Gas morphology and energetics at the surface of PDRs: new insights with Herschel observations of NGC 7023
C. Joblin, P. Pilleri, J. Montillaud +37
We investigate the physics and chemistry of the gas and dust in dense photon-dominated regions (PDRs), along with their dependence on the illuminating UV field. Using Herschel-HIFI…
The origin of the [C II] emission in the S140 PDRs - new insights from HIFI
C. Dedes, M. Röllig, B. Mookerjea +38
Using Herschel's HIFI instrument we have observed [C II] along a cut through S140 and high-J transitions of CO and HCO+ at two positions on the cut, corresponding to the externally…
HIFI spectroscopy of low-level water transitions in M82
A. Weiss, M. A. Requena-Torres, R. Guesten +23
We present observations of the rotational ortho-water ground transition, the two lowest para-water transitions, and the ground transition of ionised ortho-water in the archetypal s…
HIFI observations of warm gas in DR21: Shock versus radiative heating
V. Ossenkopf, M. Röllig, R. Simon +35
The molecular gas in the DR21 massive star formation region is known to be affected by the strong UV field from the central star cluster and by a fast outflow creating a bright sho…
