Strong Gravitational Lens Candidates in the Goods Acs Fields

چکیده

We present results from a systematic search for strong gravitational lenses in the GOODS ACS data. The search technique involves creating a sample of likely lensing galaxies, which we define as massive early-type galaxies in a redshift range 0.3 < z < 1.3. The target galaxies are selected by color and magnitude, giving a sample of 1092 galaxies. For each galaxy in the sample, we subtract a smooth description of the galaxy light from the z850-band data. The residuals are examined, along with truecolor images created from the B435V606i775 data, for morphologies indicative of strong lensing. We present our six most promising lens candidates, as well as our full list of candidates. Subject headings: galaxies: general — galaxies: high-redshift — gravitational lensing — surveys

The Sloan Lens Acs Survey . V . the Full Acs Strong - Lens Sample

We present the definitive data for the full sample of 131 strong gravitational lens candidates observed with the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope by the Sloan Lens ACS (SLACS) Survey. All targets were selected for higher-redshift emission lines and lowerredshift continuum in a single Sloan Digital Sky Survey (SDSS) spectrum. The foreground galaxies are primari...

Enhanced Lensing Rate by Clustering of Massive Galaxies: Newly Discovered Systems in the Slacs Fields

Galaxy-scale strong gravitational lens systems are useful for a variety of astrophysical applications. However, their use is limited by the relatively small samples of lenses known to date. It is thus important to develop efficient ways to discover new systems both in present and forthcoming datasets. For future large high-resolution imaging surveys we anticipate an ever-growing need for effici...

Galaxy Number Counts and Implications for Strong Lensing

We compare galaxy number counts in Advanced Camera for Surveys (ACS) fields containing moderate-redshift (0.2 < z < 1.0) strong gravitational lenses with those in two comparison samples: (1) the first square degree of the COSMOS survey, comprising 259 ACS fields and (2) 20 “pure parallel” fields randomly located on the sky. Through a Bayesian analysis we determine the expectation values (μ0) an...

A New Spectroscopically Selected Gravitational Lens

We present Gemini integral-field unit (IFU) spectroscopy and Hubble Space Telescope (HST) F435Wand F814W-band images of a newly discovered four-image gravitational lens, SDSSJ140228.22+632133.3 (hereafter SDSSJ1402). The system was identified as one of 49 gravitational-lens candidates in the luminous red galaxy sample of the Sloan Digital Sky Survey, based on higher-redshift emission lines in t...

The Sloan Lens Acs Survey. I. a Large Spectroscopically Selected Sample of Massive Early-type Lens Galaxies

The Sloan Lens ACS (SLACS) Survey is an efficient Hubble Space Telescope (HST) Snapshot imaging survey for new galaxy-scale strong gravitational lenses. The targeted lens candidates are selected spectroscopically from within the Sloan Digital Sky Survey (SDSS) database of galaxy spectra for having multiple nebular emission lines at a redshift significantly higher than that of the SDSS target ga...
