The Herschel PEP/HerMES luminosity function - I. Probing the evolution of PACS selected Galaxies to z ≃ 4
Berta, S.; Magnelli, B.; Nordon, R. +100 more
We exploit the deep and extended far-IR data sets (at 70, 100 and 160 µm) of the Herschel Guaranteed Time Observation (GTO) PACS Evolutionary Probe (PEP) Survey, in combination with the Herschel Multi-tiered Extragalactic Survey data at 250, 350 and 500 µm, to derive the evolution of the rest-frame 35-, 60-, 90- and total infrared (IR)…
Characterization of SCUBA-2 450 µm and 850 µm selected galaxies in the COSMOS field
Casey, Caitlin M.; Koss, Michael; Capak, Peter +8 more
We present deep 450 µm and 850 µm observations of a large, uniformly covered 394 arcmin2 area in the Cosmic Evolution Survey (COSMOS) field obtained with the SCUBA-2 instrument on the James Clerk Maxwell Telescope (JCMT). We achieve root-mean-square noise values of σ450 = 4.13 mJy and σ850 = 0.80 mJy. T…
The Herschel census of infrared SEDs through cosmic time
Berta, S.; Magnelli, B.; Nordon, R. +57 more
Using Herschel data from the deepest SPIRE and PACS surveys (HerMES and PEP) in COSMOS, GOODS-S and GOODS-N, we examine the dust properties of infrared (IR)-luminous (LIR > 1010 L⊙) galaxies at 0.1 < z < 2 and determine how these evolve with cosmic time. The unique angle of this work is the rigorous analys…
Resolved debris discs around A stars in the Herschel DEBRIS survey
Matthews, Brenda C.; Duchêne, Gaspard; Kalas, Paul +12 more
The majority of debris discs discovered so far have only been detected through infrared excess emission above stellar photospheres. While disc properties can be inferred from unresolved photometry alone under various assumptions for the physical properties of dust grains, there is a degeneracy between disc radius and dust temperature that depends …
Calibration of the total infrared luminosity of nearby galaxies from Spitzer and Herschel bands
Helou, G.; Boquien, M.; Roussel, H. +20 more
When combined with infrared observations with the Spitzer telescope (3 to 160 µm), the Herschel Space Observatory now fully samples the thermal dust emission up to 500 µm and enables us to better estimate the total infrared-submm energy budget (LTIR) of nearby galaxies. We present new empirical calibrations to estimate resol…
Flux calibration of the Herschel★-SPIRE photometer
Valtchanov, I.; Bock, J. J.; Spencer, L. D. +16 more
We describe the procedure used to flux calibrate the three-band submillimetre photometer in the Spectral and Photometric Imaging Receiver instrument on the Herschel Space Observatory. This includes the equations describing the calibration scheme, a justification for using Neptune as the primary calibration source, a description of the observations…
First results from the Herschel Gould Belt Survey in Taurus
Abergel, A.; Bernard, J. -P.; Hill, T. +26 more
The whole of the Taurus region (a total area of 52 deg2) has been observed by the Herschel Spectral and Photometric Imaging Receiver (SPIRE) and Photodetector Array Camera and Spectrometer (PACS) instruments at wavelengths of 70, 160, 250, 350 and 500 µm as part of the Herschel Gould Belt Survey. In this paper we present the first…
Dust and star formation properties of a complete sample of local galaxies drawn from the Planck Early Release Compact Source Catalogue
Baccigalupi, C.; Bonavera, L.; Clements, D. L. +16 more
We combine Planck High Frequency Instrument data at 857, 545, 353 and 217 GHz with data from Wide-field Infrared Survey Explorer (WISE), Spitzer, IRAS and Herschel to investigate the properties of a well-defined, flux-limited sample of local star-forming galaxies. A 545 GHz flux density limit was chosen so that the sample is 80 per cent complete a…
Connecting stellar mass and star-formation rate to dark matter halo mass out to z ∼ 2
Ivison, R. J.; Ilbert, O.; Béthermin, M. +17 more
We have constructed an extended halo model (EHM) which relates the total stellar mass and star-formation rate (SFR) to halo mass (Mh). An empirical relation between the distribution functions of total stellar mass of galaxies and host halo mass, tuned to match the spatial density of galaxies over 0 < z < 2 and the clustering prope…
Formation of the compact jets in the black hole GX 339-4.
Aussel, H.; Tomsick, J. A.; Rodriguez, J. +15 more
Galactic black hole binaries produce powerful outflows which emit over almost the entire electromagnetic spectrum. Here, we report the first detection with the Herschel observatory of a variable far-infrared source associated with the compact jets of the black hole transient GX 339-4 during the decay of its recent 2010-2011 outburst, after the tra…
