The Cosmic Microwave Background Spectrum and an Upper Limit for Fractal Space Dimensionality
نویسنده
چکیده
The possibility to constrain fractal space dimensionality from Astrophysics and other areas is briefly reviewed. Using data from FIRAS instrument aboard COBE satellite and assuming space dimensionality to be 3 + ǫ, we calculate ǫ = −(0.957 ± 0.006) × 10 and an absolute temperature 2.726 ± 0.003 × 10 K by fitting the cosmic microwave background radiation spectrum to Planck’s radiation distribution. The upper limit for |ǫ|, shown to be similar to what was found based on microphysics, is interpreted as the maximum fluctuation space dimensionality should has undertook in a very large spatial and temporal scale compared to that of the decoupling era.

Estimates of maximum energy density of cosmological gravitational-wave backgrounds
The recent claim by BICEP2 of evidence for primordial gravitational waves has focused interest on the potential for early-Universe cosmology using gravitational waves. In addition to cosmic microwave background detectors, efforts are underway to carry out gravitational-wave astronomy with pulsar timing arrays, space-based detectors, and terrestrial detectors. These efforts will probe a wide ran...
متن کاملConstraints on the Evolution of the Primordial Magnetic Field from the Small-Scale Cosmic Microwave Background Angular Anisotropy
Recent observations of the cosmic microwave background (CMB) have extended the measured power spectrum to higher multipoles l &1000, and there appears to be possible evidence for excess power on small angular scales. The primordial magnetic field (PMF) can strongly affect the CMB power spectrum and the formation of large scale structure. In this paper, we calculate the CMB temperature anisotrop...
متن کاملCosmic microwave background power asymmetry from non-Gaussian modulation.
Non-Gaussianity in the inflationary perturbations can couple observable scales to modes of much longer wavelength (even superhorizon), leaving as a signature a large-angle modulation of the observed cosmic microwave background power spectrum. This provides an alternative origin for a power asymmetry that is otherwise often ascribed to a breaking of statistical isotropy. The non-Gaussian modulat...
متن کاملCausality and the Power Spectrum Typeset Using Revt E X 1
We nd constraints on the generation of super-causal-horizon energy perturbations from a smooth initial state, under a simple physical scheme. We quantify these constraints by placing the upper limit c ' 3:0d H on the wavelength at which the power spectrum turns over to k 4 behavior. This means that sub-horizon processes can generate signiicant power on scales further outside the horizon than on...
متن کاملContribution of long-wavelength gravitational waves to the cosmic microwave background anisotropy.
We present an in depth discussion of the production of gravitational waves from an inflationary phase that could have occurred in the early universe, giving derivations for the resulting spectrum and energy density. We also consider the large-scale anisotropy in the cosmic microwave background radiation coming from these waves. Assuming that the observed quadrupole anisotropy comes mostly from ...
