False color image of Vela Jr. The energy of the X-ray photons are color-coded: red (0.2–0.7 keV), green (0.7–1.2 keV), and blue (1.2–8.0 keV). In order to enhance the visibility of the diffuse X-ray emission, the images of the different bands were convolved with a Gaussian filter (expressed in pixels; red: radius = 7, σ = 3.5; green: radius = 8, σ = 4; blue: radius = 8, σ = 4).
