XXL: The Ultimate XMM Extragalactic Survey
Start date: 03 May 2011
Address: Espace St Jacques, Bonifacio Corsica, Corsica, France
In December 2010, the XXL survey, an XMM-Newton Very Large Programme, has been granted time to map two extragalactic regions of 25 deg2, at a depth of ~5×10-15 erg/cm2/s (using 10 ks observations). While the main goal of the project is to constrain the Dark Energy equation of state using clusters of galaxies (cf. http://arxiv.org/abs/1009.3182), it will also have lasting legacy value for cluster scaling laws and studies of AGNs and XRB.
