Abstract

We study 5 barred dwarf galaxies located in the Virgo cluster to understand the effect of the environment on the formation and evolution of their bars. We measure the properties of bars with different methods using MUSE data. In particular, we measure the bar pattern speed with the Tremaine-Weinberg method: a slowly-rotating bar is expected by the presence of a huge amount of DM or when the bar formation is driven by galaxy interaction. Dwarf galaxies are the best candidates to host slowly-rotating bars.
