Blind detections of CO J=1-0 IN 11 H-ATLAS Galaxies at z=2.1-3.5 with the GBT/Zpectrometer
(2012-06-20)
We report measurements of the carbon monoxide ground state rotational transition ((CO)-C-12-O-16 J = 1-0) with the Zpectrometer ultrawideband spectrometer on the 100 m diameter Green Bank Telescope. The sample comprises ...
The suppression of star formation by powerful active galactic nuclei
(2012-05)
The old, red stars that constitute the bulges of galaxies, and the massive black holes at their centres, are the relics of a period in cosmic history when galaxies formed stars at remarkable rates and active galactic nuclei ...
Herschel-ATLAS : toward a sample of similar to 1000 strongly lensed galaxies
(2012-04-10)
While the selection of strongly lensed galaxies (SLGs) with 500 mu m flux density S-500 > 100 mJy has proven to be rather straightforward, for many applications it is important to analyze samples larger than the ones ...
Herschel -ATLAS/GAMA : a census of dust in optically selected galaxies from stacking at submillimetre wavelengths
(2012-04)
We use the Herschel-ATLAS survey to conduct the first large-scale statistical study of the submillimetre properties of optically selected galaxies. Using similar to 80 000 r-band selected galaxies from 126 deg2 of the GAMA ...
The Herschel Multi-tiered Extragalactic Survey : SPIRE-mm photometric redshifts
(2012-02-01)
We investigate the potential of submm–mm and submm–mm–radio photometric redshifts using a sample of mm-selected sources as seen at 250, 350 and 500μm by the SPIRE instrument on Herschel. From a sample of 63 previously ...
The environment and characteristics of low-redshift galaxies detected by the Herschel-ATLAS
(2011-11-01)
We investigate the ultraviolet and optical properties and environment of low-redshift galaxies detected in the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) science demonstration data. We use the Sloan Digital ...
Herschel -ATLAS : Rapid evolution of dust in galaxies over the last 5 billion years
(2011-10-01)
We present the first direct and unbiased measurement of the evolution of the dust mass function of galaxies over the past 5 billion years of cosmic history using data from the Science Demonstration Phase of the ...
Modeling of the Hermes submillimeter source lensed by a dark matter dominated foreground group of galaxies
(2011-09-10)
We present the results of a gravitational lensing analysis of the bright z(s) = 2.957 submillimeter galaxy (SMG) HERMES found in the Herschel/SPIRE science demonstration phase data from the Herschel Multi-tiered Extragalactic ...
Herschel-Astrophysical Terahertz Large Area Survey: detection of a far-infrared population around galaxy clusters
(2011-09)
We report the detection of a significant excess in the surface density of far-infrared sources from the Herschel-Astrophysical Terahertz Large Area Survey within similar to 1Mpc of the centres of 66 optically selected ...
Herschel-ATLAS : Counterparts from the ultraviolet-near-infrared in the science demonstration phase catalogue
(2011-09)
We present a technique to identify optical counterparts of 250-mu m-selected sources from the Herschel-ATLAS survey. Of the 6621 250 mu m > 32-mJy sources in our science demonstration catalogue we find that similar to 60 ...
