTIO Survey
M. Jarvis, G. Bernstein, B. Jain +4
We measure seeing-corrected ellipticities for 2 x 10^6 galaxies with magnitude R<23 in 12 widely separated fields totalling 75 deg^2 of sky. At angular scales >30\arcmin, elliptici…
Weak Lensing Measurements of 42 SDSS/RASS Galaxy Clusters
Erin Scott Sheldon, James Annis, Hans Bohringer +21
We present a lensing study of 42 galaxy clusters imaged in Sloan Digital Sky Survey (SDSS) commissioning data. Cluster candidates are selected optically from SDSS imaging data and…
Weak Lensing Determination of the Mass in Galaxy Halos
D. R. Smith, G. M. Bernstein, P. Fischer +1
We detect the weak gravitational lensing distortion of 450,000 background galaxies (20<R<23) by 790 foreground galaxies (R<18) selected from the Las Campanas Redshift Survey (LCRS)…
The Normal Cluster Weak Lensing Survey: Mass Profiles and M/L Ratios of Eight Clusters at z=0.2
David Wittman, Ian Dell'Antonio, Tony Tyson +3
We present a survey of mass profiles and mass-to-light ratios of eight typical galaxy clusters at a common redshift (z ~ 0.2). We use weak gravitational lensing as a probe because…
Weak Lensing with SDSS Commissioning Data: The Galaxy-Mass Correlation Function To 1/h Mpc
SDSS Collaboration, Fischer
(abridged) We present measurements of galaxy-galaxy lensing from early commissioning imaging data from the Sloan Digital Sky Survey (SDSS). We measure a mean tangential shear aroun…
Values of H_0 from Models of the Gravitational Lens 0957+561
Gary Bernstein, Philippe Fischer
The lensed double QSO 0957+561 has a well-measured time delay and hence is useful for a global determination of H0. Uncertainty in the mass distribution of the lens is the largest…
