Description
The MIRI instrument onboard JWST is changing our understanding of extragalactic astronomy, thanks to its unprecedented sensitivity and angular resolution. The Cosmic Evolution Early Release Science Survey (CEERS) JWST program has a total of 8 MIRI imaging pointings in the EGS field. All of the MIRI observations have been performed, and we have reduced the data (Yang et al. 2023). Based on these data, we have performed various scientific investigations about galaxy star formation, stellar mass, mid-IR morphology, and active galactic nuclei (AGN). We have an even larger MIRI program, MIRI EGS Galaxy and AGN Survey (MEGA), which has been approved in JWST Cycle 2. MEGA will bring us new MIRI data of 26 pointings also in the EGS field (tracing the existing NIRCam coverage). All pointings will have four filters F770W, F1000W, F1500W, and F2100W. We expect exciting scientific results to come out based on the MEGA+CEERS dataset.
