A novel data-driven approach to extract stellar population properties from galaxy spectra using absorption indices
Zahra Sharbaf, Ignacio Ferreras, Anna R. Gallazzi +4
In an era of highly complex machine learning methods that often are informative but not straightforward to interpret, Principal Component Analysis (PCA) offers a simple, easily int…
Correcting the fiber-aperture bias affecting galaxy stellar populations in the Sloan Digital Sky Survey. Aperture corrections to absorption indices based on CALIFA integral field observations
Stefano Zibetti, Jacopo Pratesi, Anna R. Gallazzi +2
Stellar population properties are crucial for understanding galaxy evolution. Their inference for statistically representative samples requires deep multi-object spectroscopy, typi…
Spatially resolved stellar-to-total dynamical mass relation: Radial variations, gradients and profiles of galaxy stellar populations
L. Scholz-Diaz, A. R. Gallazzi, S. Zibetti +1
Although galaxy evolution is governed by the interplay between baryonic physics and dark matter halo assembly, how halo properties shape observed galaxies remains unclear. With cur…
Archaeological investigation of galaxies' evolutionary history in the cosmic middle ages
Anna R. Gallazzi, Stefano Zibetti, Mark Sargent +14
The cosmic Middle Ages, spanning the last 8-10 Gyr of the Universe, is a critical period in which massive early-formed systems coexist with global star formation quenching in less…
LEGA-C stellar populations scaling relations. II: Dissecting mass-complete archaeological trends and their evolution since z~0.7 with LEGA-C and SDSS
Anna R. Gallazzi, Stefano Zibetti, Arjen van der Wel +11
With a sample of 552 galaxies at z~0.7 from the LEGA-C survey, we investigate how current star formation influences light-weighted mean stellar ages and metallicities, and their me…
Re-assessing the stellar population scaling relations of the galaxies in the Local Universe
D. Mattolini, S. Zibetti, A. R. Gallazzi +2
Local galaxies follow scaling relations between mass and stellar population properties such as age and metallicity, which encode key information on their evolutionary histories. We…
