Abstract | We propose a 90ks XMM-Newton/EPIC observation of the Ultra-Luminous InfraredGalaxy Arp220,the nearest ULIG. Based on ASCA and BeppoSAX observations,if anAGN were the major evergy source in this object,it must be Compton-thick. A 50ksChandra observation has located a faint hard X-ray source at one of the doublenuclei, and the spectrum hinted at the presence of an iron K-line. The primaryaim of this proposal is to obtain a high quality iron K-line spectrum with theEPIC cameras in order to determine the origin of the hard X-ray emission, whichwe believe will provide the ultimate test as to whether an AGN powers theenormous infrared luminosity in this prototype ULIG, as well as have importantimplications for interpreting the X-ray emission from all ULIGs. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
