Cosmic-ray Induced Sputtering Of Interstellar Formaldehyde Ices
H2CO is a ubiquitous molecule in the ISM and in the gas phase of prestellar cores, and is likely present in ice mantles, but its main desorption mechanism is unknown. […]

Ices On Pebbles In Protoplanetary Discs
The formation of solid macroscopic grains (pebbles) in protoplanetary discs is the first step toward planet formation. We aim to study the distribution of pebbles and the chemical composition of […]

PHANGS-JWST First Results: Variations in PAH Fraction as a Function of ISM Phase and Metallicity
We present maps tracing the fraction of dust in the form of polycyclic aromatic hydrocarbons (PAHs) in IC 5332, NGC 628, NGC 1365, and NGC 7496 from JWST/MIRI observations.
