LEGA-C: stellar population gradients 7 Gyr ago
Abstract
The LEGA-C survey is a large deep spectroscopy survey of the Universe at a lookback time of 7 Gyr. We use partially-resolved spatial information to present the first study of spatially-resolved stellar population properties on a statistically significant sample in the distant Universe. We show that i) post-starburst galaxies at z=1 show inverse age gradients, consistent with the effect of a central starburst and ii) star-forming galaxies show strong metallicity gradients, consistent with what is observed in the local Universe.
