Watch how scientists filtered out possible sources of an X-ray signal called the iron K-alpha line in this animation. The first image shows the contours of the iron line observed in galaxy NGC 4945 with XMM-Newton.

Description
English: Watch how scientists filtered out possible sources of an X-ray signal called the iron K-alpha line in this animation. The first image shows the contours of the iron line observed in galaxy NGC 4945 with XMM-Newton. In the second image, the research team used data from Chandra to filter out sources like binary stars. In the final image, they removed X-rays from the galaxy’s active nucleus. The iron line still highlights a huge amount of cold gas in the galaxy.Video and stills are available for download.
