ISO Status Report - November 2004
29 Nov 2004 14:33
Mission Status
The ISO Active Archive Phase Mid-Term Review was held on 14-15 June at ESAC.
The Board, composed of external data providers and users, was impressed with
the achievements of the ESA and National Data Centres over the past 2.5
years.
Their recommendations focused on making ISO data and results as widely
available as possible, by
concentrating the activities during the remaining 30 months on maximizing
the content and visibility of the Highly Processed Data Products, the result
of dedicated projects focused on cleaning the pipeline products from
residual instrumental artefacts
continuing with the integration of the ISO archive into the Virtual
Observatories,
ensuring prompt publication of the planned special issue of ISO Space
Science Reviews, a 400 pages book reviewing the results of ISO.
A new, major version of the ISO Data Archive (IDA) (Version 7) was released
on 8 June. This release includes enhanced quality information (important in
the Virtual Observatory context), a link to ISO catalogues based at the
Centre de Données Astronomique, Strasbourg, F and an improved postcard
server. Additionally, ISOPHOT catalogues, an atlas of combined SWS and LWS
observations of galactic HII regions and SWS observations of asteroids and
planetary satellites have been added as Highly Processed Data Products.
Science Highlights
ISO continues to have a significant presence in the refereed literature,
with 1160 papers published to date, embracing all areas of astronomy. Recent
papers report on:
The final band-merged European Large-Area ISO Survey (ELAIS) Catalogue
The ELAIS data at 6.7, 15, 90 and 175 µm, and the associated data at U, g',
r', i', Z, J, H, K and 20 cm are presented. The total Catalogue consists of
3762 sources. 23 per cent of the 15-µm sources and 75 per cent of the 6.7-µm
sources are stars. For extragalactic sources observed in three or more
infrared bands, colour-colour diagrams are presented and discussed in terms
of the contributing infrared populations. Spectral energy distributions
(SEDs) are shown for selected sources (Rowan-Robinson et al, MNRAS)
The catalogue of optically identified galaxies from the ISOPHOT 170µm
Serendipity Survey
The ISOPHOT Serendipity Sky Survey strip-scanning measurements covering ~15%
of the far-infrared (FIR) sky at 170 µm were searched for compact sources
associated with optically identified galaxies. A catalogue with 170 µm
fluxes for more than 1900 galaxies has been established. This is the only
currently available large-scale galaxy catalogue containing a sufficient
number of sources with 170 µm fluxes to allow further statistical studies of
various FIR properties. (Stickel et al., A&A) Additionally, a major review
paper (van Dishoeck, ARA&A) on "ISO Spectroscopy of Gas and Dust: from
Molecular Clouds to Protoplanetary Disks" has just been published. This
showcases the breadth and depth of observations made by the ISO
spectrometers in the 2.4-200 µm range of interstellar gas-phase and
solid-state species in the 2.4-200 µm range.
