Multiwavelength maps of the region around the giga-electronvolt excess: radio (VLA; left) and X-rays (XMM; right). The white marker represents the best-fit position of the giga-electronvolt excess, and the dotted curve is its localization error ellipse at a 95% confidence level. The cyan and green markers locate the nearby galaxies NGC 3191 and MCG+08-19-017, while the red and blue correspond to NVSS J101948+462332 and SDSS J101839.48+462315.8, respectively. White circles mark the quasars SDSS J101858.02+461812.3 and SDSS J101918.93+462301.4 discussed by Li et al. (2026).
