On R-W1 as A Diagnostic to Discover Obscured Active Galactic Nuclei in Wide-Area X-ray Surveys
Stephanie M. LaMassa, Francesca Civano, Marcella Brusa +18
Capitalizing on the all-sky coverage of {\it WISE}, and the 35\% and 50\% sky coverage from SDSS and Pan-STARRS, respectively, we explore the efficacy of (optical) - $m_{3.…
Measures of galaxy dust and gas mass with Herschel photometry and prospects for ALMA
S. Berta, D. Lutz, R. Genzel +2
(Abridged) Combining the deepest Herschel extragalactic surveys (PEP, GOODS-H, HerMES), and Monte Carlo mock catalogs, we explore the robustness of dust mass estimates based on mod…
The XXL Survey X: K-band luminosity - weak-lensing mass relation for groups and clusters of galaxies
F. Ziparo, G. P. Smith, S. L. Mulroy +15
We present the K-band luminosity-halo mass relation, , for a subsample of 20 of the 100 brightest clusters in the XXL Survey observed with WIRCam at the Canad…
How chemistry influences cloud structure, star formation, and the IMF
S. Hocuk, S. Cazaux, M. Spaans +1
In the earliest phases of star-forming clouds, stable molecular species, such as CO, are important coolants in the gas phase. Depletion of these molecules on dust surfaces affects…
Mid-J CO shock tracing observations of infrared dark clouds II Low-J CO constraints on excitation, depletion, and kinematics
A. Pon, D. Johnstone, P. Caselli +6
Infrared dark clouds are kinematically complex molecular structures in the interstellar medium that can host sites of massive star formation. We present 4 square arcminute maps of…
Reconstructing the history of water ice formation from HDO/H2O and D2O/HDO ratios in protostellar cores
K. Furuya, E. F. van Dishoeck, Y. Aikawa
Recent interferometer observations have found that the D2O/HDO abundance ratio is higher than that of HDO/H2O by about one order of magnitude in the vicinity of low-mass protostar…
Gas expulsion in massive star clusters? Constraints from observations of young and gas-free objects
Martin G. H. Krause, Corinne Charbonnel, Nate Bastian +1
Gas expulsion is a central concept in some of the models for multiple populations and the light-element anticorrelations in globular clusters. If the star formation efficiency was…
Stratified NH and ND emission in the prestellar core 16293E in L1689N
A. Bacmann, F. Daniel, P. Caselli +6
High degrees of deuterium fractionation are commonly found in cold prestellar cores and in the envelopes around young protostars. As it brings strong constraints to chemical models…
The Chandra COSMOS Legacy survey: optical/IR identifications
S. Marchesi, F. Civano, M. Elvis +27
We present the catalog of optical and infrared counterparts of the Chandra COSMOS-Legacy Survey, a 4.6 Ms Chandra program on the 2.2 square degrees of the COSMOS field, combination…
Faint COSMOS AGN at z~3.3 - I. Black Hole Properties and Constraints on Early Black Hole Growth
Benny Trakhtenbrot, Francesca Civano, C. Megan Urry +9
We present new Keck/MOSFIRE K-band spectroscopy for a sample of 14 faint, X-ray-selected active galactic nuclei (AGNs) in the COSMOS field. The data cover the spectral region surro…
Clusters of Small Clumps Can Explain The Peculiar Properties of Giant Clumps in High-Redshift Galaxies
Manuel Behrendt, Andreas Burkert, Marc Schartmann
Giant clumps are a characteristic feature of observed high-redshift disk galaxies. We propose that these kpc-sized clumps have a complex substructure and are the result of many sma…
Stellar Mass to Halo Mass Scaling Relation for X-ray Selected Low Mass Galaxy Clusters and Groups out to Redshift
I. Chiu, A. Saro, J. Mohr +6
We present the stellar mass-halo mass scaling relation for 46 X-ray selected low-mass clusters or groups detected in the XMM-BCS survey with masses $2\times10^{13}M_{\odot}\lesssim…
Molecular Gas Velocity Dispersions in the Andromeda Galaxy
Anahi Caldu-Primo, Andreas Schruba
In order to characterize the distribution of molecular gas in spiral galaxies, we study the line profiles of CO:1-0 emission in Andromeda, our nearest massive spiral galaxy. We com…
Rest-UV Absorption Lines as Metallicity Estimator: the Metal Content of Star-Forming Galaxies at z~5
A. L. Faisst, P. L. Capak, I. Davidzon +12
We measure a relation between the depth of four prominent rest-UV absorption complexes and metallicity for local galaxies and verify it up to z~3. We then apply this relation to a…
The 31 Deg Release of the Stripe 82 X-ray Survey: The Point Source Catalog
Stephanie M. LaMassa, C. Megan Urry, Nico Cappelluti +23
We release the next installment of the Stripe 82 X-ray survey point-source catalog, which currently covers 31.3 deg of the Sloan Digital Sky Survey (SDSS) Stripe 82 Legacy fiel…
High-Mass X-ray binaries in the Small Magellanic Cloud
Frank Haberl, Richard Sturm
The last comprehensive catalogue of high-mass X-ray binaries in the Small Magellanic Cloud (SMC) was published about ten years ago. Since then new such systems were discovered, mai…
