GMRT H I 21 cm velocity moment images of NGC 4141 at an angular resolution of ﹩10\mathop{.}\limits^{^{\prime\prime} }0﹩. (A) The velocity-integrated moment-0 image, on a color scale and using contours. The lowest contour is at the 3σ H I column density sensitivi of the spectral cube, 1.3 × 10²⁰ cm⁻² per 10.4 km s⁻¹, with subsequent contours increasing in steps of 3.5 × 10²⁰ cm⁻² (i.e., 8σ); the highest H I column density contour is at 3.2 × 10²¹ cm⁻². (B) The moment-0 image of (A) (contours), overlaid on the DECaLS g-band image (color scale; A. Dey et al. 2019). (C) The H I 21 cm velocity field; the velocity contours are at intervals of 15 km s⁻¹, with negative velocities indicated by dashed contours. (D) The H I 21 cm velocity dispersion map; the contours are at intervals of 10 km s⁻¹. In all panels, the axes are relative to the center of NGC 4141, with the magenta star indicating the location of FRB 20250316A, and the gray circle in the inset at the bottom left indicating the GMRT synthesized beam.
