The SEDIGISM survey: first data release and overview of the Galactic structure
F. Schuller, J. S. Urquhart, T. Csengeri +57
The SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium) survey used the APEX telescope to map 84 deg^2 of the Galactic plane between l = -60 deg…
The SEDIGISM survey: Molecular clouds in the inner Galaxy
A. Duarte-Cabral, D. Colombo, J. S. Urquhart +57
We use the 13CO(2-1) emission from the SEDIGISM high-resolution spectral-line survey of the inner Galaxy, to extract the molecular cloud population with a large dynamic range in sp…
ATLASGAL-selected massive clumps in the inner Galaxy: VIII. Chemistry of photodissociation regions
W. -J. Kim, F. Wyrowski, J. S. Urquhart +4
We study ten molecular transitions obtained from an unbiased 3 mm molecular line survey using the IRAM 30 m telescope toward 409 compact dust clumps identified by the APEX Telescop…
The warm and dense Galaxy - tracing the formation of dense cloud structures out to the Galactic Center
Thomas Stanke, Henrik Beuther, Jens Kauffmann +11
The past two decades have seen extensive surveys of the far-infrared to submillimeter continuum emission in the plane of our Galaxy. We line out prospects for the coming decade for…
HIFI Spectroscopy of submm Lines in Nuclei of Actively Star Forming Galaxies
L. Liu, A. Weiss, J. P. Perez-Beaupuits +10
We present a systematic survey of multiple velocity-resolved HO spectra using Herschel/HIFI towards nine nearby actively star forming galaxies. The ground-state and low-excitat…
SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium
F. Schuller, T. Csengeri, J. S. Urquhart +41
The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. We have carried out…
Detection of a large fraction of atomic gas not associated with star-forming material in M17 SW
J. P. Perez-Beaupuits, J. Stutzki, V. Ossenkopf +3
We probe the column densities and masses traced by the ionized and neutral atomic carbon with spectrally resolved maps, and compare them to the diffuse and dense molecular gas trac…
The ionized and hot gas in M17 SW: SOFIA/GREAT THz observations of [C II] and 12CO J=13-12
J. P. Perez-Beaupuits, H. Wiesemeyer, V. Ossenkopf +5
With new THz maps that cover an area of ~3.3x2.1 pc^2 we probe the spatial distribution and association of the ionized, neutral and molecular gas components in the M17 SW nebula. W…
The Structure and Dynamics of an AGN Torus: CO Line Predictions for ALMA from 3D Hydrodynamical Simulations with X-ray Driven Chemistry
Juan-Pablo Perez-Beaupuits, Keiichi Wada, Marco Spaans
Many efforts have been made to model the mass distribution and dynamical evolution of the circumnuclear gas in active galactic nuclei (AGNs). However, chemical evolution is not inc…
