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 …
Exploring the Upper Red Giant and Asymptotic Giant Branches: The Globular Cluster M5
Bolte, Michael; Sandquist, Eric L.
We have tabulated lists of upper red giant, horizontal-, and asymptotic giant branch (RGB, HB, and AGB) stars in the globular cluster M5 that are complete to over 10' from the core for the RGB and AGB samples, and 8' for the HB sample. The large samples give us the most precise value of R2=NAGB/NHB to date for a si…
A deeper view of extremely red galaxies: the redshift distribution in the GOODS/CDFS ISAAC field
McLure, R. J.; Dunlop, J. S.; Caputi, K. I. +1 more
We have analysed five-epoch Great Observatories Origins Deep Survey (GOODS) HST-ACS B, V, I775 and z data sets (v. 1.0 release), in conjunction with existing VLT-ISAAC imaging in the J, H and Ks bands, to derive estimated redshifts for the sample of 198 extremely red galaxies (ERGs) with Ks < 22 (Vega) and (I
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…
Astrophysical lasers operating in optical Fe II lines in stellar ejecta of η Carinae
Johansson, S.; Letokhov, V. S.
After the discovery of space masers based on OH radicals (Weaver et al. \cite{Wea65}) and H2O (Cheung et al. \cite{Che69}) such microwave lasers have been found to work in more than 100 molecular species (Elitzur \cite{Eli92}; Townes \cite{Tow97}), as well as in highly excited H atoms (Strelnitski et al. \cite{Str96}). In the IR region …
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 XMM-Newton view of NGC 6251
Brandt, W. N.; Mushotzky, R.; Gliozzi, M. +2 more
We report on the nuclear X-ray properties of the radio galaxy
A search for clusters and groups of galaxies on the line of sight towards 8 lensed quasars
Faure, C.; Alloin, D.; Kneib, J. P. +1 more
In this paper we present new ESO/VLT FORS1 and ISAAC images of the fields around eight gravitationally lensed quasars: CTQ 414, HE 0230-2130, LBQS 1009-0252, B 1030+074, HE 1104-1805, B 1359+154, H 1413+117 and HE 2149-2745. When available and deep enough, HST/WFPC2 data were also used to infer the photometric redshifts of the galaxies around the …
The Canada-UK Deep Submillimetre Survey - VIII. Source identifications in the 3-hour field
Gear, Walter; Le Fèvre, Olivier; Dunne, Loretta +10 more
We present optical, near-infrared (IR) and radio observations of the 3-hour field of the Canada-UK Deep Submillimetre Survey (CUDSS). Of the 27 submillimetre sources in the field, nine have secure identifications with either a radio source or a near-IR source. We show that the percentage of sources with secure identifications in the CUDSS is consi…
XMM-Newton observations of the starburst merger galaxies NGC 3256 and NGC 3310
Zezas, A.; Roberts, T. P.; Ward, M. J. +1 more
We present XMM-Newton EPIC observations of the two nearby starburst merger galaxies NGC 3256 and NGC 3310. The broad-band (0.3-10 keV) integrated X-ray emission from both galaxies shows evidence of multiphase thermal plasmas plus an underlying hard non-thermal power-law continuum. NGC 3256 is well fitted with a model comprising two MEKAL component…
