We investigate encounters between giant molecular clouds (GMCs) and star clusters. We propose a single expression for the energy gain of a cluster due to an encounter with a GMC, valid for all encounter distances and GMC properties. This relation is verified with N -body simulations of cluster-GMC encounters, where the GMC is represented by a moving analytical potential. Excellent agreement is ...
Formation of secondary atmospheric aerosol particles starts with gas phase molecules forming small molecular clusters. High-resolution mass spectrometry enables the detection and chemical characterization of electrically charged clusters from the molecular scale upward, whereas the experimental detection of electrically neutral clusters, especially as a chemical composition measurement, down to...
TEM pictures that were taken at different polymerization times during the formation process of the intramolecularly cross-linked macromolecule (ICM) indicate that ICM growth undergoes three stages. At the first stage, monomers (i.e. prepolymers) react with each other to form small coils, called “dot molecules” (DM), which are shown as small black dots in TEM pictures. At the second phase, the r...
Subarcsecond infrared and radio observations yield important information about the formation of super star clusters from their surrounding gas. We discuss the general properties of ionized and molecular gas near young, forming SSCs, as illustrated by the prototypical young, forming super star cluster nebula in the dwarf galaxy NGC 5253. This super star cluster appears to have a gravitationally ...
