XMM-Newton AO-13 closure

The XMM-Newton thirteenth Announcement of Opportunity (AO-13) closed on the 11th of October 2013.

In total, 452 valid proposals were submitted, requesting 77.7 Ms of science time. This Announcement of Opportunity covers a period of one year, with 14.5 Ms of observing time available for distribution. The over-subscription factor is 5.4.

A total of 56 proposals for Large Programmes were received. Triggered/ToO observations were requested in 51 proposals. For the joint programmes, 102 proposals were submitted: 18 requested time for the XMM-HST programme, 15 for the XMM-SWIFT programme, 8 for the XMM-VLT programme, 6 for the XMM-Chandra programme and 62 for the new XMM-NuSTAR programme.

SOC received proposals from 351 different principal investigators from 28 countries, mostly ESA member states, the United States, China and Japan. The number of countries involved increases to 37 if co- investigators are taken into account as well. Considering principal investigators and co-investigators, about 1500 individual scientists were involved in the response to the thirteenth Announcement of Opportunity.

Yours sincerely,
