The Hubble constant is the constant of proportionality between recession velocity and distance in the expanding universe. It is a fundamental property of cosmology that sets both the scale and the expansion age of the universe. It is determined by measurement of galaxy The Hubble constant is the constant of proportionality between recession velocity and development of new techniques for the measurements of galaxy distances, both calibration uncertainties and debates over systematic errors… 
The Hubble Constant
Considerable progress has been made in determining the Hubble constant over the past two decades. We discuss the cosmological context and importance of an accurate measurement of the Hubble constant,
Nearby galaxies. IV. The global Hubble parameter and the dispersion of the Hubble relation
Using a spherically symmetric model of the Virgo flow the global Hubble parameter has been estimated from the observed radial velocities and the photometrically measured distances of nearby galaxies.
The Origin of the Bimodal Distribution in the Estimates of the Hubble Constant
By the early 1970’s estimates of the Hubble constant from Sandage and Tammann were hovering around 55. On the other hand, VandenBerg and deVaucouleurs obtained values near 100. Even at the beginning
▪ Abstract A careful assessment of current uncertainties in stellar physics (opacities, nuclear reaction rates, equation of state effects, diffusion, rotation, and mass loss), in the chemistry of
The cosmic distance scale and the Hubble constant
Although astronomers can reliably measure the relative distances of distant galaxies, attempts to calibrate the absolute cosmic distance scale remain controversial. Nevertheless, the sources of
Direct geometrical measurement of the Hubble constant from galaxy parallax: predictions for the Vera C. Rubin Observatory and Nancy Grace Roman Space Telescope
We investigate the possibility that a statistical detection of the galaxy parallax shift due to the Earth's motion with respect to the CMB frame (cosmic secular parallax) could be made by the Vera C.
In the first fifty years after Edwin Hubble announced a linear relationship between distances and redshifts of external galaxies, the accepted value of his constant dropped by (or the Universe
Supernovae as Cosmological Probes
I review the use of SN Ia as distance indicators for measuring H0, the Hubble constant, and the expansion history of the Universe. Most current estimates of H0 are in the range 74–76
Cosmology after COBE—Review for particle physicists
I summarize the following current topics in cosmology: (1) The near-success of Cold Dark Matter (CDM) in predicting the COBE fluctuation amplitude, which favors the hypothesis that structure formed
Yellow Post-asymptotic-giant-branch Stars as Standard Candles. I. Calibration of the Luminosity Function in Galactic Globular Clusters
We use the results of a survey for low-surface-gravity stars in Galactic (and LMC) globular clusters to show that “yellow” post-asymptotic-branch (yPAGB) stars are likely to be excellent


Steps toward the Hubble constant. VIII - The global value
The problem of determining the global Hubble constant is approached by using two distance indicators whose dispersion in absolute magnitude is small, and hence which are virtually free of the
Zero point of the supernova Hubble diagram
An empirical calibration is presented for the absolute luminosity of type I supernovae using the most reliable distance estimates available to host galaxies of observed supernovae in the Virgo
Tests of Cosmological Models Constrained by Inflation
The inflationary scenario requires that the universe have negligible curvature along constant-density surfaces. In the Friedmann-Lemaitre cosmology that leaves us with two free parameters, Hubble's
Test for the cosmological constant with the number count of faint galaxies
Cosmological models are tested against the recent observations of the number count of faint galaxies by Tyson (1984) and of the redshift distribution of moderately faint galaxies by Broadhurst et al.
The surface brightness test for the expansion of the universe. II. Radii, surface brightness, and absolute magnitude correlations for nearby E galaxies
Data for elliptical galaxies in the Virgo, Fornax, and Coma clusters and in the general field are analyzed in order to determine the dispersion in average surface brightness. The data are discussed
Surface Brightness Fluctuations: A Bridge from M31 to the Hubble Constant
Observations of the I-band surface-brightness fluctuations of M32, M31, NGC 205, and other galaxies in the Fornax and Eridanus clusters are discussed. It is confirmed that M-bar(I) has a small
Gravitational lensing limits on the cosmological constant in a flat universe
Inflationary cosmological theories predict, and some more general aesthetic criteria suggest, that the large-scale spatial curvature of the universe k should be accurately zero (i.e., flat), a
An estimate of the Hubble constant from the gravitational lensing of quasar Q0957+561
THE double quasar Q0957+561 AB is believed to be a gravitationally lensed image formed by a galaxy at redshift z = 0.36: a single quasar at z = 1.41 is seen as two images because of the intevening
The extragalactic distance scale. II. The unbiased distance to the Virgo Cluster from the B-band Tully-Fisher relation
The behavior of the B-band Tully-Fisher (TF) relation with respect to the observational biases and parameter uncertainties is studied from an almost complete sample of spiral galaxies belonging to
A measurement of the value of the Hubble constant from the X-ray properties and the Sunyaev-Zel'dovich effect of Abell 665
A comparison of the X-ray properties and the Sunyaev-Zel'dovich (SZ) effect for a cluster of galaxies can be used to measure the distance of the cluster and hence the Hubble constant. This method was
