THE SERENDIPITOUS OBSERVATION OF A GRAVITATIONALLY LENSED GALAXY AT<i>z</i>= 0.9057 FROM THE BLANCO COSMOLOGY SURVEY: THE ELLIOT ARC
We report on the serendipitous discovery in the Blanco Cosmology Survey (BCS) imaging data of a z = 0.9057 galaxy that is being strongly lensed by a massive galaxy cluster at a redshift of z=0.3838. The lens (BCS J2352-5452) was discovered while examining i- and z-band images being acquired in …
