Studying the effects and cause of the massive star formation in Messier 8 East
M. Tiwari, K. M. Menten, F. Wyrowski +4
Messier 8 (M8), one of the brightest HII regions in our Galaxy, is associated with two prominent massive star-forming regions: M8-Main, the particularly bright part of the large sc…
[CII] 158 μm self-absorption and optical depth effects
C. Guevara, J. Stutzki, V. Ossenkopf-Okada +7
Context. The [CII] 158 μm far-infrared (FIR) fine-structure line is one of the most important cooling lines of the star-forming interstellar medium (ISM). High spectral resolution…
Observational study of hydrocarbons in the bright photodissociation region of Messier 8
M. Tiwari, K. M. Menten, F. Wyrowski +3
Hydrocarbons are ubiquitous in the interstellar medium, but their formation is still not well understood, depending on the physical environment they are found in. M8 is host to one…
A thorough view of the nuclear region of NGC 253 - Combined Herschel, SOFIA and APEX dataset
J. P. Pérez-Beaupuits, R. Güsten, A. Harris +5
We present a large set of spectral lines detected in the central region of the starburst galaxy NGC 253. Observations were obtained with the three instruments SPIRE, PACS and…
Unveiling the remarkable photodissociation region of M8
M. Tiwari, K. M. Menten, F. Wyrowski +5
Messier 8 is one of the brightest HII regions in the sky. Using SOFIA, APEX 12 m and IRAM 30 m telescopes, we have performed a comprehensive imaging survey of the emission from the…
Disentangling the excitation conditions of the dense gas in M17 SW
J. P. Pérez-Beaupuits, R. Güsten, M. Spaans +7
We probe the chemical and energetic conditions in dense gas created by radiative feedback through observations of multiple CO, HCN and HCO transitions toward the dense core of…
Outflow forces in intermediate mass star formation
T. A. van Kempen, M. R. Hogerheijde, E. F. van Dishoeck +22
Intermediate mass protostarsprovide a bridge between theories of low- and high-mass star formation. Emerging molecular outflows can be used to determine the influence of fragmentat…
APEX-CHAMP+ high-J CO observations of low-mass young stellar objects: IV. Mechanical and radiative feedback
Umut A. Yıldız, Lars E. Kristensen, Ewine F. van Dishoeck +14
During the embedded stage of star formation, bipolar molecular outflows and UV radiation from the protostar are important feedback processes. Our aim is to quantify the feedback, m…
The nature of the ISM in galaxies during the star-formation activity peak of the Universe
G. Popping, J. P. Pérez-Beaupuits, M. Spaans +2
We combine a semi-analytic model of galaxy formation, tracking atomic and molecular phases of cold gas, with a three-dimensional radiative-transfer and line tracing code to study t…
The deeply obscured AGN of NGC4945 I. Spitzer-IRS maps of [Ne V], [Ne II], H2 0-0 S(1), S(2), and other tracers
J. P. Pérez-Beaupuits, H. W. W. Spoon, M. Spaans +1
The nearly edge-on galaxy NGC4945 is one of the closest galaxies where an AGN and starburst coexist, and is one of the brightest sources at 100 keV. Near and mid-infrared spectrosc…
A Survey of HC3N in Extragalactic Sources - Is HC3N a Tracer of Activity in ULIRGs?
J. E. Lindberg, S. Aalto, F. Costagliola +3
Context. HC3N is a molecule that is mainly associated with Galactic star-forming regions, but it has also been detected in extragalactic environments. Aims. To present the first ex…
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…
HNC, HCN and CN in Seyfert galaxies
J. P. Pérez-Beaupuits, S. Aalto, H. Gerebro
Bright HNC 1--0 emission has been found towards several Seyfert galaxies. This is unexpected since traditionally HNC is a tracer of cold (10 K) gas, and the molecular gas of lumino…
