The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

The James Webb Space Telescope (JWST, Gardner et al. 2006) is a 6.5 m space telescope
launched in 2021 December and is developed by the National Aeronautics and Space …

Aim. We have investigated the gas organization within the paradigmatic Integral Shape
Filament (ISF) in Orion in order to decipher whether or not all filaments are bundles of fibers …

Context. Molecular lines and line ratios are commonly used to infer properties of extra-
galactic star forming regions. The new generation of millimeter receivers almost turns every …

Massive stars inject mechanical and radiative energy into the surrounding environment,
which stirs it up, heats the gas, produces cloud and intercloud phases in the interstellar …

Context. The gas kinetic temperature (TK) determines the physical and chemical evolution of
the interstellar medium (ISM). However, obtaining reliable TK estimates usually requires …

We present an analysis of [] Oi 63,[Oiii] 88,[Nii] 122, and [] Cii 158 far-infrared (FIR) fine-
structure line observations obtained with Herschel/PACS, for∼ 240 local luminous infrared …

Context. The Orion Molecular Cloud is the nearest massive-star forming region. Massive
stars have profound effects on their environment due to their strong radiation fields and …

To improve our understanding of high-z galaxies, we study the impact of H2 chemistry on
their evolution, morphology and observed properties. We compare two zoom-in high …

The SHINING survey offers a great opportunity to study the properties of the ionized and
neutral media of galaxies from prototypical starbursts and active galactic nuclei (AGNs) to …
