Testing the CMB Data for Systematic Effects
Louise M. Griffiths, Charles H. Lineweaver
Under the assumption that the concordance Lambda-cold dark matter (CDM) model is the correct model, we test the cosmic microwave background (CMB) anisotropy data for systematic eff…
Is the Pre-WMAP CMB Data Self-consistent?
Charles H. Lineweaver, Louise M. Griffiths
Although individual observational groups vigorously test their data sets for systematic errors, the pre-WMAP CMB observational data set has not yet been collectively tested. Under…
Constraining CMB-consistent primordial voids with cluster evolution
H. Mathis, J. Silk, L. M. Griffiths +1
Using cosmological simulations, we make predictions for the distribution of clusters in a plausible non-gaussian model where primordial voids nucleated during inflation act togethe…
Testing the CMB Data for Systematic Effects
Louise M. Griffiths, Charles H. Lineweaver
Under the assumption that the concordance Lambda cold dark matter (CDM) model is the correct model, we test the cosmic microwave background (CMB) anisotropy data for systematic eff…
A possible contribution to CMB anisotropies at high l from primordial voids
L. M. Griffiths, M. Kunz, J. Silk
We present preliminary results of an analysis into the effects of primordial voids on the cosmic microwave background (CMB). We show that an inflationary bubble model of void forma…
The effect of reionization on the COBE normalization
Louise M Griffiths, Andrew R Liddle
We point out that the effect of reionization on the microwave anisotropy power spectrum is not necessarily negligible on the scales probed by COBE. It can lead to an upward shift o…
CMB Constraints on a Baryonic Dark Matter-Dominated Universe
Louise M Griffiths, Alessandro Melchiorri, Joseph Silk
In recent years, upper limits on the cosmic microwave background (CMB) anisotropies combined with predictions made by theories of galaxy formation, have been extremely powerful in…
From Anisotropy to Omega
Alessandro Melchiorri, Louise M. Griffiths
Following the recent measurement of the acoustic peak by the BOOMERanG and MAXIMA experiments in the CMB anisotropy angular power spectrum, many analyses have found that the geomet…
Bumpy Power Spectra and dT/T
Louise M. Griffiths, Joseph Silk, Saleem Zaroubi
With the recent publication of the measurements of the radiation angular power spectrum from the BOOMERanG Antarctic flight (de Bernardis et al. 2000), it has become apparent that…
Cosmic microwave background constraints on the epoch of reionization
Louise M Griffiths, Domingos Barbosa, Andrew R Liddle
We use a compilation of cosmic microwave anisotropy data to constrain the epoch of reionization in the Universe, as a function of cosmological parameters. We consider spatially-fla…
