Infrared Molecular Starburst Fingerprints in Deeply Obscured (U)LIRG Nuclei
F. Lahuis, H. W. W. Spoon, A. G. G. M. Tielens +6
High resolution spectra of the Spitzer Space Telescope show vibration-rotation absorption bands of gaseous C2H2, HCN, and CO2 molecules toward a sample of deeply obscured (U)LIRG n…
Relativistic Beaming and the Intrinsic Properties of Extragalactic Radio Jets
M. H. Cohen, M. L. Lister, D. C. Homan +4
Relations between the observed quantities for a beamed radio jet, apparent transverse speed and apparent luminosity (beta_app,L), and the intrinsic quantities, Lorentz factor and i…
Tracing high energy radiation with molecular lines near deeply embedded protostars
P. Stauber, A. O. Benz, J. K. Jorgensen +3
Submillimeter lines of CN, NO, CO+ and SO+, and upper limits on SH+ and N2O are observed with the James Clerk Maxwell Telescope in two high-mass and up to nine low-mass young stell…
Astrochemical confirmation of the rapid evolution of massive YSOs and explanation for the inferred ages of hot cores
S. D. Doty, E. F. van Dishoeck, J. C. Tan
Aims. To understand the roles of infall and protostellar evolution on the envelopes of massive young stellar objects (YSOs). Methods. The chemical evolution of gas and dust is trac…
Intrinsic Brightness Temperatures of AGN Jets
D. C. Homan, Y. Y. Kovalev, M. L. Lister +6
We present a new method for studying the intrinsic brightness temperatures of the parsec-scale jet cores of Active Galactic Nuclei (AGN). Our method uses observed superluminal moti…
Water destruction by X-rays in young stellar objects
P. Stauber, J. K. Jorgensen, E. F. van Dishoeck +2
We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemi…
