Arp 299: a case study of one of the most luminous star-forming galaxies
Abstract
We propose a 100ksec ACIS-S observation of Arp299 the second most X-ray luminous starburst galaxy in the local Universe. Short XMM and Chandra observations showed: one (and possibly two) AGN(s), a large population of ULXs and a luminous hot gaseous component. These characteristics together with its high star-formation rate make it one of the very few local analogs of high-z normal galaxies detected in deep X-ray surveys. This observation will allow us to: i) characterize the two nuclei and measure their contribution to the energy output of the system; ii) study its population of X-ray sources, providing a benchmark for the ULX populations at very high SFR; iii) investigate the hot gaseous component associated with the system, possibly related with a galactic scale outflow.
