The calibration of the Tully-Fisher relations and the value of Hubble Constant
conference contribution
posted on 2024-07-12, 14:43 authored by Shoko Sakai, Jeremy MouldJeremy Mould, John Huchra, Shaun Hughes, Lucas M. Macri, Robert C. KennicuttWe present the calibration of BV RIH -0.5 Tully-fisher relations based on Cepheid distances to 21 galaxies within 25Mpc. These relations are then applied to four distant cluster surveys (in B, R, I and H) to derive value of Ho. Taking a weighted average of the estimates we obtain Ho = 71 + 4 (random) + (systematic) km sec^-1 Mpc^-1. We also investigate how various sytematic uncertainties affect this value.
