Water Vapor in the Inner 25 AU of a Young Disk around a Low-Mass Protostar
, 2010 Water is one of the key molecules in the physical and chemical evolution of star- and planet-forming regions. We here report the first spatially resolved observation of thermal emission of (an isotopologue of) water with the Plateau de Bure ...

Fire from Ice - Massive Star Birth from Infrared Dark Clouds
, 2017 I review massive star formation in our Galaxy, focusing on initial conditions in Infrared Dark Clouds (IRDCs), including the search for massive pre-stellar cores (PSCs), and modeling of later stages of massive protostars, i.e., hot molecular cores (HMCs).

Nature's Starships II: Simulating the Synthesis of Amino Acids in Meteorite Parent Bodies
, 2015 Carbonaceous chondrite meteorites are known for having high water and organic material contents, including amino acids. Here we address the origin of amino acids in the warm interiors of their parent bodies (planetesimals) within a few million years of ...

Laboratory Photo-chemistry of PAHs: Ionization versus Fragmentation [PDF]
, 2015 Interstellar polycyclic aromatic hydrocarbons (PAHs) are expected to be strongly processed by vacuum ultraviolet photons. Here, we report experimental studies on the ionization and fragmentation of coronene (C24H12), ovalene (C32H14) and hexa-peri ...

Atlas of Cosmic-Ray-induced Astrochemistry [PDF]
The Astrophysical Journal, 2018 Abstract Cosmic rays are the primary initiators of interstellar chemistry, and getting a better understanding of the varying impact they have on the chemistry of interstellar clouds throughout the Milky Way will not only expand our understanding of interstellar medium chemistry in our own galaxy, but also aid in extra-galactic studies ...

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...
