Bright emission lines in eRASS1. The RGB map is composed of O VII (red), broadband emission in the 0.2–2.3 keV energy range (green), and the O VII/O VIII line ratio (blue). All the maps include the contribution of different components (both celestial and instrumental) and were smoothed with an adaptive kernel set to retrieve S/N threshold of 15.
