How well can we measure the stellar mass of a galaxy: the impact of the assumed star formation history model in SED fitting
The primary method for inferring the stellar mass (M*) of a galaxy is through spectral energy
distribution (SED) modeling. However, the technique rests on assumptions such as the …
