We analyse spectroscopic CCD material obtained at the Haute Provence Observatory. We provide line identifications and equivalent width measurements in the wavelength region...

We present a new lens model for the z=0.396 galaxy cluster MACS J0416.1-2403 based on a previously known set of 77 spectroscopically confirmed, multiply imaged galaxies plus an...

High mass-loss rates of red supergiants (RSGs) drastically affect their evolution and final fate, yet their mass-loss mechanism remains poorly understood. Various empirical...

T Pyx is one of the most enigmatic recurrent novae, and it has been proposed as a potential Galactic type-Ia supernova progenitor. Using spatially resolved data obtained with...

While nearly two dozen spiral arms have been detected from planet-forming disks in near-infrared scattered light, none of their substellar drivers has been confirmed. By...

High-resolution spectra in the near-infrared (NIR) are an important tool for the detailed study of stellar atmospheres. The accurate identification of elements and molecules in...

Gas cooling processes in the interstellar medium (ISM) are key to understanding how star formation occurs in galaxies. Far-infrared (FIR) fine-structure emission lines can be...

An edge-on debris disk was detected in 2015 around the young, nearby A0V star HD 110058. The disk showed features resembling those seen in the disk of beta Pictoris that could...

T Tauri stars are low-mass young stars whose disks provide the setting for planet formation, which is one of the most fundamental processes in astronomy. Yet the mechanisms of...

VANDELS is a deep spectroscopic survey, performed with the VIMOS instrument at VLT, aimed at studying in detail the physical properties of high redshift galaxies. VANDELS...

Emission lines indicative of active accretion have been seen on a handful of low-mass companions (M<30MJup) to stars. Line variability is ubiquitous on stellar accretors but...

Cool stars, such as M giants, can only be analyzed in the near-infrared (NIR) regime due to the ubiquitous titanium oxide features in optical spectra of stars with...

We report the discovery of HN Lib b, a sub-Neptunian mass planet orbiting the nearby (d~6.25pc) M4.0 V star HN Lib detected by our CARMENES radial-velocity (RV) survey. We...

Far-infrared line emission provides key information about the gas cooling and heating due to shocks and UV radiation associated with the early stages of sta r formation. Gas...

Stellar feedback in high-redshift galaxies plays an important, if not dominant, role in the re-ionisation epoch of the Universe. Because of their extreme star formation (SF),...

The Euclid mission will conduct an extragalactic survey over 15000deg^2^ of the extragalactic sky. The spectroscopic channel of the Near-Infrared Spectrometer and Photometer...

we aim to characterize the properties of the stellar populations in the central few hundred parsecs of nearby galactic nuclei: age, mass, and 3D geometry. We use spatially...
