Simple Model to Estimate Stellar Masses in the Bright Galaxy Survey

This project provides a straightforward approach to estimating stellar masses for galaxies in the Bright Galaxy Survey (BGS) using both photometric and spectroscopic data. The models developed aim to improve the accuracy of stellar mass estimates.

The project employs measurements from the Dark Energy Spectroscopic Instrument (DESI) to develop and validate a model.
