Total intensity images of TXS 2013+370 from 11 February 2021. Left: Observations at 22 GHz. Top-right: Observations at 43 GHz. Bottom-right: Observations at 86 GHz. Contours are at 0.5, 1, 2, 4, 8, 16, 32, and 64% of each panel’s peak (22: 1.33 Jy/beam; 43: 0.75 Jy/beam; 86: 0.71 Jy/beam). Restoring beams are shown as gray ellipses (parameters in Table 1). Orange circles mark MODELFIT Gaussian centroids. The 43 GHz map resolves a new knot (N2) near the core. At 86 GHz, the compact core and components (A2, C3, and N2) are clearly detected.
