We summarize the history, concept, scientific program, and technical performance of the
James Webb Space Telescope (JWST, Webb; Gardner et al. 2006). This paper points to and …

The chemistry of the interstellar medium occurs under extreme conditions and can lead to
the formation of exotic molecules. These are species that on Earth are unstable and/or …

Astrochemistry is the science that studies the chemistry in the Universe, namely the
combination of two fields: astronomy and chemistry. It started about fifty years ago and it has …

Context. Many molecules observed in the interstellar medium are thought to result from the
thermal desorption of ices. Parameters such as the desorption energy and pre-exponential …

Reactions in interstellar ices are shown to be capable of producing key prebiotic molecules
without energetic radiation that are necessary for the origins of life. When present in …

Sulfur is one of six life-essential elements, but its path from interstellar clouds to planets and
their atmospheres is not well known. Astronomical observations in dense clouds have so far …

Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase
and thought to be mostly formed on icy grains. Nevertheless, there have not been any …

Context. Understanding the earliest stages of star formation, and setting it in the context of
the general cycle of matter in the interstellar medium, is a central aspect of research with the …

The carbon (3 P) atom is a reactive species that, according to laboratory experiments and
theoretical calculations, condensates with interstellar ice components. This fact is of …

We present an ACA search for [C i] 1–0 emission at 492 GHz toward large T Tauri disks (gas
radii≳ 200 au) in the∼ 1–3 Myr-old Lupus star-forming region. Combined with Atacama …
