However, the total CX flux and the regions where CX occurs have been poorly understood. We present an analysis of the {\\it XMM-Newton} observations of M82, a prototype starburst galaxy, aiming to investigate these key properties of the CX emisssion. We have used a blind source separation method in the image analysis with the CCD data which identified a component with the enhanced O-K lines expected from the CX process.
