1. ELAIS: final band-merged catalogue
ID:
ivo://CDS.VizieR/J/MNRAS/351/1290
Title:
ELAIS: final band-merged catalogue
Short Name:
J/MNRAS/351/1290
Date:
21 Oct 2021
Publisher:
CDS
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:
ISOCAM observations in Cha I.
Short Name:

Publisher:
CDS
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.

Description:
File table1 contains the list of the 212 ISOCAM sources recognized as members of the rho Ophiuchi embedded cluster. It lists their J2000 coordinates, flux densities at 6.7 and 14.3 micron and associated rms uncertainties, as well as the corresponding near-infrared identifications and the adopted IR classes (Class I, II or III).
4. ISOCAM survey of YSOs in Serpens Cloud Core
ID:

Title:
ISOCAM survey of YSOs in Serpens Cloud Core
Short Name:
J/A+A/421/623
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present results from an ISOCAM survey in the two broad band filters LW2 (5-8.5{mu}m) and LW3 (12-18{mu}m) of a 0.13 square degree coverage of the Serpens Main Cloud Core. A total of 392 sources were detected in the 6.7{mu}m band and 139 in the 14.3{mu}m band to a limiting sensitivity of ~2mJy. We identified 53 Young Stellar Objects (YSOs) with mid-IR excess from the single colour index [14.3/6.7], and 8 additional YSOs from the H-K/K-m_6.7_ diagram. Only 32 of these 61 sources were previously known to be YSO candidates.
5. ISO continuum observations of quasars

Title:
ISO continuum observations of quasars
Short Name:
J/A+A/365/409
Date:

Publisher:
CDS
Description:
Eight luminous quasars with -30<M_B_<-27 at z=1.4-3.7 have been observed in the mid- and far-infrared using ISO. All the quasars have been detected in the mid-infrared bands of ISOCAM, while no far-infrared detections have been made with ISOPHOT. SEDs (Spectral Energy Distributions) from the UV to far-infrared have been obtained while supplementing ISO observations with photometry in the optical and near-infrared made from the ground within 17 months. The SEDs are compared with the MED (Mean spectral Energy Distributions) of low-redshift quasars with -27<M_B_<-22. It is shown that our far-infrared observations were limited by confusion noise due to crowded sources.
6. ISOGAL sources in intermediate bulge fields

Title:
ISOGAL sources in intermediate bulge fields
Short Name:
J/A+A/403/141
Date:

Publisher:
CDS
Description:
We present a study of ISOGAL sources in the "intermediate" galactic bulge (|l|<2{deg}, |b|~1{deg}-4{deg}), observed by ISOCAM at 7 and 15{mu}m. In combination with near-infrared (I, J, Ks) data of DENIS survey, complemented by 2MASS data, we discuss the nature of the ISOGAL sources, their luminosities, the interstellar extinction and the mass-loss rates. A large fraction of the 1464 detected sources at 15{mu}m are AGB stars above the RGB tip, a number of them show an excess in ([7]-[15])_0_ and (Ks-[15])_0_ colours, characteristic of mass-loss. The latter, especially (Ks-[15])_0_, provide estimates of the mass-loss rates and show their distribution in the range 10^-8^ to 10^-5^M_{sun}_/yr.

Title:
ISO long period variables in SMC
Short Name:

Date:

Publisher:
CDS
Description:
This article presents the study of the light curves extracted from the MACHO database of a sample of stars observed by the Infrared Space Observatory in the Small Magellanic Cloud. These stars belong to the ISO Mini-Survey catalogue of the Magellanic Clouds (ISO MCMS, Loup et al., in preparation). Most of them are in the asymptotic giant branch (AGB) and supergiant phases. The dominant period and amplitude of pulsation have been derived and the stars have been classified as Mira or Semi Regular pulsators.
8. The ISOGAL Point Source Catalogue - IGPSC

Title:
The ISOGAL Point Source Catalogue - IGPSC
Short Name:
II/243
Date:

Publisher:
CDS
Description:
The ISOGAL survey is one of the largest imaging programme performed by the ISO satellite. About 16deg^2^ mainly distributed in the inner Galactic disk were mapped at 7 and/or 15 micron ({mu}m). Because of highly structured background and high source density, a special point source extraction algorithm was used and resulted in a 100000 point source catalogue. The mid-infrared data have been associated with near-infrared DENIS sources, providing an up to five wavelength photometric catalogue with a typical astrometric accuracy better than 1 arcsecond. The point source catalogue contains the positional and photometric parameters of all ISOGAL sources, together with various quality flags aimed at giving an estimate of the reliability of the detections and of the associations between the different bands (see the paper for a complete description).

Title:
YSOs in the l=+45 ISOGAL field

Description:
The 7 and 15{mu}m observations of the Galaxy obtained by the ISOGAL program offer an unique possibility to investigate and separate the different populations of stars in the Galactic Plane, in particular to study the population of low flux density YSOs which could not be detected with IRAS.
