We use ASAD2, the new version of ASAD (Analyzer of Spectra for Age Determination), to obtain the age and reddening of 27 Large Magellanic Cloud (LMC) clusters...
AGILE, Fermi, Swift, and GASP/WEBT multi-wavelength observations of the high-redshift blazar 4C +71.07 in outburst
Context. The flat-spectrum radio quasar 4C +71.07 is a high-redshift (z = 2.172), γ-loud blazar whose optical emission is dominated by thermal radiation from...
AGN feedback and star formation in the peculiar galaxy NGC 232: insights from VLT-MUSE observations
We use VLT-MUSE integral field unit data to study the ionized gas physical properties and kinematics as well as the stellar populations of the Seyfert 2 galaxy...
AGN feedback in action in the molecular gas ring of the Seyfert galaxy NGC 7172
We present new ALMA observations of the CO(3−2) transition and associated 854 μm continuum at 0.06 − 0.3″ resolution, together with new VLT/SINFONI observations...
AGN feedback in the Local Universe: Multiphase outflow of the Seyfert galaxy NGC 5506
We present new optical GTC/MEGARA seeing-limited (0.9″) integral-field observations of NGC 5506, together with ALMA observations of the CO(3 − 2) transition at...
AGN-host galaxy connection: morphology and colours of X-ray selected AGN at z ≤ 2
Context. The connection between active galactic nuclei (AGN) and their host galaxies has been widely studied and found to be of great importance for providing...
We present the most complete atlas of nuclear rings to date. We include 113 rings found in 107 galaxies, six of which are elliptical galaxies, five are highly...
Albedo and atmospheric constraints of dwarf planet Makemake from a stellar occultation
Pluto and Eris are icy dwarf planets with nearly identical sizes, comparable densities and similar surface compositions as revealed by spectroscopic studies...
In order to test the expansion of the universe and its geometry, we carry out an Alcock-Paczyński cosmological test, that is, an evaluation of the ratio of...
