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...
Fitting peculiar spectral profiles in He I 10830Å absorption features
The new generation of solar instruments provides better spectral, spatial, and temporal resolution for a better understanding of the physical processes that...
Context. The nature of ultra-luminous X-ray (ULX) sources is still a matter of debate. Studies of their counterparts in other spectral ranges will help to...
Five young star clusters in the outer region of the Small Magellanic Cloud
Colour-magnitude diagrams in the Washington system are presented for the first time for five star clusters projected on to the outer region of the Small...
