Ten years of continuous measurements of the radial velocity of the Sun have been used to estimate the contribution of various solar surface phenomena to the...

Spectrophotometric observations in the optical and near-infrared of six giant H II regions in the high metallicity spiral galaxy M51 are presented. Five of the...

Detailed spectrophotometry in the visual and near-infrared is presented for four different slit positions over the core of NGC 604. The excitation ([O II]/[O...

OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) is a NASA mission to return a sample of asteroid (101955)...

The authors have applied a new spectrophotometric stellar population synthesis model, designed to study early-type galaxies (Vazdekis, Casuso et al. 1995), to...

Calculations of atmospheric transmission through the M (5 microns) atmospheric window, at a resolution of 10 to the 3rd power are presented for sites at the...

The observations were made on 2003 March 29, 30 and 31 with UVES, at the VLT Kueyen Telescope in Cerro Paranal Observatory (Chile). We used the standard...

We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we...

An attempt is made to confirm the observation of Allen (1980) of a 3.3-micron emission feature attributed to thermal dust emission in the quasar 3C 273...
