Photometric Redshift Estimation

Photometric redshift estimation is a method that infers the redshift values of celestial objects through their multi-band photometric data. This method aims to utilize the radiation characteristics of galaxies in different bands, establishing a relationship model between photometry and redshift, thereby achieving efficient estimation of redshifts for a large number of celestial objects. Photometric redshift estimation has significant application value in cosmological research, providing crucial data support for large-scale structure analysis, galaxy evolution studies, and dark energy detection.
