Periodic Reporting for period 3 - CSF (From Cloud to Star Formation)
Reporting period: 2018-09-01 to 2020-02-29
The project is observationally driven and based on two PI-led large observing programs at two of the most advanced radio and mm interferometers, the Very Large Array (VLA), and the Northern Extended Millimeter Array (NOEMA, formerly known as Plateau der Bute Interferometer, PdBI). The THOR program at the VLA investigates the cloud formation and conversion of atomic to molecular gas, as well as feedback processes back to the interstellar medium (ISM). To reach these goals, THOR observes the Milky Way in atomic HI, molecular OH, and cm continuum and radio recombination lines tracing the ionized components of the ISM. At smaller spatial scales, the CORE conduceted with NOEMA studies the fragmentation of the gas clumps to form clusters, the formation of accretion disks and outflows, and the gas infall rates as proxy for the accretion rates. Assisted by Atacama Large Millimeter Array (ALMA) observations, we are investigating a sample of high-mass star-forming regions at the highest spatial resolution of (<=0.2’’) to dissect the physical processes during the assembly of the highest mass stars.
Most of the ERC money is used for postdocs and Phd students to scientifically work on the data. Three postdocs and one PhD have been hired in that framework (one additional PhD student was already working beforehand on the project. His salary is not funded by this project). In addition to this, we acquired computing resources to efficiently reduce the data and analyze the results.
