GaAs-chip-based mid-infrared supercontinuum generation
The mid-infrared spectral region opens up new possibilities for applications such as molecular spectroscopy with high spatial and frequency...

Magnetic origin of the discrepancy between stellar limb-darkening models and observations
Stars appear darker at their limbs than at their disk centres because at the limb we are viewing the higher and cooler layers of stellar...

Ultradeep Near-Infrared ISAAC Observations of the Hubble Deep Field South: Selecting High-Redshift Galaxies in the Rest-Frame Optical
We present very deep near-infrared imaging of the Hubble Deep Field South with ISAAC on the Very Large Telescope. We obtained more than 100 hours...

A mature quasar at cosmic dawn revealed by JWST rest-frame infrared spectroscopy
The rapid assembly of the first supermassive black holes is an enduring mystery. Until now, it was not known whether quasar ‘feeding’ structures (the...

Observations of planet forming disks in multiple stellar systems
The demographic of circumstellar disks, the birthplaces of planets, is diverse and rich in disks featuring rings, gaps, spirals, filaments, and arcs....

Stellar Mass of Faint Mid-Infrared Galaxies
Near-infrared emission is a good estimator of stellar masses of galaxies. For galaxies at high redshifts, mid-infrared observations are needed to...

Late-Type Stars Seen at High Spectral Resolution at Mid-Infrared Wavelengths
At the end of their lifetime asymptotic giant branch (AGB) stars and red super giants expel large amounts of material into space. This material forms...
