SDSS IV MaNGA - An archaeological view of the Cosmic Star Formation History [link]Paper  abstract   bibtex   
We present the results of the archaeological analysis of the stellar populations of a sample of \textasciitilde4,000 galaxies observed by the SDSS-IV-MaNGA survey using Pipe3D. Based on this analysis we extract a sample of \textasciitilde150,000 SFRs and stellar masses that mimic a single cosmological survey covering the redshift range between z\textasciitilde0 to z\textasciitilde7. We confirm that the Star-Forming Main Sequence holds as a tight relation in this range of redshifts, and evolves strongly in both the zero-point and slope. This evolution is different for the population of local star-forming (SFGs) and retired (RGs) galaxies, with the latter presenting a stronger evolution in the zero-point and a weaker evolution in the slope. The fraction of RGs decreases rapidly with z, particularly for those classified as RGs at z\textasciitilde0. Contrary to previous studies we detect RGs well above z\textgreater1, although not all of them are progenitors of local RGs. Finally, adopting the required corrections to make the survey complete in mass in a limited volume, we recover the cosmic star-formation rate (SFR), stellar mass density, and average specific SFR histories of the Universe in this wide range of look-back times, with a remarkable agreement with the values reported by various cosmological surveys. We demonstrate that the progenitors of local RGs were more actively forming stars in the past, contributing to most of the cosmic SFR density at z\textgreater0.5, and to most of the cosmic stellar mass density at any redshift. They suffer a general quenching in the SFR at z\textasciitilde0.35. Below this redshift the progenitors of local SFGs dominate the SFR density of the Universe.
