Coronal lines are forbidden emission lines with a ionisation potential χ ≳ 100 eV. They are linked to energetic phenomena triggered by active galactic nuclei...

We present spatially resolved dust-continuum ALMA observations from rest frame ∼60 to ∼600 μm (bands 3–10) of the hyperluminous hot dust-obscured galaxy (hot...

Aims: We report the results of a novel determination of the solar oxygen abundance using spatially resolved observations and inversions. We seek to derive the...

Aims: IRAS 19410+2336 is a young massive star forming region with an intense outflow activity. Outflows are frequently studied in the near-infrared (NIR) since...

Aims: Optical integral-field spectroscopy was used to investigate the planetary nebula NGC 3242. We analysed the main morphological components of this source...

We derive effective temperatures, luminosities and related parameters for a sample of eight Wolf-Rayet stars - seven WN stars and a WO star - by computing...

Context. The relative abundance of the dust grain types in the interstellar medium is directly linked to physical quantities that trace the evolution of...

Gamma-ray bursts (GRBs) have been proposed as a tool for studying star formation in the Universe, so it is crucial to investigate whether their host galaxies...

We present the first automated fitting method for the quantitative spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE...
