Scientific paper

We present three-dimensional numerical simulations of the wind from the Arches cluster. In order to make the model as realistic as possible, we have placed stellar wind sources at the positions on the plane of the sky of the 60 brightest stars of the cluster and have calculated three different possible distributions of the stars along the line of sight. From the resulting flows, we have computed the X-ray emission, obtaining emission maps and (spatially integrated) spectra. These results are compared with the recent Chandra observations of the Arches cluster of Yusef-Zadeh and coworkers, and a good qualitative agreement is found.
