Abstract

Observing high-redshift objects provides a window into the past, enabling insight into galaxy formation, matter distribution, and the nature of dark matter and energy. This report presents a sample of work on Cycle 1 of the James Webb Space Telescope concerning the discovery of high-redshift early galaxy candidates. Potential objects from these surveys had their photometric redshift computed using the LePhare simulation program and analysed using LePhare-generated spectral energy distribution fits. A total of 46 candidates at redshifts beyond z > 9.5 were found between three surveys: two in DDT2750, 30 in JADES, and 14 in NGDEEP.
