Multiwavelength view of S147 (in Galactic coordinates). Top: combined map of the radio (CGPS data at 1.4 GHz, red), wavelet-decomposed (in order to emphasize filamentary structure) Hα (IGAPS data, green), and broadband X-ray (0.5–1.1 keV, SRG/eROSITA data, blue) emission. The white cross marks the position of PSR J0538+2817. Middle: the intensity-saturated X-ray image is shown in blue on top of the wavelet-decomposed Hα image, demonstrating that X-ray emission is confined by the Hα-emitting shell. Bottom: same as the middle panel but with the 1.4 GHz radio emission as a background.
