The 3-point function in the large scale structure: I. The weakly non-linear regime in N-body simulations
J. Barriga, E. Gaztanaga
This paper presents a comparison of the predictions for the 2 and 3-point correlation functions of density fluctuations, xi_2 and xi_3, in gravitational perturbation theory (PT) ag…
Evidence for an inflationary phase transition from the LSS and CMB anisotropy data
J. Barriga, E. Gaztanaga, M. G. Santos +1
In the light of the recent Boomerang and Maxima observations of the CMB which show an anomalously low second acoustic peak, we reexamine the prediction by Adams et al (1997) that t…
On the APM power spectrum and the CMB anisotropy: Evidence for a phase transition during inflation?
Jose Barriga, Enrique Gaztanaga, Mario Santos +1
Adams et al. (1997b) have noted that according to our current understanding of the unification of fundamental interactions, there should have been phase transitions associated with…
Data Processing and Compression of Cosmic Microwave Background Anisotropies on Board the PLANCK Satellite
E. Gaztanaga, A. Romeo, J. Barriga +1
We present a simple way of coding and compressing the data on board the Planck instruments (HFI and LFI) to address the problem of the on board data reduction. This is a critical i…
Data compression on board the PLANCK Satellite Low Frequency Instrument: optimal compression rate
E. Gaztanaga, J. Barriga, A. Romeo +2
Data on board the future PLANCK Low Frequency Instrument (LFI), to measure the Cosmic Microwave Background (CMB) anisotropies, consist of differential temperature measurements,…
Information content in Gaussian noise: optimal compression rates
August Romeo, Enrique Gaztanaga, Jose Barriga +1
We approach the theoretical problem of compressing a signal dominated by Gaussian noise. We present expressions for the compression ratio which can be reached, under the light of S…
