cds-question@unistra.frgalaxiesgalaxy-classification-systemssurface-photometryNew surface photometry of all known elliptical galaxies in the Virgo cluster is combined with published data to derive composite profiles of brightness, ellipticity, position angle, isophote shape, and color over large radius ranges. These provide enough leverage to show that Sersic logI{prop.to}r^1/n^ functions fit the brightness profiles I(r) of nearly all ellipticals remarkably well over large dynamic ranges. Therefore, we can confidently identify departures from these profiles that are diagnostic of galaxy formation. Finally, we verify that there is a strong dichotomy between elliptical and spheroidal galaxies. Their properties are consistent with our understanding of their different formation processes: mergers for ellipticals and conversion of late-type galaxies into spheroidals by environmental effects and by energy feedback from supernovae.2009ApJS..182..216Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/182/216CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/39 : Bibliography of Surface Photometry of galaxies (Davoust+ 1982)VII/176 : Elliptical galaxies photometry and spectroscopy (Faber+ 1989)J/AJ/108/1598 : Virgo cluster ellipticals.
