GALEX Catalog of UV Point Sources in M33
  The hottest stars ($>$10,000 K), and by extension typically the most massive
ones, are those that will be prevalent in the ultraviolet (UV) portion of the
electromagnetic spectrum, and we expect numerous B, O, and Wolf-Rayet stars to
be bright in UV data. In this paper, we update the previous UV catalog of M33,
created using the Ultraviolet Imaging Telescope (UIT), using data from the
Galaxy Evolution Explorer (GALEX). We utilize PSF photometry to better handle
the crowded regions in the galaxy, and benefit from GALEX's increased
sensitivity compared to UIT. We match our detections with data from the Local
Group Galaxies Survey (LGGS) to create a catalog with photometry spanning from
the far-UV through the optical for a final list of 24738 sources. All of these
sources have far-UV (FUV; 1516A), near-UV (NUV; 2267A), and V data, and a
significant fraction also have U, B, R, and I data as well. We compare these
sources to a catalog of known Wolf-Rayet stars in M33 and find that we recover
114 of 206 stars with spatially-coincident UV objects. Additionally, we
highlight and investigate those sources with unique colors as well as a
selection of other well-studied sources in M33.
