Abstract. One of the more interesting studies to be performed with TAU- VEX will be an unbiased survey of galaxies. Since the TAUVEX flight will occur when most of the results from GALEX will have been made available to the scientific community, it is important to select those types of studies that will extend significantly those done by GALEX and will complement them. We present three different pro jects to be attempted in the field of galaxy UV observations: a general survey aimed at understanding the stellar popula- tions in galaxies in a variety of environments based on deep TAUVEX expo- sures that should reach deeper than the GALEX mid-depth survey, a specific targeting of sky regions covered by HI measurements in order to detect the UV emission from low surface brightness galaxies detected through their 21-cm emission, and a unique pro ject to measure the extragalactic extinction law by imaging early-type galaxies with dust lanes.
