Observan cómo se alimenta el agujero negro de Andrómeda
Un equipo científico internacional, liderado por la Universidad Observatorio de Munich y el Instituto de Astrofísica de Canarias, obtiene una visualización...
Observan una gran corriente de marea en la galaxia del Sombrero
Según el modelo cosmológico más actualizado, las grandes galaxias espirales como la Vía Láctea crecieron absorbiendo galaxias menores en una especie de...
Observational constraints to boxy/peanut bulge formation time
Boxy/peanut bulges are considered to be part of the same stellar structure as bars and both could be linked through the buckling instability. The Milky Way is...
Observational Evidence for a Correlation Between Macroturbulent Broadening and Line-profile Variations in OB Supergiants
The spectra of O and B supergiants (Sgs) are known to be affected by a significant form of extra line broadening (usually referred to as macroturbulence) in...
Observational hints of radial migration in disc galaxies from CALIFA
Context. According to numerical simulations, stars are not always kept at their birth galactocentric distances but they have a tendency to migrate. The...
Observing and Reducing IFUs: INTEGRAL and PMAS—Properties of the Ionized Gas in HH 202
The reduction of integral field spectroscopy (IFS) data requires several stages and many repetitive operations to convert raw data into, typically, a large...
Observing the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline
We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of six...
OCCASO - II. Physical parameters and Fe abundances of red clump stars in 18 open clusters
Open clusters have long been used to study the chemodynamical evolution of the Galactic disc. This requires a homogeneously analysed sample covering a wide...
OCCASO - III. Iron peak and α elements of 18 open clusters. Comparison with chemical evolution models and field stars
The study of open-cluster chemical abundances provides insights on stellar nucleosynthesis processes and on Galactic chemo-dynamical evolution. In this paper we...
