JWST is an absolute powerhouse. our color-magnitude diagrams are some of the deepest ever for galaxies within Virgo. these CMDs allow us to measure very precise TRGB distances.

Figure 5. Color magnitude diagrams for each of the ten galaxies presented in this paper. The CMDs for each of the two chips
are combined and displayed for each target, and the total number of stars is displayed in the top left. Only stars between 0.50
≤ F090W − F150W ≤ 1.75 mag were used for the determination of the TRGB, due to the downward sloping of the TRGB at
high metallicities, and hence colors (Anand et al. 2024a).

tying these distances together with ongoing SBF work from our group will allow us to set a very strong foundation for a high precision measurement of H0, comparable to what is achieved with Cepheids and supernovae
