XMM-Newton AO-14 closure

The XMM-Newton fourteenth Announcement of Opportunity (AO-14) closed on the 10th of October 2014.

In total, 431 valid proposals were submitted, requesting 82 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 5.7.

A total of 52 proposals for Large Programmes were received. Triggered/ToO observations were requested in 59 proposals. For the joint programmes, 92 proposals were submitted: 13 requested time for the XMM-HST programme, 13 for the XMM-SWIFT programme, 6 for the XMM-VLT programme, 5 for the XMM-Chandra programme and 61 for the XMM-NuSTAR programme.

SOC received proposals from 344 different principal investigators from 32 countries, mostly ESA member states, the United States, Japan and China. The number of countries involved increases to 40 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 fourteenth Announcement of Opportunity.

Yours sincerely,
