![]() ![]() Her science is mainly focused on galaxies evolution. Our analysis has revealed that in the inner regions of these two clusters the vast majority of blue star-forming cluster members are predominantly ram-pressure stripped, suggesting that this mechanism was even more effective at intermediate redshift than in today’s universe.Īlessia Moretti is a researcher at the INAF-Osservatorio Astronomico di Padova, where she got her PhD in 2005 with a thesis on globular cluster systems in early-type galaxies. As in their low-redshift counterpart, emission-line properties as well as stellar features have been analyzed to infer the presence of this gas-only stripping mechanism, that produces spectacular ionized gas tails departing from the main galaxy body. In particular I will describe how we discovered and characterised 13 ram-pressure-stripped galaxies in the central regions of A2744 and A370 (z∼0.3-0.4), using the MUSE spectrograph. I will present the results of our search of ram-pressure stripped galaxies in this sample. MUSE IFU data are available for a sample of more distant (z∼0.3-0.5) clusters, with mosaics covering the inner cluster regions. The ionized gas emission traced by the OII doublet (in red) is superimposed over the RGB image constructed using HST imaging.Ībstract: Ram pressure stripping has been proven to be effective in shaping galaxy properties in dense environments at low redshift.
