Determination of the Local Hubble Constant from Virgo Infall Using TRGB
  Distances
  An independent determination of $H_0$ is crucial given the growing tension
between the Hubble constant, $H_0$, derived locally and that determined from
the modeling of the cosmic microwave background (CMB) originating in the early
universe. In this work, we present a new determination of $H_0$ using
velocities and tip of the red giant branch (TRGB) distances to 33 galaxies
located between the Local Group and the Virgo cluster. We use a model of the
infall pattern of the local Hubble flow modified by the Virgo mass, which is
given as a function of the cosmological constants ($H_0$, $\Omega_\Lambda$),
the radius of the zero-velocity surface $R_0$, and the intrinsic velocity
dispersion, $\sigma_v$. Fitting velocities and TRGB distances of 33 galaxies to
the model, we obtain $H_0 =$ 65.8 $\pm$ 3.5($stat$) $\pm$ 2.4($sys$) km
s$^{-1}$ Mpc$^{-1}$ and $R_0 =$ 6.76 $\pm$ 0.35 Mpc. Our local $H_0$ is
consistent with the global $H_0$ determined from CMB radiation, showing no
tension. In addition, we present new TRGB distances to NGC 4437 and NGC 4592
which are located near the zero-velocity surface: D = 9.28 $\pm$ 0.39 Mpc and D
= 9.07 $\pm$ 0.27 Mpc, respectively. Their spatial separation is
0.29$^{+0.30}_{-0.03}$ Mpc, suggesting that they form a physical pair.
