A Multi-Resolution Weak Lensing Mass Reconstruction Method (2008)
Khiabanian, H., Dell'Antonio, I. P.
Motivated by the limitations encountered with the commonly used direct reconstruction techniques of producing mass maps, we have developed a multi-resolution maximum-likelihood reconstruction method...

The Big Throughput Camera (BTC) recently celebrated its first anniversary as a user instrument on the Blanco 4-meter telescope at Cerro Tololo Interamerican Observatory (CTIO), where it collects more...
Wittman, D., Dell'Antonio, I. P., Hughes, J. P., Margoniner, V. E., Tyson, J. A., Cohen, J. G., ...
We present the first sample of galaxy clusters selected on the basis of their weak gravitational lensing shear. The shear induced by a cluster is a function of its mass profile and its redshift...
The Deep Lens Survey Transient Search I : Short Timescale and Astrometric Variability (2004)
Becker, A. C., Wittman, D. M., Boeshaar, P. C., Clocchiatti, A., Dell'Antonio, I. P., Frail, D. A., ...
We report on the methodology and first results from the Deep Lens Survey transient search. We utilize image subtraction on survey data to yield all sources of optical variability down to 24th...
Wittman, D., Tyson, J. A., Dell'Antonio, I. P., Becker, A. C., Margoniner, V. E., Cohen, J., ...
The Deep Lens Survey (DLS) is a deep BVRz' imaging survey of seven 2x2 degree fields, with all data to be made public. The primary scientific driver is weak gravitational lensing, but the survey is...
Weak Lensing Discovery and Tomography of a Cluster at z=0.68 (2002)
Wittman, D., Margoniner, V. E., Tyson, J. A., Cohen, J. G., Dell'Antonio, I. P., Becker, A. C.
We report the weak lensing discovery, spectroscopic confirmation, and weak lensing tomography of a massive cluster of galaxies at $z=0.68$, demonstrating that shear selection of clusters works at...
Discovery of a Galaxy Cluster via Weak Lensing (2001)
Wittman, D., Tyson, J. A., Margoniner, V. E., Cohen, J. G., Dell'Antonio, I. P.
We report the discovery of a cluster of galaxies via its weak gravitational lensing effect on background galaxies, the first spectroscopically confirmed cluster to be discovered through its...
X-Ray and Optical Properties of Groups of Galaxies (1994)
Dell'Antonio, I. P., Geller, M. J., Fabricant, D. G.
We examine the relationship between the group x-ray luminosity in the 0.3-3.5 keV band and the measured velocity dispersion, and galaxy surface number density. We find definite correlations. Richer...
