XMM-Newton observed the nearby edge-on galaxy NGC 4945 (D=4 Mpc) on July 5, 2022 for ~100 ksec. Left panel: A three color image from the EPIC pn with red = 0.5 to 1.5 keV, green = 1.5 to 5.0 keV, and blue = 5 to 8 keV. The image is smoothed with a Gaussian (radius = 10''). Right: The XMM OM image in the B filter (400 to 500 nm). Artifacts have not been corrected for. NGC 4945 hosts a powerful, X-ray variable AGN and has soft X-ray emission consistent with a starburst-driven outflow. The EPIC image shows many X-ray colors from the white and blue central core surrounding the AGN to the red extended soft X-ray emission from the starburst activity. NGC 4945 offers a nearby celestial laboratory to investigate the relationship between AGN and stellar feedback.
