The Advanced Gamma‐ray Imaging System (AGIS)—Simulation Studies

The Advanced Gamma‐ray Imaging System (AGIS) is a US‐led concept for a next‐generation instrument in ground‐based very‐high‐energy gamma‐ray astronomy. The most important design requirement for AGIS is a sensitivity of about 10 times greater than current observatories like Veritas, H.E.S.S or MAGIC. We present results of simulation studies of various possible designs for AGIS. The primary characteristics of the array performance, collecting area, angular resolution, background rejection, and sensitivity are discussed.
