Scientific paper

A recent Chandra observation of the (ultra)luminous infrared galaxy (ULIRG) NGC6240 led to the detection that both nuclei of this galaxy are active. X-rays are a powerful tool to track down obscured AGN. In order to search for more binary black holes, and for X-ray luminous starbursts, we propose to observe with Chandra `NGC 6240-like ULIRGs', carefully selected from a complete sample of (ultra)luminous IRAS galaxies. Results will be used to address the following key questions: are binary AGN a common (and perhaps universal) feature of luminous IRAS galaxies, and if so, when and at what level is the AGN activity triggered in each nucleus ? Can the fueling/growth of massive black holes be correlated in time with the merger phase ?
