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…
Herschel/HIFI observations of spectrally resolved methylidyne signatures toward the high-mass star-forming core NGC6334I
M. H. D. van der Wiel, F. F. S. van der Tak, D. C. Lis +65
In contrast to extensively studied dense star-forming cores, little is known about diffuse gas surrounding star-forming regions. We study molecular gas in the high-mass star-formin…
Silicate emissions in active galaxies - From LINERs to QSOs
E. Sturm, M. Schweitzer, D. Lutz +12
We report the first detection of ~10 and ~18 micron silicate dust emissions in a low-luminosity active galactic nucleus (AGN), obtained in Spitzer-IRS 7-37 micron spectroscopy of t…
Black hole accretion and star formation as drivers of gas excitation and chemistry in Mrk231
P. P. Van der Werf, K. G. Isaak, R. Meijerink +34
We present a full high resolution SPIRE FTS spectrum of the nearby ultraluminous infrared galaxy Mrk231. In total 25 lines are detected, including CO J=5-4 through J=13-12, 7 rotat…
Warm Molecular Gas in Luminous Infrared Galaxies
N. Lu, Y. Zhao, C. K. Xu +18
We present our initial results on the CO rotational spectral line energy distribution (SLED) of the to 1 transitions from up to from Herschel SPIRE spectroscop…
Ortho-to-para ratio of interstellar heavy water
C. Vastel, C. Ceccarelli, E. Caux +65
Despite the low elemental deuterium abundance in the Galaxy, enhanced molecular D/H ratios have been found in the environments of low-mass star forming regions, and in particular t…
