TL;DR: In this paper, the extinction-corrected H$\alpha$ star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks) was estimated using a multi-component photometric decomposition based on SDSS imaging to CALIFA Integral Field Spectroscopy data.
Journal ArticleDOI
Self-similarity in the chemical evolution of galaxies and the delay time distribution of SNe Ia
C. J. Walcher,Robert M. Yates,Ivan Minchev,Cristina Chiappini,Maria Bergemann,Gustavo Bruzual,Stephane Charlot,Paula Coelho,Anna Gallazzi,Marie Martig +9 more
TL;DR: In this paper, the authors compare the relation between age and alpha-element abundances for stars in the solar neighborhood to that of local, early-type galaxies and find both relations to be very similar.
Journal ArticleDOI

Christian Marinoni,Amelie Saintonge,T. Contini,C. J. Walcher,R. Giovanelli,Martha P. Haynes,K. L. Masters O. Ilbert,A. Iovino,V. Le Brun,O. Le Fevre,Alain Mazure,L. Tresse,J. M. Virey,S. Bardelli,D.

TL;DR: In this article, the angular diameter-redshift and Hubble diagrams are applied to the same sample of objects (i.e., velocity selected galactic discs) to derive a characteristic chart, the cosmology-evolution diagram, mapping the relation between global cosmological parameters and local structural parameters of discs such as size and luminosity.

TL;DR: WEAVE as discussed by the authors is a massively multiplexed spectroscopic survey facility for the William Herschel Telescope that will see first light in late 2022, and consists of a 2-degree field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable integral field units (IFUs), and a single large IFU.
