The water abundance behind interstellar shocks: results from /PACS and /IRS observations of HO, CO, and H
David A. Neufeld, Antoine Gusdorf, Rolf Güsten +7
We have investigated the water abundance in shock-heated molecular gas, making use of measurements of far-infrared CO and HO line emissions in combination with $Spit…
Rotationally-supported disks around Class I sources in Taurus: disk formation constraints
Daniel Harsono, Jes K. Jorgensen, Ewine F. van Dishoeck +4
(Abridged) Disks are observed around pre-main sequence stars, but how and when they form is still heavily debated. While disks around young stellar objects have been identified thr…
The Black Hole Mass and the Stellar Ring in NGC 3706
Kayhan Gültekin, Karl Gebhardt, John Kormendy +4
We determine the mass of the nuclear black hole () in NGC 3706, an early type galaxy with a central surface brightness minimum arising from an apparent stellar ring, which is mi…
Interstellar water chemistry: from laboratory to observations
Ewine F. van Dishoeck, Eric Herbst, David A. Neufeld
Water is observed throughout the universe, from diffuse interstellar clouds to protoplanetary disks around young stars, and from comets in our own solar system and exoplanetary atm…
The dusty torus in the Circinus galaxy: a dense disk and the torus funnel
K. R. W. Tristram, L. Burtscher, W. Jaffe +5
(Abridged) With infrared interferometry it is possible to resolve the nuclear dust distributions that are commonly associated with the dusty torus in active galactic nuclei (AGN).…
Star Formation and Environmental Quenching of GEEC2 Group Galaxies at z~1
Angus Mok, Michael L. Balogh, Sean L. McGee +7
We present new analysis from the GEEC2 spectroscopic survey of galaxy groups at . Our previous work revealed an intermediate population between the star-forming and quiesc…
Observations of the gas cloud G2 in the Galactic Center
Stefan Gillessen, Reinhard Genzel, Tobias K. Fritz +6
In 2011, we discovered a compact gas cloud ("G2") with roughly three Earth masses that is falling on a near-radial orbit toward the massive black hole in the Galactic Center. The o…
Gas-to-Dust mass ratios in local galaxies over a 2 dex metallicity range
A. Rémy-Ruyer, S. C. Madden, F. Galliano +17
This paper analyses the behaviour of the gas-to-dust mass ratio (G/D) of local Universe galaxies over a large metallicity range. We combine three samples: the Dwarf Galaxy Survey,…
The dependency of AGN infrared color-selection on source luminosity and obscuration: An observational perspective in CDFS and COSMOS
Hugo Messias, Jose M. Afonso, Mara Salvato +2
AIMS. This work addresses the AGN IR-selection dependency on intrinsic source luminosity and obscuration, in order to identify and charaterise biases which could affect conclusions…
Star formation in the cluster CLG0218.3-0510 at z=1.62 and its large-scale environment: the infrared perspective
Joana S. Santos, Bruno Altieri, Masayuki Tanaka +7
The galaxy cluster CLG0218.3-0510 at z=1.62 is one of the most distant galaxy clusters known, with a rich muti-wavelength data set that confirms a mature galaxy population already…
The Mystery of the -Bump -- A new Signature for Major Mergers in Early-type Galaxies?
Anna T. P. Schauer, Rhea-Silvia Remus, Andreas Burkert +1
The stellar velocity dispersion as a function of the galactocentric radius of an early-type galaxy can generally be well approximated by a power law . However, some o…
A Magnified View of the Kinematics and Morphology of RCSGA 032727-132609: Zooming in on a Merger at z=1.7
Eva Wuyts, Jane R. Rigby, Michael D. Gladders +1
We present a detailed analysis of multi-wavelength HST/WFC3 imaging and Keck/OSIRIS near-IR AO-assisted integral field spectroscopy for a highly magnified lensed galaxy at z=1.70.…
Molecular gas in the centre of nearby galaxies from VLT/SINFONI integral field spectroscopy - II. Kinematics
X. Mazzalay, W. Maciejewski, P. Erwin +6
We present an analysis of the H2 emission-line gas kinematics in the inner < 4 arcsec radius of six nearby spiral galaxies, based on AO-assisted integral-field observations obtaine…
Ray-tracing in pseudo-complex General Relativity
T. Schönenbach, G. Caspar, P. O. Hess +4
Motivated by possible observations of the black hole candidate in the center of our galaxy and the galaxy M87, ray-tracing methods are applied to both standard General Relativity (…
Hydrodynamical simulations of a compact source scenario for G2
A. Ballone, M. Schartmann, A. Burkert +6
The origin of the dense gas cloud G2 discovered in the Galactic Center (Gillessen et al. 2012) is still a debated puzzle. G2 might be a diffuse cloud or the result of an outflow fr…
The Nuclear Cluster of the Milky Way: Total Mass and Luminosity
Tobias K. Fritz, Sotiris Chatzopoulos, Ortwin Gerhard +6
Here we present the fundamental properties of the nuclear cluster of the Milky Way. First, we derive its structural properties by constructing a density map of the central 1000'' u…
AGN feedback at z~2 and the mutual evolution of active and inactive galaxies

The relationships between galaxies of intermediate stellar mass and moderate luminosity active galactic nuclei (AGNs) at 1<z<3 are investigated with the Galaxy Mass Assembly ultra-…
Stochastic angular momentum slews and flips and their effect on discs in galaxy formation models
Nelson Padilla, Salvador Salazar-Albornoz, Sergio Contreras +2
The angular momentum of galactic discs in semi-analytic models of galaxy formation is usually updated in time as material is accreted to the disc by adopting a constant dimensionle…
