Journal ArticleDOI

The Gaia mission

T. Prusti, +624 more
TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.
Journal ArticleDOI

Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties

Anthony G. A. Brown, +590 more
TL;DR: The first Gaia data release, Gaia DR1 as discussed by the authors, consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues.
Journal ArticleDOI

CALIFA, the Calar Alto Legacy Integral Field Area survey : I. Survey presentation

Sebastián F. Sánchez, +84 more
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.
Journal ArticleDOI

The Stellar Population Histories of Early-Type Galaxies. II. Controlling Parameters of the Stellar Populations

TL;DR: In this paper, single stellar population (SSP)-equivalent parameters for 50 local elliptical galaxies were analyzed as a function of their structural parameters, including velocity dispersions, radii, surface brightnesses, masses, and luminosities.
Journal ArticleDOI

The Stellar Population Histories of Local Early-Type Galaxies. I. Population Parameters

TL;DR: In this article, a series of investigations into the stellar populations of local elliptical galaxies as determined from their integrated spectra was conducted to determine the star formation and chemical evolution histories of present-day galaxies.
