Abstract:
We present BAX, Base de Donnees Amas de Galaxies X
(http://bax.ast.obs-mip.fr), a multi-wavelength database dedicated to
X-ray clusters and groups of galaxies allowing detailed information
retrieval. BAX is designed to support astronomical research by
providing access to published measurements of the main physical
quantities and to the related bibliographic references: basic data
stored in the database are cluster/group identifiers, equatorial
coordinates, redshift, flux, X-ray luminosity (in the ROSAT band) and
temperature, and links to additional linked parameters (in X-rays,
such as spatial profile parameters, as well as SZ parameters of the
hot gas, lensing measurements, and data at other wavelengths, such as
optical and radio). The clusters and groups in BAX can be queried by
the basic parameters as well as the linked parameters or combinations
of these. We expect BAX to become an important tool for the
astronomical community. BAX will optimize various aspects of the
scientific analysis of X-ray clusters and groups of galaxies, from
proposal planning to data collection, interpretation and publication,
from both ground based facilities like MEGACAM (CFHT), VIRMOS (VLT)
and space missions like XMM-Newton, Chandra and Planck.
