Schematic illustration of the bow-tie around V4641 Sgr in the plane of the sky. In our model, the geometry of the bow-tie is a cone of radius, R, and height, H, with V4641 Sgr at its vertex. The symmetry axis of the cone has a position angle of −50° E of N. φ is the projected opening angle of the structure. The black dot corresponds to the position of V4641 Sgr, while the direction of the 1999 radio jets (−18° E of N; Hjellming et al. 2000) is represented in dark blue. The pink shaded areas symbolize the gamma-ray bubbles (Alfaro et al. 2024; LHAASO Collaboration 2025; H.E.S.S. Collaboration 2025).
