GAS II. UV luminosity functions & InfraRed eXcess
Dust is a crucial component of the interstellar medium of galaxies. The presence of dust strongly affects the light produced by stars within a galaxy. As these photons are our... -
X-shooter spectra of 43 metal-poor M dwarfs
The aim of the project is to define metallicity/gravity/temperature scales for different spectral types of metal-poor M dwarfs. We obtained intermediate-resolution ultraviolet... -
Reduced X-shooter spectra of GRB 190114A
We report the detections of molecular hydrogen (H_2_), vibrationally-excited H_2_ (H_2_), and neutral atomic carbon (CI), an efficient tracer of molecular gas, in two new... -
Carbon depletion observed inside T Tauri inner rims
The carbon content of protoplanetary disks is an important parameter to characterize planets formed at different disk radii. There is some evidence from far-infrared and... -
HeI IR triplet measurements for M dwarfs
The HeI infrared (IR) triplet at 10830{AA} is an important activity indicator for the Sun and in solar-type stars, however, it has rarely been studied in relation to M dwarfs to... -
TW Hydrae association with X-shooter
Measurements of the protoplanetary disk frequency in young star clusters of different ages indicate disk lifetimes <10Myr. However, our current knowledge of how mass... -
K band spectrum of beta Pictoris b
Beta Pictoris is arguably one of the most studied stellar systems outside of our own. Some 30 years of observations have revealed a highly-structured circumstellar disk, with... -
M8, G333.6-0.2 and NGC6357 young stars
The identification and characterisation of populations of young massive stars in (giant) HII regions provides important constraints on i) the formation process of massive stars... -
KiDS-VIKING-450 cosmic shear
We present a tomographic cosmic shear analysis of the Kilo-Degree Survey (KiDS) combined with the VISTA Kilo-Degree Infrared Galaxy Survey (VIKING). This is the first time that... -
NIR spectrum of interstellar object 2I/Borisov
Interstellar objects (ISOs) passing through our Solar System offer a rare opportunity to probe the physical and chemical processes involved in solid body and planet formation in... -
M dwarfs HeI infrared triplet variability
The HeI infrared (IR) triplet at 10830{AA} is an important activity indicator for the Sun and in solar-type stars, however, it has rarely been studied in relation to M dwarfs to... -
CS Cha B spectrum
Direct imaging provides a steady flow of newly discovered giant planets and brown dwarf companions. These multi-object systems can provide information about the formation of... -
EX Lup SPHERE and SINFONI images
EX Lup is a well-studied T Tauri star that represents the prototype of young eruptive stars EXors. These are characterized by repetitive outbursts due to enhanced accretion from... -
Five Herbig-Haro objects SOFIA/FIFI-LS images
We present SOFIA/FIFI-LS observations of five prototypical, low-mass Class I outflows (HH111, SVS13, HH26, HH34, HH30) in the far-infrared [OI]63um and [OI]145um transitions.... -
Young visual M-dwarf binaries spectra
We present the results from an integral field spectroscopy study of seven close visual binary pairs of young M-dwarf multiple systems. The target systems are part of the... -
Near-infrared spectra for TW Hya
Volatile molecules are critical to terrestrial planetary habitability, yet they are difficult to observe directly where planets form at the midplanes of protoplanetary disks. It... -
Linking ice and gas. Serpens SVS4
The interaction between dust, ice, and gas during the formation of stars produces complex organic molecules. While observations indicate that several species are formed on... -
Ly{alpha}-[CII] velocity offsets in MS galaxies
The Lyman-{alpha} line in the ultraviolet (UV) and the [CII] line in the far-infrared (FIR) are widely used tools to identify galaxies in the early Universe and to obtain... -
Jurassic structure
Detailed elemental-abundance patterns of giant stars in the Galactic halo measured by the Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have revealed the... -
FU Ori multi-band interferometric observations
FU Orionis is the archetypal FUor star, a subclass of young stellar object (YSO) that undergo rapid brightening events, often gaining 4-6 magnitudes on timescales of days. This...
