We present the first stellar spectroscopy in the low-luminosity (MV ˜ -9.3 mag), dwarf galaxy Leo P. Its significantly low oxygen abundance (3% solar) and...
The V-type asteroids are of major scientific interest as they may sample multiple differentiated planetesimals. Determination of their physical properties is...
First survey of Wolf-Rayet star populations over the full extension of nearby galaxies observed with CALIFA
The search of extragalactic regions with conspicuous presence of Wolf-Rayet (WR) stars outside the Local Group is challenging task owing to the difficulty in...
Aims: The aim of the project is to improve our current knowledge of the density of T dwarfs and the shape of the substellar initial mass function by identifying...
First tentative detection of anisotropy in the QSO distribution around nearby edge-on spiral galaxies
Aims:To check whether the polar angle distribution of QSOs around nearby spiral galaxies is isotropic or not. Methods: A statistical analysis of the polar angle...
First View of the Solar Core from GOLF Acoustic Modes
After 8 months of nearly continuous measurements the GOLF instrument, aboard SOHO, has detected acoustic mode frequencies of more than 100 modes, extending from...
FIRTEZ-dz. A forward and inverse solver of the polarized radiative transfer equation under Zeeman regime in geometrical scale
We present a numerical code that solves the forward and inverse problem of the polarized radiative transfer equation in geometrical scale under the Zeeman...
Fitting Liner Nuclei within the Active Galactic Nucleus Family: A Matter of Obscuration?
In this paper, we study the nuclear obscuration of galaxies hosting low ionization narrow emission regions (LINERs) based on their X-ray and optical emission...
With data from Pantheon, we have at our disposal a sample of more than a 1000 supernovae Ia covering a wide range of redshifts with good precision. Here, we...
