Poster Title: No stars in Local Group High Velocity Clouds?
Abstract: To solve the dwarf galaxy crisis of hierarchical clustering, Blitz et al. proposed that compact high velocity clouds might be small dark matter halos belong to the local group. To test this hypothesis, we did VLT deep imaging to search for a stellar population of this small halos by photometry of a resolved stellar component. The test is sensitive for distances to >2 Mpc but did not reveal any population. We also used 2MASS data with a similar result and started to search for Planetary Nebulae. Our results are in excellent agreement with indepent similar results from surveying for LSB features towards CHVC and analysing the SDSS data base (Simon \& Blitz, 2002, Lewis et al. 2002, Willman et al 2002). We will put the results into a common observationl context.
