ISOCAM 15 Micron Search for Distant Infrared Galaxies Lensed by Clusters

Abstract
In a search for lensed infrared galaxies, ISOCAM images have been obtained toward the rich clusters Abell 2218 and Abell 2219 at 15 μm. Nine galaxies (four in Abell 2218 and five in Abell 2219) were detected with flux levels in the range 530–1100 μJy. Three of the galaxies detected in Abell 2218 have previously known redshifts; of these one is a foreground galaxy, and the other two are lensed background galaxies at z = 0.474 and z = 1.032. One of the objects detected in the field of Abell 2219 is a faint, optically red, extreme infrared-dominated galaxy with a probable redshift of 1.048.
