Data pubblicazione: | 2018 | Titolo del volume in cui è pubblicato il poster: | VST in the Era of the Large Sky Surveys | Da pagina:: | 43 | Abstract: | Groups are key to understand the galaxy evolution: they contain most of the galaxies in Universe at present day, most of the stellar mass and have their own way to transform galaxies from active to passive. Our aim is understanding the mechanisms driving the co-evolution of galaxies in nearby groups. Rich of early-type galaxies showing shells and FUV bright rings, Dorado is a nearby (16.9 Mpc Firth et al. 2006, MNRAS, 372, 1856) loose (about 10 deg2 , Carrasco et al 2001, AJ, 121, 148) association still non-virialized, likely a way station towards rich, virialized groups. We are mapping the group via deep VST g, r SDSS filters and (hopefully) Astrosat-UVIT; Far and Near UV imaging from GALEX and Swift-UVOT are also available. Our targets include the giant earlytype galaxies (ETGs) marking the group backbone as well as their intermediate companions and dwarfs whose luminosity function is still largely incomplete. The optical and Far UV analysis is shedding light on the Dorado evolving phase, showing residual star formation in evolved giant ETGs. | Titolo del convegno: | VST in the Era of the Large Sky Surveys | Luogo del convegno: | Osservatorio di Capodimonte, Napoli | Periodo del convegno: | 5-8 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/27834 | URL: | https://indico.ict.inaf.it/event/549/ https://zenodo.org/record/1304773#.X4hCpu1S-Uk |
