| description | The project AMIGA (Analysis of the interstellar Medium of Isolated GAlaxies)
will provide a statistically significant sample of the most isolated galaxies
in the northern sky. Such a control sample is necessary to assess the role of
the environment in galaxy properties and evolution. The sample is based on the
Catalogue of Isolated Galaxies (CIG, Karachentseva, 1973) and the database will
include blue and near-infrared luminosities, far-infrared (FIR) emission,
atomic gas (HI) emission, radio continuum, and, for a redshift limited
subsample of about 200 galaxies, CO and H$\alpha$ emission. The data will be
released and periodically updated at http://www.iaa.csic.es/AMIGA.html. Here,
we present the project and its status, as well as a preliminary analysis of the
relation between star formation activity and the environment. We found a trend
that the galaxies with asymmetric HI spectrum also tend to show an enhanced
star formation, traced by a high value of $L_{FIR}/M(HI)$, indicating that a
perturbed gas kinematics and enhanced SF are related. |
