Young stellar populations from NUV spectroscopy in massive early-type galaxies
Massive early-type galaxies (ETGs) are mainly populated by old stars that dominate the optical spectral range. We analyse optical and near-ultraviolet (NUV) absorption lines from integrated spectra of massive ETGs to study its young stellar content, thanks to the extreme sensitivity of the NUV to young stars. We find that young stellar populations
