Modeling and Correcting the Time-Dependent ACS PSF (2009)

A. M. Koekemoer, P. Goudfrooij, L. L. Dressel, Jason Rhodes, Richard Massey, Justin Albert, ...

Abstract. The ability to accurately measure the shapes of faint objects in images taken with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST) depends upon detailed knowledge...

Pixel-based correction for Charge Transfer Inefficiency in the Hubble Space Telescope Advanced Camera for Surveys (2009)

Massey, Richard, Stoughton, Chris, Leauthaud, Alexie, Rhodes, Jason, Koekemoer, Anton, Ellis, Richard, ...

Charge Transfer Inefficiency (CTI) due to radiation damage above the Earth's atmosphere creates spurious trailing in Hubble Space Telescope (HST) images. Radiation damage also creates unrelated warm...

First catalog of strong lens candidates in the COSMOS field (2008)

Faure, Cecile, Kneib, Jean-Paul, Covone, Giovanni, Tasca, Lidia, Leauthaud, Alexie, Capak, Peter, ...

We present the first catalog of 67 strong galaxy-galaxy lens candidates discovered in the 1.64 deg^2 Hubble Space Telescope COSMOS survey. Twenty of these systems display multiple images or strongly...

Faure, Cecile, Kneib, Jean-Paul, Covone, Giovanni, Tasca, Lidia, Leauthaud, Alexie, Capak, Peter, ...

We present the first catalog of 67 strong galaxy-galaxy lens candidates discovered in the 1.64 square degree Hubble Space Telescope COSMOS survey. Twenty of these systems display multiple images or...

COSMOS: 3D weak lensing and the growth of structure (2007)

Massey, Richard, Rhodes, Jason, Leauthaud, Alexie, Capak, Peter, Ellis, Richard, Koekemoer, Anton, ...

We present a three dimensional cosmic shear analysis of the Hubble Space Telescope COSMOS survey, the largest ever optical imaging program performed in space. We have measured the shapes of galaxies...

The Stability of the Point Spread Function of the Advanced Camera for Surveys on the Hubble Space Telescope and Implications for Weak Gravitational Lensing (2007)

Rhodes, Jason D., Massey, Richard, Albert, Justin, Collins, Nicholas, Ellis, Richard S., Heymans, Catherine, ...

(abridged) We examine the spatial and temporal stability of the HST ACS Wide Field Camera (WFC) point spread function (PSF) using the two square degree COSMOS survey. We show that stochastic aliasing...

Dark matter maps reveal cosmic scaffolding (2007)

Massey, Richard, Rhodes, Jason, Ellis, Richard, Scoville, Nick, Leauthaud, Alexie, Finoguenov, Alexis, ...

Ordinary baryonic particles (such as protons and neutrons) account for only one-sixth of the total matter in the Universe. The remainder is a mysterious "dark matter" component, which does not...

Modelling and Correcting the Time-Dependent ACS PSF (2005)

Rhodes, Jason, Massey, Richard, Albert, Justin, Taylor, James E., Koekemoer, Anton, Leauthaud, Alexie

The ability to accurately measure the shapes of faint objects in images taken with the Advanced Camera for Surveys(ACS) on the Hubble Space Telescope (HST) depends upon detailed knowledge of the...
