Significance maps of LHAASO J1914+1050 (GRS 1915+105–LHAASO) observed with LHAASO-WCDA (upper panel) and with LHAASO-KM2A (lower panel). The dark-green circles indicate the measured source extension, centered on the dark-green cross. The radii of the circles are extension at 5 TeV (0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩354) and that at 100 TeV (0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩246). The cyan plus symbol marks the nominal position of GRS 1915+105, while the gray cross shows the source position reported in the previous LHAASO-KM2A measurement (LHAASO Collaboration 2025a). Light green plus symbols denote the positions of other known supernova remnants (SNRs) or pulsars, and cyan contour marks the jet–interstellar medium (ISM) interaction region observed by MeerKAT (S. E. Motta et al. 2025).
