The stellar fossil record of dE galaxies

Francesco La Barbera , Osservatorio Astronomico di Capodimonte

Dwarf elliptical galaxies (dEs) represent a fascinating class of systems, outnumbering other classes of galaxies in groups and clusters. Nevertheless, due to the faint surface brightness level of dEs, no much is known about their stellar population properties. I will present a stellar population study --- the most detailed one performed so far -- for the typical dE galaxy NGC1396, in the Fornax cluster. Thanks to the exquisite quality of VLT-MUSE IFU spectroscopy, we have studied a variety of optical and NIR absorption features at different galactocentric distances in NGC1396, to constrain (for the very first time) the star-formation history, metallicity content, chemical abundances, and stellar IMF, in this system. I will discuss how these results provide a unique imprint of the formation and evolution processes of dEs.
