Primordial Nucleosynthesis of 7Lit exception between the atmospheric Li/H ratio and Te, and (2) at Te and (2) at T ≤ 5600 K the average lithium abundance is <Li/H> = 1.2 ± 0.3 x .. The latter value constitutes a lower limit on the ^Li fraction produced in primordial nucleosynthesis and thereby significantly constrains the cosmic ratio of baryons to photons.

Observational Cosmology 1920–1985: An Introduction to the Conferenceed as they have been discussed in the archive literature. The problem of observational bias is emphasized, as is the difficult recent search for secular evolutionary effects. Current problems which have prospects for solutions in the next decades are set out in the final section.

1743-9213 he observational aspects of modern cosmology was taken in part because this conference has come in a period when there have been several international meetings on one aspect of modern cosmology, namely the early universe and its possible relationship to particle physics. While that approach is extre

The Status of the Hubble Diagram In 1986volution effects, which dominate over the cosmological model differences. Most radio galaxies apparently have had active star formation, with a continually declining rate, but a few are quite faint and red; they may have had a relatively passive evolution.

The Cosmic Microwave Backgroundcale angular distribution are described, as well as searches for small angular scale fluctuations on arcsecond to degree scales. A few of the consequences of these measurements and upper limits for cosmology, astrophysics, and theories of galaxy formation are touched on here.

High Sensitivity Observations of the Microwave Background Radiationevolves into the present-day Universe (z = 0). Such measurements provide stringent tests of the cosmological theories of universal evolution and have implications for allowed values of the density and composition of matter in the Universe.
