We use a combination of deep optical and near-infrared light profiles for a morphologically diverse sample of Virgo cluster galaxies to study the radially resolved stellar populations of cluster galaxies over a wide range of galaxy structure. We find that, in the median, the age gradients of Virgo galaxies are either flat (lenticulars and Sa–Sb spirals) or positive (ellipticals, Sbc+Sc spirals, gas-rich dwarfs and irregulars), while all galaxy types have a negative median metallicity gradient… Expand
SDSS-IV MaNGA: global stellar population and gradients for about 2000 early-type and spiral galaxies on the mass-size plane
