TL;DR: In this article, the first conclusive evidence for cosmic deceleration that preceded the current epoch of cosmic acceleration was provided by the discovery of 16 Type Ia supernovae with the Hubble Space Telescope (HST).
Journal ArticleDOI

De Marchi,Holland C. Ford,Ronald L. Gilliland,George F. Hartig,Garth D. Illingworth,J. Mack,Wm. J. McCann +18 more
TL;DR: In this paper, the photometric calibration of the Advanced Camera for Surveys (ACS) was presented, and a significant amount of data has been collected to characterize the on-orbit performance of the three channels.

TL;DR: In this paper, the photometric calibration of the HST Advanced Camera for Surveys (ACS) is presented, and an overview of the performance and calibration of two CCD cameras, the Wide Field Channel (WFC) and the High Resolution Channel (HRC), and a description of the best techniques for reducing ACS CCD data.
Journal ArticleDOI
Bayesian Photometric Redshift Estimation
TL;DR: In this article, the authors proposed a Bayesian method for estimating the photometric redshift of a galaxy using prior probabilities and Bayesian marginalization, which is shown to be significantly more reliable than those obtained with maximum-likelihood techniques.
Journal ArticleDOI
