Stellar density maps (top), mock SDSS, and JWST composite images (middle and bottom) of various objects in NEWCLUSTER. From left to right, images display the brightest cluster galaxy, tidal feature, and low-surface brightness galaxy samples. The sources from earlier snapshots are included to express the high-z background objects, and we also consider the k-correction to generate mock observations. Mock SDSS and JWST images are a composite of r, i, and z filters to cover the JWST range. We arbitrarily add a sky noise corresponding to 24 and 31 mag arcsec⁻¹ for SDSS and JWST, respectively. The point spread functions are convolved with the pixelized source images.
