چکیده

In this paper we show that, within the framework of the QSSC, the small scale deviations on angular scales ∼ < 1 expected in the MBR are due to inhomogeneities in the distribution of galaxies and clusters. It is shown how these can be estimated on the galaxy-cluster-supercluster scale at the epoch of redshift ∼ 5 when the universe was last passing through the minimum phase of the scale factor. Rich clusters on the scale of 5-10 Mpc generate the kind of peak in the fluctuation power spectru m observed by the Boomrang and Maxima projects. Weaker inhomogeneities on smaller scales with l ∼ 10 are expected to arise from individual galaxies and small groups. Subject headings: microwave background inhomogeneities, cosmology

We calculate the expected angular power spectrum of the temperature fluctuations in the microwave background radiation (MBR) generated in the quasi-steady state cos-mology (QSSC). The paper begins with a brief description of how the background is produced and thermalized in the QSSC. We then discuss within the framework of a simple model, the likely sources of fluctuations in the background due...

An Alternative Cosmology

Recent discussions of observational constraints on the standard hot big bang model are reviewed and it is argued that now there is room for considering alternative cosmologies. The quasi-steady state cosmology is brieey described. This model seems to explain most of the observed features of the universe, including the m-z relation, radio source count, the light nuclear abundances and the microw...

Cosmic Microwave Background Observations in the Era of Precision Cosmology

The cosmic microwave background (CMB) radiation is a major arena for testing cosmological theories. Its discovery confirmed the hot-bigbang origin of the universe and ruled out the steady-state theory. Since that time the impact on cosmology of CMB studies has grown steadily, indicating the prevalence of non-baryonic matter and the existence of a negative pressure component in the 1980’s; the d...

Polarization of the Microwave Background Due to Primordial Gravitational Waves

The contribution of gravitational wave (tensor metric) and energy density (scalar metric) fluctuations to the cosmic microwave background polarization is computed. We find that the tensor contribution is significant only at large angular scales (multipoles ` < ∼ 40). For standard recombination, the tensor contribution can dominate at ` < ∼ 40; however, the effect would be difficult to detect si...

Skewness of Cosmic Microwave Background Temperature Fluctuations Due to Non-linear Gravitational Instability

Skewness of temperature fluctuations of the cosmic microwave background (CMB) produced by initially Gaussian adiabatic perturbations with the flat (Harrison-Zeldovich) spectrum, which arises due to non-linear corrections to a gravitational potential at the matter-dominated stage, is calculated quantitatively. For the standard CDM model, the effect appears to be smaller than expected previously ...
