Cooling lines as probes of the formation and buildup of galaxies and black holes
P. P. van der Werf, M. Spaans
We discuss the use of SPICA to study the cosmic history of star formation and accretion by supermassive black holes. The cooling lines, in particular the high-J rotational lines of…
CHAMP+ observations of warm gas in M17 SW
J. P. Pérez-Beaupuits, M. Spaans, M. R. Hogerheijde +3
Since the main cooling lines of the gas phase are important tracers of the interstellar medium in Galactic and extragalactic sources, proper and detailed understanding of their emi…
Molecular Gas Disk Structures around AGNs
Keiichi Wada, Padeli Papadopoulos, Marco Spaans
We present new high resolution numerical simulations of the ISM in a central R ~32 parsecs region around a supermassive black hole at a galactic center. Three-dimensional hydrodyna…
Chemical stratification in the Orion Bar: JCMT Spectral Legacy Survey observations
Matthijs H. D. van der Wiel, Floris F. S. van der Tak, Volker Ossenkopf +4
Photon-dominated regions (PDRs) are expected to show a layered structure in molecular abundances and emerging line emission, which is sensitive to the physical structure of the reg…
