We propose the Cosmic Evolution Early Release Science (CEERS) Survey, which covers 100 sq. arcmin with JWST imaging and spectroscopy, and is designed to achieve the DD-ERS goals. CEERS will inform the selection of a wide variety of spectroscopic targets for Cycle 2 with a practical choice of imaging area, depth, and wavelength coverage, targeting a field that is supported by a rich set of HST/CANDELS multi-wavelength data.
CEERS will demonstrate, test, and validate efficient extragalactic surveys with coordinated, overlapping parallel observations with the JWST instrument suite, including NIRCam and MIRI imaging, NIRSpec R~100 and R~1000 spectroscopy, and NIRCam slitless grism (R~1500) spectroscopy. These tests enable Cycle 2 observations, including validating JWST parallel observing modes, dither and exposure-time strategies, and spectroscopic observing modes including slit-loss corrections.
CEERS enables immediate community science into both extragalactic JWST science drivers “First Light and Reionization” and “The Assembly of
- The discovery of 20-80 galaxies at z~9-13, constraining their abundance and physical nature;
- Deep spectra of >400 galaxies at z>3, including 40 known candidates at 6<z<9, enabling redshifts and constraints on physical conditions of star-formation and black hole growth via line diagnostics;
- Quantifying the first bulge and disk structures at z>3; and
- Characterizing galaxy mid-IR emission to study dust-obscured star-formation and supermassive black hole growth at z~1-3.
The CEERS collaboration is diverse on many axes with demonstrated expertise in rapid delivery of high-level science products.
NIRCam: Wide Field Slitless Spectroscopy; Imaging
NIRSpec: Multi-object Spectroscopy
- Science: 1-5um imaging over 100 arcmin^2, 5-20 um imaging over 2-4 MIRI fields, 1-5um NIRSpec R~100 and R~1000 slit spectroscopy over ~300 galaxies, and slitless NIRCam spectroscopy over ~40 arcmin^2.
- Data: Rapid reduction and release prior to Cycle 2 call; first catalogs released six months after data acquisition.
- Technical: Validate coordinated parallel strategies; empirically measure NIRSpec MSA slit losses.
