TL;DR: The Calar Alto Legacy Integral Field Area (CALIFA) survey as discussed by the authors was designed to provide a first step in this direction by obtaining spatially resolved spectroscopic information of a diameter selected sample of similar to 600 galaxies in the Local Universe.

TL;DR: In this article, the authors analyzed the total HI contents of 72 Hickson compact groups of galaxies and detailed spatial distributions and kinematics of HI within a subset of 16 groups using the high angular resolution observations obtained with the VLA in order to investigate a possible evolutionary scenario for these densest systems in the present day galaxy hierarchy.

TL;DR: In this paper, the authors describe the selection procedure and statistical properties of the galaxy sample used by the Calar Alto Legacy Integral Field Area (CALIFA) survey, a public legacy survey of 600 galaxies using integral field spectroscopy.

TL;DR: The first public data release (DR1) of the Calar Alto Legacy Integral Field Area (CALIFA) survey is presented in this article, which consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005 < z < 0.03) galaxies, obtained with the integral field spectrograph PMAS/PPak mounted on the 3.5 m telescope at the Calal Alto observatory.

TL;DR: In this article, the authors apply the fossil record method based on spectral synthesis techniques to recover the following physical properties for each spatial resolution element in the target galaxies: the stellar mass surface density (μ_*), stellar extinction (A_V), lightweighted and mass-weighted ages (L, M), and mass weighted metallicity (M).
