    "abstract": "We revisit the work [L. Campos and J. Murphy, SIAM J. Math. Anal., 55 (2023), pp. 3807--3843], which classified the dynamics of $H^1$ solutions at the ground state threshold for cubic inhomogeneous nonlinear Schr\\\"odinger equations of the form $i\\partial_t u + \\Delta u + |x|^{-b}|u|^2 u = 0$ in the range $b\\in(0,\\tfrac12)$. By modifying the modulation analysis and using Strichartz estimates in place of pointwise bounds, we extend the result to the full energy-subcritical range $b\\in(0,1)$. This strategy is expected to carry over to other dispersive equations with singular potentials.",
