Global radio and X-ray views of 4 × 4 degree region centered on SS 433 (both images are in Galactic coordinates). Left: Radio image (square-root scale) by Green Bank telescope at 6 cm(4.85 GHz, Gregory et al. 1996). Right: SRG/eROSITA (particle background-subtracted and exposure-corrected) 0.3−2.3 keV X-ray image (log scale, two-orders-of-magnitude range) of the W50 field, which combines the PV and all-sky data accumulated over four consecutive scans after smoothing using a Gaussian beam with σ=90 arcsec. The light blue areas in this image (where the X-ray flux is low) correspond to regions with high Galactic column density of gas and dust, which attenuate X-rays. Locations of supernova remnants 3C396, 3C397, and G038.7-01.3 (e.g., Green 2025), as well as of a HII region Sharpless 74 (Sharpless 1959) are marked on both images.
