Recent studies show evidence of galaxy pre-processing within groups and/or filaments before infall in galaxy clusters. We present VIMOS/IFU observations of IC1370, a galaxy that shows morphological signatures of a recent merger and is located at a projected distance of ˜1.2 Mpc to the center of the cluster II Zw108 at z ˜ 0.05. This galaxy shows two opposite tidal tails, a boxy bulge with a de Vaucouleurs light profile, and a disk component that contributes ˜50 % of the total luminosity. We investigate the history of the galaxy by applying the spectral synthesis technique to the integral field observations and combining the resulting information with morphological and photometric parameters. The same observations allow us to investigate a background (z ˜ 0.09) compact group of 6 galaxies, of which IC 1370 was initially thought to be the central, brightest member.
Based on observations collected at the European Southern Observatory (ESO) under programmes 076.B-0764(A) and 63.N-0737(A).
