Context. The Hubble Ultra Deep field (HUDF) is the deepest region ever observed with the Hubble Space Telescope. With the main objective of unveiling the nature...
The MOPYS project: A survey of 70 planets in search of extended He I and H atmospheres: No evidence of enhanced evaporation in young planets
During the first billion years of their life, exoplanet atmospheres are modified by different atmospheric escape phenomena that can strongly affect the shape...
The most recent burst of star formation in the massive elliptical galaxy NGC 1052
High spatial resolution near-infrared (NIR) images of the central 24 × 24 arcsec2 (˜2 × 2 kpc2) of the elliptical galaxy NGC 1052 reveal a total of 25 compact...
The multichord stellar occultation on 2019 October 22 by the trans-Neptunian object (84922) 2003 VS<SUB>2</SUB>
Context. Stellar occultations have become one of the best techniques to gather information about the physical properties of trans-Neptunian objects (TNOs)...
The near-infrared Ca II triplet as a metallicity indicator - II. Extension to extremely metal-poor metallicity regimes
We extend our previous calibration of the infrared Ca II triplet (CaT) as a metallicity indicator to the metal-poor regime by including observations of 55 field...
The non-peculiar velocity dispersion profile of the stellar system ω Centauri
We present the results of a survey of radial velocities over a wide region extending from r ~= 10 out to 80 arcmin (~1.5 tidal radii) within the massive star...
The nuclear dust lane of Circinus: collimation without a torus
In some AGN, nuclear dust lanes connected to kpc-scale dust structures provide all the extinction required to obscure the nucleus, challenging the role of the...
The O3N2 and N2 abundance indicators revisited: improved calibrations based on CALIFA and Te-based literature data
The use of integral field spectroscopy is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies...
