The Sloan Digital Sky Survey III (SDSS-III) Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a three-year survey that is collecting 105 high-resolution spectra in the near-IR across multiple Galactic populations. To derive stellar parameters and chemical compositions from this massive data set, the APOGEE Stellar Parameters and

The Calar Alto Large Integral Field Area Survey (CALIFA) is a recently started survey with the main aims at observing a statistically well-defined sample of ˜ 600 galaxies in the local universe with the PMAS/PPAK integral field spectrophotometer on the 3.5 m telescope at the CAHA. The main goal of this survey is to characterize the spatially

A detailed study of the spiral galaxy UGC9837 is carried out based on the IFU spectroscopic data from the pilot survey of the Calar Alto Legacy Field Survey (CALIFA). The integrated, radial and spatially resolved properties of the ionized gas are studied. In addition the possible biases caused by using a fixed aperture in studying galaxy properties

We present here the Calar Alto Legacy Integral Field spectroscopy Area survey (CALIFA). CALIFA is large collaboration comprising more than 50 astronomers of 8 different countries, which main aim is to obtain detailed spatially resolved spectroscopic information of ˜ 600 galaxies of any type at the Local Universe (0.005

Context: Free-floating substellar candidates with estimated theoretical masses of as low as ∼5 Jupiter masses have been found in the ∼3 Myr old σ Orionis open cluster. As the overlap with the planetary mass domain increases, the question of how these objects form becomes important. The determination of their number density and whether a mass cut

The San Fernando automatic meridian circle (CMASF) is a meridian telescope built by Grubb-Parsons in 1948 fully automated between 1987 and 1995. In 1996 was moved from the Real Instituto y Observatorio de la Armada (ROA) in San Fernando to the Carlos U. Cesco (CUC) mountain observatory in San Juan (Argentine). The CUC is owned by the Observatorio
