Abstract
The far ultraviolet background images from the Galaxy Evolution Explorer were used
to examine the reported diffuse 1056 K gas component in galaxy clusters. To remove
the scattered starlight from dust component to the UV background the 100 micron
images of Schlegel, Finkbeiner, and Davis were used. No confirmations are reported,
with upper limits on the UV flux 1015 erg s1 cm2 °A1. This is many orders of
magnitude above what would be expected from a blackbody at 107 K. The upper limits
on ultraviolet flux are compared with ultraviolet emission from elliptical galaxies and
the cluster’s X-ray luminosity. The inability to completely remove the dust component
and the presence of residual emission from bright galaxies limited the results.
