Identification of a Galaxy Cluster at z=3 with NIRCam Photometric Redshifts

This study presents the identification of a galaxy cluster at redshift z=3 utilizing the NIRCam instrument. We analyze photometric redshifts across various filters, including 500, 450, 400, 350, and more, to construct a detailed view of the cluster's properties and composition. The characterization of the cluster at such a high redshift is crucial for understanding galaxy formation and evolution in the early universe. Results indicate significant clustering at high redshifts, providing valuable insights into cosmic structure formation.
