SAM images gravitational arcs in the Abel 370 cluster of galaxies

14 Febrero 2014

Nearly every "star" in this image is actually a galaxy. The SOAR Adaptive Module (SAM), built by CTIO/NOAO-S, is mounted on the SOAR 4.1 meter telescope: it creates an artificial laser guide star which enables the exquisite resolution seen here. The dark shadow on the left ( as seen in the full image) is produced by the SAM guide probe. Data were taken in September 2013 for the SAM science verification proposal by D. Caminha et al.
