Gas lines from the 5-Myr old optically thin disk around HD141569A. Herschel observations and modeling
Wing-Fai Thi, Christophe Pinte, Eric Pantin +20
At the distance of 99-116 pc, HD141569A is one of the nearest HerbigAe stars that is surrounded by a tenuous disk, probably in transition between a massive primordial disk and a de…
The SCUBA-2 Cosmology Legacy Survey: demographics of the 450 μm-population
I. G. Roseboom, J. S. Dunlop, M. Cirasuolo +47
We investigate the multi-wavelength properties of a sample of 450-μm selected sources from the SCUBA-2 Cosmology Legacy Survey (S2CLS). A total of 69 sources were identified above…
Uncertainties in water chemistry in disks: An application to TW Hya
I. Kamp, W. -F. Thi, G. Meeus +7
Context. This paper discusses the sensitivity of water lines to chemical processes and radiative transfer for the protoplanetary disk around TW Hya. The study focuses on the Hersch…
Using [CI] to probe the Interstellar Medium in z~2.5 Sub-Millimeter Galaxies
S. Alaghband-Zadeh, S. C. Chapman, A. M. Swinbank +7
We present new [CI](1-0) and 12CO(4-3) Plateau de Bure Interferometer observations of five Sub-Millimeter Galaxies (SMGs) and combine these with all available [CI](1-0) literature…
Explaining the [CII]158um Deficit in Luminous Infrared Galaxies - First Results from a Herschel/PACS Study of the GOALS Sample
T. Diaz-Santos, L. Armus, V. Charmandaris +26
We present the first results of a survey of the [CII]158um emission line in 241 luminous infrared galaxies (LIRGs) comprising the Great Observatories All-sky Survey (GOALS) sample,…
Tracing the Physical Conditions in Active Galactic Nuclei with Time-Dependent Chemistry
Rowin Meijerink, Marco Spaans, Inga Kamp +3
We present an extension of the code ProDiMo that allows for a modeling of processes pertinent to active galactic nuclei and to an ambient chemistry that is time dependent. We prese…
The Response of Metal Rich Gas to X-Ray Irradiation from a Massive Black Hole at High Redshift: Proof of Concept
A. Aykutalp, J. H. Wise, R. Meijerink +1
Observational studies show that there is a strong link between the formation and evolution of galaxies and the growth of supermassive black holes (SMBH) at their centers. However,…
Water vapor in the protoplanetary disk of DG Tau
L. Podio, I. Kamp, C. Codella +13
Water is key in the evolution of protoplanetary disks and the formation of comets and icy/water planets. While high excitation water lines originating in the hot inner disk have be…
