Dating the formation of the counter-rotating stellar disc in the spiral galaxy NGC 5719 by disentangling its stellar populations

Abstract: We present the results of the VLT/VIMOS integral-field spectroscopicobservations of the inner 28"x28" (3.1 kpc x 3.1 kpc) of the interacting spiralNGC 5719, which is known to host two co-spatial counter-rotating stellar discs.At each position in the field of view, the observed galaxy spectrum isdecomposed into the contributions of..
