Project leader: Simon, Robert (PH1)
Project B2 aims at characterizing the feedback of massive stars and their embedding habitats in the Milky Way and Magellanic Clouds through spectroscopy of atomic and molecular lines. Spectral resolution of the lines is important as it allows us to study in detail the dynamics of the gas. We will contribute data from novel large scale surveys conducted with the Fred Young Submillimeter Telescope (FYST) at the CCAT observatory in Chile starting in 2024. The spectral lines that we will observe with CHAI, the CCAT-prime Heterodyne Array Instrument currently being built in Cologne, are the CO (4-3) and (7-6) rotational lines (tracing the warm, dense gas associated with stellar feedback) and the (1-0) and (2-1) fine structure transitions of neutral atomic carbon [C I] (tracing the atomic phase of Photon Dominated Regions (PDRs) and CO-dark H2). Observations of these lines on scales of many square degrees and at angular resolutions comparable to other large scale surveys (e.g., in the submm and infrared continuum or in spectral lines of CO and HI) are so far missing and therefore an invaluable addition to existing and future data.
The new FYST/CCAT-prime data will be analysed together with the wealth of available comple- mentary data and in the context of other studies in this CRC. An essential part of the analysis and interpretation will involve modelling of PDRs and cloud formation and evolution simulations in collaboration with the relevant CRC sub-projects. Our project concentrates on large scale observations at spatial resolutions between ∽0.1 pc in nearby clouds of the Milky Way and ∽10 pc for the Magellanic Clouds. It will thus provide important information for the small scale studies in the A- projects and, together with the study of nearby galaxies in B3, the large scale view and statistics for the massive stellar habitats in the Milky Way and the closest galaxies. Project B2, therefore, plays an important role in bridging the spatial and environmental gap between the A- and C- projects.
