XMM-Newton/2dF survey. II.
Listed in IVOA Registry (Virtual Observatory)
In this paper we investigate the properties of low X-ray-to-optical flux ratio sources detected in a wide-area (2.5{deg}^2^) shallow [fX(0.5-8keV)~10^-14^erg/s/cm^2^] XMM-Newton survey.
Description
We find a total of 26 sources (5 per cent of the total X-ray-selected population) with log(fX)/f(opt)<-0.9 to the above flux limit. Optical spectroscopy is available for 20 of these low X-ray-to-optical flux ratio objects.
