Horizons: Exploring the Universe
Use the data in Figure 14-4 to plot a velocity-distance diagram, calculate the
Hubble constant H, and estimate the Hubble time. 2. If a galaxy is 9.0 Mpc away
from Earth and recedes at 510 km/s, what is H? What is the Hubble time? How
old ...

An Introduction to Galaxies and Cosmology
The Hubble constant is in many ways the most fundamental of the cosmological
parameters. Of them all, it is the one most easily related to the 'theoretical'
parameters that characterize the FRW models, and the value of H{, plays an
important ...
Mark H. Jones, Robert J. Lambourne, 2004
This classic text, aimed at senior undergraduates and beginning graduate students in physics and astronomy, presents a wide range of astrophysical concepts in sufficient depth to give the reader a quantitative understanding of the subject.

Confrontation of Cosmological Theories with Observational Data
A preliminary report is given of recent work with A. Sandage on the Hubble
constant. Through a chain of distance indicators in Sc and Ir galaxies (cepheids,
brightest stars. H n regions, and luminosity classes) the distance scale is carried

After the Science Wars: Science and the Study of Science
Since the Hubble constant measures the rate of expansion of the universe, these
possibilities show that the Hubble constant need not be a constant. In a universe
in which the expansion is slowing down, for example, the Hubble constant had ...

THE HUBBLE CONSTANT AND THE AGE OF THE UNIVERSE By knowing the
distances and speeds of the galaxies, we can, in principle, work out how much
time has elapsed since the Big Bang. If we assume that the galaxies have been ...

Astronomy: A Physical Perspective
As we will see below, the currently accepted value for the Hubble constant is in
the range 50-100 km/s/Mpc. Apart from telling us something interesting about the
universe, Hubble's law is also of great value when determining distances to ...

Sign-based Methods in Linear Statistical Models
However, Hubble's evaluations of distances have been reconsidered due to
subsequent developments in astronomy, which led to appreciable reduction of
the Hubble constant (which, however, does not affect the linear relationship itself)
