Herschel-ATLAS: Extragalactic number counts from 250 to 500 microns*
Aims. The Herschel-ATLAS survey (H-ATLAS) will be the largest area survey to be undertaken by the Herschel Space Observatory. It will cover 550 sq. deg. of extragalactic sky at wavelengths of 100, 160, 250, 350 and 500 μm when completed, reaching flux limits (5σ) from 32 to 145 mJy. We here present galaxy number counts obtained for SPIRE observations of the first ∼14 sq. deg. observed at 250, 3...
متن کاملThe Arecibo Legacy Fast ALFA (ALFALFA) Extragalactic HI Survey
The Arecibo Legacy Fast ALFA (ALFALFA) survey is a program aimed at obtaining a census of HI-bearing objects over a cosmologically significant volume of the local universe. When complete in ∼3–4 years, it will cover 7000 square degrees of high latitude sky using the 305 m telescope and the seven-beam Arecibo L-band feed array (ALFA). As of May 1, 2008, almost 60% of the required observations ar...
متن کاملHELP: XID+, the probabilistic de-blender for Herschel SPIRE maps
We have developed a new prior-based source extraction tool, XID+, to carry out photometry in the Herschel SPIRE (Spectral and Photometric Imaging Receiver) maps at the positions of known sources. XID+ is developed using a probabilistic Bayesian framework that provides a natural framework in which to include prior information, and uses the Bayesian inference tool Stan to obtain the full posterio...
متن کاملAn infrared–radio simulation of the extragalactic sky: from the Square Kilometer Array to Herschel
To exploit synergies between the Herschel Space Observatory and next generation radio facilities, we have extended the semi-empirical extragalactic radio continuum simulation of Wilman et al. to the midand far-infrared. Here we describe the assignment of infrared spectral energy distributions (SEDs) to the star-forming galaxies and active galactic nuclei, using Spitzer 24, 70 and 160μm and SCUB...
متن کاملStudying Galaxy Evolution with Spitzer and Herschel Cup Conference Series, Vol. **volume**, 2006 Extragalactic Science with Herschel-spire
SPIRE, the Spectral and Photometric Imaging Receiver, is one of three instruments to fly on ESA's Herschel Space Observatory. It contains a three-band imaging photometer operating at 250, 360 and 520 µm, and an imaging Fourier Transform Spectrometer (FTS) covering 200-670 µm. It will be used for many extragalactic science programmes, a number of which will be implemented as Herschel Key Project...
