Scientific paper

We propose to obtain X-ray images and spectra of a sample of close pairs of similar sized interacting galaxies. The pairs were selected morphologically not to be tidally disrupted and to have separations or "activation distance" between about 10 and 100 kpc. We expect to detect an active nucleus in both galaxies of the pairs, which would confirm that this "activation distance" is instrumental in the activation of quiescent black holes during this intermediate stage of the merging evolution. The confirmation of such an "activation distance" is also relevant for categorizing binary quasars at higher redshifs that could be mis- interpreted as cases of gravitational lenses. We propose here to observe with Chandra 9 pairs that are closer together than about 20".
