Metallicities, Age-Metallicity Relationships, and Kinematics of Red Giant Branch Stars in the Outer Disk of the Large Magellanic Cloud
The outer disk of the Large Magellanic Cloud (LMC) is studied in order to unveil clues about its formation and evolution. We have obtained deep color-magnitude...
MUSE-AO view of the starburst-AGN connection: NGC 7130
We present the discovery of a small 0.2'' (60 pc) radius kinematically decoupled core, as well as an outflow jet, in the archetypical AGN-starburst "composite"...
New insight into the T-type planetary mass population in the Sigma Orionis cluster
The proper characterization of the least massive population of the young Sigma Orionis star cluster is required to understand the form of the cluster mass...
We test the theoretical prediction that the straightest dust lanes in bars are found in strongly barred galaxies, or more specifically, that the degree of...
On the probable existence of an abrupt magnetization in the upper chromosphere of the quiet Sun
We report on a detailed radiative transfer modeling of the observed scattering polarization in the H-alpha line, which allows us to infer quantitative...
Probing gamma-ray production in relativistic jets of flat spectrum radio quasars
The MAGIC telescopes discovered very high energy (VHE, E>100 GeV) gamma-ray emission coming from the distant Flat Spectrum Radio Quasar (FSRQ) PKS 1222+21 (4C...
Relationship between Hubble type and spectroscopic class in local galaxies
We compare the Hubble type and the spectroscopic class of the galaxies with spectra in SDSS/DR7. As it is long known, elliptical galaxies tend to be red whereas...
Rubidium-rich asymptotic giant branch stars in the Magellanic Clouds
Asymptotic Giant Branch (AGB) stars are a principal source of gas and dust input into the interstellar medium, being an important driver of chemical evolution...
