Abstract

We report the discovery of four very bright, strongly-lensed galaxies found via systematic searches for arcs in Sloan Digital Sky Survey Data Release 5 and 6. These were followed-up with spectroscopy and imaging data from the Astrophysical Research Consortium 3.5m telescope at Apache Point Observatory and found to have redshift z>2.0z>2.0. With isophotal magnitudes r=19.220.4r = 19.2 - 20.4 and 3\arcsec3\arcsec-diameter magnitudes r=20.020.6r = 20.0 - 20.6, these systems are some of the brightest and highest surface brightness lensed galaxies known in this redshift range. In addition to the magnitudes and redshifts, we present estimates of the Einstein radii, which range from 5.0\arcsec5.0 \arcsec to 12.7\arcsec12.7 \arcsec, and use those to derive the enclosed masses of the lensing galaxies.
