Abstract:
With the aim of distinguishing between possible physical mechanisms
acting on galaxies when they fall into clusters, we study the
properties of the gas and the stars in a sample of 422 emission-line
galaxies from the European Southern Observatory Distant Cluster Survey
in different environments up to z∼1. We identify galaxies with
kinematical disturbances (from emission lines in their 2D spectra) and
find that they are more frequent in clusters than in the field.
