GOODS-Herschel: Separating High Redshift active galactic Nuclei and star forming galaxies Using Infrared Color Diagnostics
Allison Kirkpatrick, Alexandra Pope, Vassilis Charmandaris +17
We have compiled a large sample of 151 high redshift (z=0.5-4) galaxies selected at 24 microns (S24>100 uJy) in the GOODS-N and ECDFS fields for which we have deep Spitzer IRS spec…
Dust temperature and CO-to-H2 conversion factor variations in the SFR-M* plane
B. Magnelli, A. Saintonge, D. Lutz +15
Deep Herschel imaging and 12CO(2-1) line luminosities from the IRAM PdBI are combined for a sample of 17 galaxies at z>1 from the GOODS-N field. The sample includes galaxies both o…
The Evolving Interstellar Medium of Star Forming Galaxies Since z=2 as Probed by Their Infrared Spectral Energy Distributions
Georgios E. Magdis, E. Daddi, M. Bethermin +11
Using data from the mid-infrared to millimeter wavelengths for individual galaxies and for stacked ensembles at 0.5<z<2, we derive robust estimates of dust masses (Mdust) for main…
An ALMA survey of submillimetre galaxies in the Extended Chandra Deep Field South: High resolution 870um source counts
Alexander Karim, Mark Swinbank, Jackie Hodge +20
We report the first counts of faint submillimetre galaxies (SMG) in the 870-um band derived from arcsecond resolution observations with the Atacama Large Millimeter Array (ALMA). W…
GOODS-Herschel: Impact of Active Galactic Nuclei and Star Formation Activity on Infrared Spectral Energy Distributions at High Redshift
Allison Kirkpatrick, Alexandra Pope, David M. Alexander +25
We explore the effects of active galactic nuclei (AGN) and star formation activity on the infrared (0.3-1000 microns) spectral energy distributions of luminous infrared galaxies fr…
Evidence for a wide range of UV obscuration in z ~ 2 dusty galaxies from the GOODS-Herschel survey
Kyle Penner, Mark Dickinson, Alexandra Pope +20
Dusty galaxies at z ~ 2 span a wide range of relative brightness between rest-frame mid-infrared (8um) and ultraviolet wavelengths. We attempt to determine the physical mechanism r…
The Molecular Gas Content of z = 3 Lyman Break Galaxies; Evidence of a non Evolving Gas Fraction in Main Sequence Galaxies at z > 2
G. E. Magdis, E. Daddi, M. Sargent +10
We present observations of the CO[3-2] emission towards two massive and infrared luminous Lyman Break Galaxies at z = 3.21 and z = 2.92, using the IRAM Plateau de Bure Interferomet…
An ALMA survey of Sub-millimetre Galaxies in the Extended Chandra Deep Field South: Detection of [C II] at z=4.4
Mark Swinbank, Alexander Karim, Ian Smail +19
We present ALMA 870-um (345GHz) observations of two sub-millimetre galaxies (SMGs) drawn from an ALMA study of the 126 sub-millimeter sources from the LABOCA Extended Chandra Deep…
No clear submillimetre signature of suppressed star formation amongst X-ray luminous AGNs
C. M. Harrison, D. M. Alexander, J. R. Mullaney +18
Many theoretical models require powerful active galactic nuclei (AGNs) to suppress star formation in distant galaxies and reproduce the observed properties of today's massive galax…
Herschel-PACS observations of [OI]63um towards submillimetre galaxies at z~1
Kristen Coppin, Alice Danielson, James E. Geach +22
We present Herschel-PACS spectroscopy of the [OI]63um far-infrared cooling line from a sample of six unlensed and spectroscopically-confirmed 870um-selected submillimetre (submm) g…
GOODS-Herschel: Ultra-deep XMM-Newton observations reveal AGN/star-formation connection
E. Rovilos, A. Comastri, R. Gilli +30
Models of galaxy evolution assume some connection between the AGN and star formation activity in galaxies. We use the multi-wavelength information of the CDFS to assess this issue.…

We present high-spatial resolution imaging obtained with the Submillimeter Array (SMA) at 880um and the Keck Adaptive Optics (AO) system at Ks-band of a gravitationally lensed sub-…

Fabian Walter, R. Decarli, C. Carilli +24
The Hubble Deep Field (HDF) is a region in the sky that provides one of the deepest multi-wavelength views of the distant universe and has led to the detection of thousands of gala…
