Description:
ESA's Infrared Space Observatory (ISO) was used to perform a deep survey with ISOCAM through three massive gravitationally lensing clusters of galaxies. The total area surveyed depends on source flux, with nearly seventy square arcminutes covered for the brighter flux levels in maps centred on the three clusters Abell 370, Abell 2218 and Abell 2390. We present maps and photometry at 6.7um (hereafter 7um) and 14.3um (hereafter 15um), showing a total of 145 mid-infrared sources and the associated source counts.

Description:
We present the results of mapping observations with ISO of [OI]63{mu}m, 145{mu}m, [NII]122{mu}m, [CII]158{mu}m, [SiII]35{mu}m, and H_2_9.66{mu}m line emissions for the Carina nebula, an active star-forming region in the Galactic plane. The observations were made for the central 40'x20' area of the nebula, including the optically bright HII region and molecular cloud lying in front of the ionized gas. Around the center of the observed area is the interface between the HII region and the molecular cloud which creates a typical photodissociation region (PDR).

Description:
The catalog represents the final band-merged European Large-Area ISO Survey (ELAIS) Catalogue at 6.7, 15, 90 and 175{mu}m, and the associated data at U, g', r', i', Z, J, H, K and 20cm. Details about the origin of the survey, the observations, data reduction and optical identification are described in the paper. In addition to fluxes in the radio, infrared and optical passbands, spectroscopic redshifts are tabulated, where available. For the N1 and N2 areas, the Isaac Newton Telescope ugriz Wide Field Survey permits photometric redshifts to be estimated for galaxies and quasars.

Title:
European Large-Area ISO Survey (ELAIS) Final Band-Merged Catalog
Short Name:
ELAISFBMC
Date:

Publisher:
NASA/GSFC HEASARC
Description:
This table contains the final band-merged European Large-Area ISO Survey (ELAIS) Catalog at 6.7, 15, 90 and 175 microns (um), 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 in the reference paper, and a summary of the area covered and the completeness limit for each infrared band is given. A detailed discussion of the band-merging and optical association strategy is given in the paper. The total catalog consists of 3762 sources. 23% of the 15-um sources and 75% of the 6.7-um sources are stars. In the paper, for extragalactic sources observed in three or more infrared bands, color-color diagrams are presented and discussed in terms of the contributing infrared populations. Spectroscopic redshifts are tabulated, where available. For the N1 and N2 areas, the Isaac Newton Telescope (INT) ugriz Wide Field Survey permits photometric redshifts to be estimated for galaxies and quasars. These agree well with the spectroscopic redshifts, within the uncertainty of the photometric method (~10% in (1 +z) for galaxies). There is a high proportion of ultraluminous infrared galaxies (ULIRGs, with log<sub>10</sub> of 1-1000 um luminosity L<sub>ir</sub> > 12.22) in the ELAIS Catalog (14% of 15-um galaxies with known z), many with Arp 220-like SEDs. 10% of the 15-um sources are genuine optically blank fields to r'= 24: these must have very high infrared-to-optical ratios and probably have z > 0.6, so are high-luminosity dusty starbursts or Type 2 AGN. Nine hyperluminous infrared galaxies (L<sub>ir</sub> > 13.22) and nine extremely red objects (EROs) (r-K > 6) are found in the survey. The latter are interpreted as ultraluminous dusty infrared galaxies at z ~ 1. The large numbers of ultraluminous galaxies imply very strong evolution in the star formation rate between z = 0 and 1. There is also a surprisingly large population of luminous (L<sub>ir</sub> > 11.5), cool (cirrus-type SEDs) galaxies, with L<sub>ir</sub> - L<sub>opt</sub> > 0, implying A<sub>V</sub> > 1. This table contains the total catalog of 3762 ELIAS band-merged sources. This table was created by the HEASARC in October 2012 based on CDS Catalog J/MNRAS/351/1290 files catalog.dat (3523 sources) and unassoc.dat (239 sources). This is a service provided by NASA HEASARC .

Publisher:
CDS
Description:
We present the catalogs and source counts for the C_90_ (reference wavelength of 90um) and C_160_ (170um) bands, which were extracted from our analysis of an ISO deep far-infrared survey conducted as part of the Japan/UH ISO cosmology project. The total survey area is ~0.9deg^2^ in two fields within the Lockman Hole. The analysis consists of source extraction using the IRAF DAOPHOT package and simulations carried out by adding artificial sources to the maps to estimate the detection rate, the flux bias, the positional accuracy, and the noise.

Final analysis of ELAIS 15-{mu}m

CDS
Description:
We present the final analysis of the European Large Area Infrared Space Observatory (ISO) Survey (ELAIS) 15-{mu}m observations, carried out with the ISO Camera (ISOCAM) instrument on board the ISO. The data-reduction method, known as the Lari Method, is based on a mathematical model of the behaviour of the detector and was specifically designed for the detection of faint sources in ISOCAM/ISO Photopolarimeter (ISOPHOT) data. The method is fully interactive and leads to very reliable and complete source lists. The resulting catalogue includes 1923 sources detected with signal-to-noise ratio of >5 in the 0.5-100mJy flux range and over an area of 10.85deg^2^ split into four fields, making it the largest non-serendipitous extragalactic source catalogue obtained to date from the ISO data.

Title:
ISO Astrophysical Spectroscopic Database
Short Name:
III/242
Date:

Publisher:
CDS
Description:
This database will eventually contain all the published infrared lines observed by ISO, the Infrared Space Observatory. At this stage only a few percent of the total content is included but it is increasing steadily. Thus what is presented at this stage is a beta-version of the final product. ISO - the Infrared Space Observatory - was operational during about 28 months, between November 1995 and May 1998, until its cooling fluid (liquid helium) burnt out (Kessler et al. 1996A&A...315L..27K). It was the first far-infrared satellite equipped with two medium and high resolution spectrometers, SWS (Short Wavelength Spectrometer, 2.38-45.2{mu}m, de Graauw et al. 1996A&A...315L..49D) and LWS (Long Wavelength Spectrometer, 43-197{mu}m, Clegg et al. 1996A&A...315L..38C). Both spectrometers could be operated in grating or Fabry-Perot mode. In addition, the two other ISO instruments also provided spectroscopic data: ISOCAM (the ISO Camera, Cesarsky et al. 1996A&A...315L..32C) had a CVF (Circular Variable Filter) mode in 3 bands covering the range 2.3-17.3{mu}m, and ISOPHOT (The Imaging Photo-Polarimeter, Lemke et al. 1996A&A...315L..64L) had a dual grating spectrometer (PHOT-S) with resolving power of order 90 in two bands (2.5-4.9{mu}m and 5.8-11.6{mu}m). Detailed information about ISO and its four ISO instruments can be found in "The ISO Handbook" available on-line at http://www.iso.vilspa.esa.es/ The novelty, the richness and the unicity of the ISO spectroscopic data is what motivated us in compiling this data in a systematic and homogeneous way in order to make it available to the whole astronomical community. No other past, current or foreseen space project will overwrite this data, hence the importance of this compilation. In addition, queries on the database content will be a useful tool for the preparation of follow-up observations with other space, airborne or ground-based observatories such as Herschel, SOFIA, ALMA, VLT and more. In this early version, the database is very incomplete. It contains about 3000 lines which represents only a few percent of the total. Each observed and published ISO spectroscopic line corresponds to a physical line in IASD with up to 39 parameter/information fields. The description of the various columns is given below.
8. ISOCAM 14.3{mu}m Deep Survey in Lockman Hole

Title:
ISOCAM 14.3{mu}m Deep Survey in Lockman Hole
Short Name:
J/A+A/427/773
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a new analysis of the ISOCAM 14.3{mu}m deep survey in a 20x20 square arcmin area in the Lockman Hole. This survey is intermediate between the ultra-deep surveys and the shallow surveys in the ELAIS fields. The data have been analyzed with the method presented by Lari et al. (2001, Cat. <J/MNRAS/325/1173>). We have produced a catalogue of 283 sources detected above the 5-{sigma} threshold, with fluxes in the interval 0.1-8mJy. The catalogue is 90% complete at 1mJy. The positional accuracy, estimated from the cross-correlation of infrared and optical sources, is around 1.5arcsec. The search for the optical counterparts of the sources in the survey is performed on a medium-deep r' band optical image (5{sigma} depth of r'=25), making use of the radio detections when available. The photometry has been checked through simulations and by comparing the data with those presented in a shallower and more extended ISOCAM survey in the Lockman Hole, that we have presented in a companion paper. Only 15% of the 14.3{mu}m sources do not have an optical counterpart down to r'=25mag. We use the 6.7/14.3{mu}m colour as a star/galaxy separator, together with a visual inspection of the optical image and an analysis of the observed Spectral Energy Distribution of the ISOCAM sources. The stars in the sample turn out to be only 6% of the sample. We discuss the 14.3{mu}m counts of extragalactic sources, combining our catalogue with that obtained from the shallower ISOCAM survey. The data in the two surveys are consistent, and our results fully support the claims in previous works for the existence of an evolving population of infrared galaxies, confirming the evident departure from non-evolutionary model predictions.

Title:
ISOCAM observations in Cha I.

Description:
We present the results of an ISOCAM survey of the Chamaeleon I dark cloud conducted in two broad-band filters at 6.7 and 14.3{mu}m. In an area of 0.59deg^2^. we have detected a total of 282 mid-IR sources with 103 sources observed in both filters. Combining the ISOCAM observations with the I, J, and K_s_ data obtained with DENIS, we have found 108 pre-main-sequence (PMS) stars in the region, of which 34 were previously unidentified. Several of these newly discovered young stellar objects are relatively faint suggesting a population in Cha I of very low mass objects that probably includes brown dwarfs in their early contraction phases. Finally, most of the PMS stars show the spectral index computed between 2.2 and 14.3{mu}m typical of Class II sources. The luminosity function (LF) derived for our detected PMS stars is discussed.
