FEASTS: Radial Distribution of H i Surface Densities Down to 0.01 M⊙ pc−2 of 35 Nearby Galaxies

We present the H i surface density (Σ _H _i ) radial distributions based on total-power H i images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72°. We derive the H i radius R _001 , which is the radius for the 0.01 M _⊙ pc ^−2 (~10 ^18.1 cm ^−2 ) isodensity l...
