A measurement of Omega from the North American test flight of BOOMERANG
A. Melchiorri, P. A. R. Ade, P. de Bernardis +22
We use the angular power spectrum of the Cosmic Microwave Background, measured during the North American test flight of the BOOMERANG experiment, to constrain the geometry of the u…
Measurement of a Peak in the Cosmic Microwave Background Power Spectrum from the North American test flight of BOOMERANG
P. D. Mauskopf, P. A. R. Ade, P. de Bernardis +31
We describe a measurement of the angular power spectrum of anisotropies in the Cosmic Microwave Background (CMB) from 0.3 degrees to ~10 degrees from the North American test flight…
Tensor Microwave Anisotropies from a Stochastic Magnetic Field
R. Durrer, P. G. Ferreira, T. Kahniashvili
We derive an expression for the angular power spectrum of cosmic microwave background anisotropies due to gravity waves generated by a stochastic magnetic field and compare the res…
A Bayesian estimate of the skewness of the Cosmic Microwave Background
C. R. Contaldi, P. G. Ferreira, J. Magueijo +1
We propose a formalism for estimating the skewness and angular power spectrum of a general Cosmic Microwave Background data set. We use the Edgeworth Expansion to define a non-Gaus…
Simultaneous Estimation of Noise and Signal in Cosmic Microwave Background Experiments
Pedro G. Ferreira, Andrew H. Jaffe
To correctly analyse data sets from current microwave detection technology, one is forced to estimate the sky signal and experimental noise simultaneously. Given a time-ordered dat…
The 4 Year COBE DMR data is non-Gaussian
P. G. Ferreira, K. M. Gorski, J. Magueijo
I review our recent claim that there is evidence of non-Gaussianity in the 4 Year COBE DMR data. I describe the statistic we apply, the result we obtain and make a detailed list of…
Where is the COBE maps' non-Gaussianity?
Joao Magueijo, Pedro G. Ferreira, Krzysztof M. Gorski
We review our recent claim that there is evidence of non-Gaussianity in the 4 Year COBE DMR data. We present some new results concerning the effect of the galactic cut upon the non…
Gamma-ray bursts, axion emission and string theory dilaton
O. Bertolami
The emission of axions from supernovae is an interesting possibility to account for the Gamma-Ray Bursts provided their energy can be effectively converted into electromagnetic ene…
