Laboratoire Dynamique des Etoiles, des (Exo)-planètes, et de leur environnement

Thanks to an abundance of excellent observational data the evolution of the population of galaxies in terms of its stellar mass function, the distribution of star-formation across galaxies and their structural properties is known with good precision. The challenge we face, though, is to decipher the evolutionary paths of individual galaxies. Two roads to achieving this goal are 1) to reconstruct star-formation histories of individual galaxies through detailed modeling of high-quality spectra, and 2) attempt to define 'rules' for galaxy evolution that tell us how the collection of individual galaxies must evolve so that the population properties are reproduced. I will describe our recent progress along these lines, enabled by high-quality data from VLT spectroscopy of z~1 galaxies (the LEGA-C survey) and high-quality imaging data from HST (CANDELS) and JWST (CEERS).
