| Abstract: |
Spectral energy distribution fitting is a powerful tool for estimating the parameters of distant galaxies and it is heavily influenced by a galaxy's star formation history. Much of the information of recent star formation is encoded in the ultraviolet range of the spectrum. Habitable Worlds Observatory has the potential to provide substantially improved ultraviolet information and care should be taken to choose photometric filters that will maximize the science that can be done. Here, mock photometry is used to study the \textit{GALEX} and \textit{Swift} UVOT filters ability to recover galaxy parameters. An additional run is conducted with the \textit{GALEX} FUV filter paired with the UVOT filters. We find that the wider wavelength coverage of \textit{GALEX} is important to constrain properties, while the UVOT filters offer improved recovery of dust parameters. A filter suite aboard HWO that combines similar filter properties will maximize its ability to inform future SED fitting. |
