The Herschel-SPIRE instrument and its in-flight performance
The Spectral and Photometric Imaging REceiver (SPIRE), is the Herschel Space Observatory`s submillimetre camera and spectrometer. It contains a three-band imaging photometer operating at 250, 350 and
High molecular gas fractions in normal massive star-forming galaxies in the young Universe
A survey of molecular gas in samples of typical massive-star-forming galaxies at mean redshifts of about 1.2 and 2.3 reveals that distant star forming galaxies were indeed gas rich, and that the star formation efficiency is not strongly dependent on cosmic epoch.
Initial highlights from the Herschel Gould Belt survey
We summarize the first results from the Gould Belt survey, obtained toward the Aquila Rift and Polaris Flare regions during the 'science demonstration phase' of Herschel. Our 70-500 micron images
An interferometric CO survey of luminous submillimetre galaxies
In this paper, we present results from an Institut de Radio Astronomie Millimetrique (IRAM) Plateau de Bure millimetre-wave Interferometer (PdBI) survey for carbon monoxide (CO) emission towards
350 μm dust emission from high-redshift quasars
We report detections of six high-redshift (1.8 ≤ z ≤ 6.4), optically luminous, radio-quiet quasars at 350 μm, using the SHARC II bolometer camera at the Caltech Submillimeter Observatory. Our
High-resolution millimeter imaging of submillimeter galaxies
We present ~06 resolution IRAM PdBI interferometry of eight submillimeter galaxies at z ~ 2-3.4, where we detect continuum at 1 mm and/or CO lines at 3 and 1 mm. The CO 3-2/4-3 line profiles in five
A dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
Despite the overall downturn in cosmic star formation towards the highest redshifts, it seems that environments mature enough to form the most massive, intense starbursts existed at least as early as 880 million years after the Big Bang.
A survey of molecular gas in luminous sub-millimetre galaxies
We present the results from a survey of 12CO emission in 40 luminous sub-millimetre galaxies (SMGs), with 850-μm fluxes of S850 μm = 4–20 mJy, conducted with the Plateau de Bure Interferometer. We
Intense star formation within resolved compact regions in a galaxy at z = 2.3
Observations of the sub-millimetre galaxy SMMJ2135-0102, which has been gravitationally magnified by a factor of 32 by a massive foreground galaxy cluster lens, find that the luminosity densities of these star-forming regions are comparable to the dense cores of giant molecular clouds in the local Universe, but they are about a hundred times larger and 107 times more luminous.
Dust emission from the most distant quasars
We report observations of three SDSS z>6 QSOs at 250 GHz (1.2mm) using the 117-channel Max-Planck Millimeter Bolometer (MAMBO-2) array at the IRAM 30-meter telescope. J1148+5251 (z=6.41) and
