SUMMARY:Globular cluster systems and the origin of early-type dwarfs in Vir
 go
DESCRIPTION:Globular cluster systems and the origin of early-type dwarfs in
  Virgo\nDr. Rubén Sánchez-Janssen\n\nEarly-type dwarfs (dEs) are by far 
 the most abundant galaxy population in nearby clusters. Whether these obje
 cts are primordial, or recent end-products of the different physical mecha
 nisms that can transform galaxies once they enter these high-density envir
 onments, is still a matter of debate. Here we present a novel approach to 
 test the latter scenario by comparing the properties of the globular clust
 er systems of dEs and their potential progenitors with simple predictions 
 from gravitational and hydrodynamical interactions. Current data in the li
 terature do not favour violent mechanisms, but gentle processes with long 
 timescales or that took place at the early stages of their formation.
