The European Large-Area ISO Survey (ELAIS): the final band-merged catalogue
Elbaz, D.; Genzel, R.; Pozzi, F. +76 more
We present the final band-merged European Large-Area ISO Survey (ELAIS) Catalogue at 6.7, 15, 90 and 175 µm, and the associated data at U, g', r', i', Z, J, H, K and 20 cm. The origin of the survey, infrared and radio observations, data-reduction and optical identifications are briefly reviewed, and a summary of the area covered and the comp…
Far-infrared and submillimetre observations of the Crab nebula
Tuffs, R. J.; Popescu, C. C.; Green, D. A.
We present far-infrared (FIR) and submillimetre images of the Crab nebula, taken with the ISOPHOT instrument onboard the Infrared Space Observatory (ISO) and with the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope. The ISOPHOT observations were made in the bands centred at 60, 100 and 170 µm, with FWHM…
Chemical abundances of planetary nebulae from optical recombination lines - I. Observations and plasma diagnostics
Liu, Y.; Barlow, M. J.; Liu, X. -W. +1 more
We have obtained deep optical spectra of medium resolution for a sample of 12 Galactic planetary nebulae (PNe). Optical recombination lines (ORLs) from carbon, nitrogen and oxygen have been detected in 11 of them and neon ORLs in nine of them. All spectra were obtained by scanning a long slit across the nebular surface, yielding relative line inte…
The Hubble Deep Field North SCUBA Super-map - II. Multiwavelength properties
Nandra, Kirpal; Halpern, Mark; Chapman, Scott +3 more
We present radio, optical and X-ray-detected counterparts to the submillimetre sources found using SCUBA in the Hubble Deep Field North region (GOODS-N). A new counterpart identification statistic is developed to identify properties of galaxies detected at other wavelengths that can be used to aid counterpart identification. We discriminate betwee…
Confusion noise at far-infrared to millimetre wavelengths
Negrello, M.; Magliocchetti, M.; De Zotti, G. +3 more
We present detailed predictions for the confusion noise due to extragalactic sources in the far-infrared/(sub)millimetre channels of the ESA/ISO, NASA/Spitzer, ESA/Herschel and ESA/Planck satellites, including the contribution from clustering of unresolved SCUBA galaxies. Compared to the case of purely Poisson fluctuations, clustering is found to …
The European Large Area ISO Survey - VIII. 90-µm final analysis and source counts
Pérez-Fournon, I.; Puget, J. -L.; del Burgo, C. +17 more
We present a re-analysis of the European Large Area Infrared Space Observatory (ISO) Survey (ELAIS) 90-µm observations carried out with ISOPHOT, an instrument on board the ISO of the European Space Agency. With more than 12 deg2, the ELAIS survey is the largest area covered by ISO in a single programme and is about one order of ma…
The European Large Area ISO Survey - IX. The 90-µm luminosity function from the Final Analysis sample
Serjeant, Stephen; La Franca, Fabio; Oliver, Seb +18 more
We present the 90-µm luminosity function of the Final Analysis of the European Large Area ISO Survey (ELAIS), extending the sample size of our previous analysis (Paper IV) by about a factor of 4. Our sample extends to z= 1.1, ~50 times the comoving volume of Paper IV, and 107.7 < h-2L/Lsolar < 1012…
The spectral energy distributions of the revised 200-mJy sample
Bondi, M.; Browne, I. W. A.; Antón, S. +2 more
We address the question of why low-luminosity radio sources with similar flat radio spectra show a range of optical activity. The investigation is based on the spectral energy distributions (SEDs) of objects from the 200-mJy sample. We gathered new data from the VLA at 43 GHz, from SCUBA in the JCMT at 2000, 1350 and 850 µm, and from the ISO…
Present-day scaling relations for submillimetre galaxies: the origin of spheroidal systems
Takagi, T.; Hanami, H.; Arimoto, N.
We analyse the spectral energy distributions (SEDs) of 23 submillimetre galaxies and three ISO-detected extremely red objects, all of which have the spectroscopic redshifts, using an evolutionary SED model of starbursts. This SED model allows us to investigate the intrinsic properties of starbursts, such as the starburst age and the mean stellar m…
Large-scale structure in the ELAIS S1 Survey
Pozzi, F.; Vaccari, M.; Serjeant, S. +6 more
We present an analysis of the two-point angular correlation function of The European Large-Area Infrared Space Observatory (ELAIS) S1 survey. The survey covers 4 deg2 and contains 462 sources detected at 15 µm to a 5σ flux limit of 0.45 mJy. Using the 329 extragalactic sources not repeated in different observations, we detect a si…
