Abstract:
We obtained a sample of 143 normal galaxies with X-ray luminosity in
the range 1038-1043erg/s from the cross-correlation of the ROSAT
HRI Brera Multi-scale Wavelet (BMW-HRI) Catalogue with the Lyon-Meudon
Extragalactic Database (LEDA). We find that the average X-ray
properties of this sample are in good agreement with those of other
samples of galaxies in the literature. We selected a complete flux
limited serendipitous sample of 32 galaxies from which we derived the
logN-logS distribution of normal galaxies in the flux range
1.1-110x10-14erg/cm2/s. The resulting distribution is consistent
with the Euclidean -1.5 slope. Comparisons with other samples, such as
the Extended Medium Sensitivity Survey, the ROSAT All Sky Survey, the
XMM-Newton/2dF survey, and the Chandra Deep Field Survey indicate that
the logN-logS distribution of normal galaxies is consistent with a
Euclidean slope over a flux range of about 6 decades.
