J/ApJ/600/L155      Gravitational lens in GOODS ACS fields   (Fassnacht+, 2004)

Strong gravitational lens candidates in the GOODS ACS fields. Fassnacht C.D., Moustakas L.A., Casertano S., Ferguson H.C., Lucas R.A., Park Y. <Astrophys. J., 600, L155-L158 (2004)> =2004ApJ...600L.155F

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 true-color 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. Description: All candidate selection was done using the ACS data obtained in the F435W, F606W, F775W, and F850LP filters (hereafter B435 (Bmag), V606 (Vmag), i775 (Imag), and z850 (Zmag), respectively).
