Dark Matter Structures In The Deep Lens Survey (2008)
Kubo, Jeffrey M., Khiabanian, Hossein, Dell'Antonio, Ian P., Wittman, David, Tyson, J. Anthony
We present a regularized maximum likelihood weak lensing reconstruction of the Deep Lens Survey F2 field (4 deg^2). High signal-to-noise ratio peaks in our lensing significance map appear to be...
A method to search for strong galaxy-galaxy lenses in optical imaging surveys (2007)
Kubo, Jeffrey M., Dell'Antonio, Ian P.
We present a semi-automated method to search for strong galaxy-galaxy lenses in optical imaging surveys. Our search technique constrains the shape of strongly lensed galaxies (or arcs) in a...
The Mass Of The Coma Cluster From Weak Lensing In The Sloan Digital Sky Survey (2007)
Kubo, Jeffrey M., Stebbins, Albert, Annis, James, Dell'Antonio, Ian P., Lin, Huan, Khiabanian, Hossein, ...
We present a weak lensing analysis of the Coma Cluster using the Sloan Digital Sky Survey (SDSS) Data Release Five. Complete imaging of a ~ 200 square degree region is used to measure the tangential...
$\mu$--PhotoZ: Photometric Redshifts by Inverting the Tolman Surface Brightness Test (2007)
Kurtz, Michael J., Geller, Margaret J., Fabricant, Daniel G., Wyatt, William F., Dell'Antonio, Ian P.
Surface brightness is a fundamental observational parameter of galaxies. We show, for the first time in detail, how it can be used to obtain photometric redshifts for galaxies, the $\mu$-PhotoZ...
SHELS: The Hectospec Lensing Survey (2005)
Geller, Margaret J., Dell'Antonio, Ian P., Kurtz, Michael J., Ramella, Massimo, Fabricant, Daniel G., Caldwell, Nelson, ...
The Smithsonian Hectospec Lensing Survey (SHELS) combines a large deep complete redshift survey with a weak lensing map from the Deep Lens Survey (Wittman et al. 2002; 2005). We use maps of the...
Detailed Mass Map of CL0024+1654 from Strong Lensing (1998)
Tyson, J. Anthony, Kochanski, Greg P., Dell'Antonio, Ian P.
We construct a high resolution mass map of the z=0.39 cluster 0024+1654, based on parametric inversion of the associated gravitational lens. The lens creates eight well-resolved sub-images of a...
Galaxy Dark Matter: Galaxy-Galaxy Lensing in the Hubble Deep Field (1996)
Dell'Antonio, Ian P., Tyson, J. Anthony
In this Letter we present calibrated observations of the average mass of galaxies with 22< I < 25 in the Hubble Deep Field. We measure the mean mass profile using the statistical gravitational lens...
Kinematics and dynamics in large scale structure / (1995)
Thesis (Ph. D.)--Harvard University, 1995.
The Time Development of a Resonance Line in the Expanding Universe (1993)
Rybicki, George B., Dell'Antonio, Ian P.
The time-dependent spectral profile of a resonance line in a homogeneous expanding medium is studied by numerically solving an improved Fokker-Planck diffusion equation. The solutions are used to...
