Reliability of the detection of the Baryon Acoustic Peak
Vicent J. Martinez, Pablo Arnalte-Mur, Enn Saar +5
The correlation function of the distribution of matter in the universe shows, at large scales, baryon acoustic oscillations, which were imprinted prior to recombination. This featu…
Measuring Baryon Acoustic Oscillations along the line of sight with photometric redshifs: the PAU survey
N. Benitez, E. Gaztanaga, R. Miquel +24
Baryon Acoustic Oscillations (BAO) provide a standard ruler of known physical length, making it a promising probe of the nature of dark energy. The detection of BAO requires measur…
Toward understanding rich superclusters
M. Einasto, E. Saar, V. J. Martinez +10
We present a morphological study of the two richest superclusters from the 2dF Galaxy Redshift Survey (SCL126, the Sloan Great Wall, and SCL9, the Sculptor supercluster). We use Mi…
Morphology of the galaxy distribution from wavelet denoising
V. J. Martinez, J. -L. Starck, E. Saar +4
We have developed a method based on wavelets to obtain the true underlying smooth density from a point distribution. The goal has been to reconstruct the density field in an optima…
Correlations at large scale
M. J. Pons-Borderia, V. J. Martinez, B. Lopez-Marti +1
We show point processes generated in different ways and having different structure, presenting very similar power-law two--point correlation functions at small scales and quite dif…
Multifractal fits to the observed main belt asteroid distribution
Adriano Campo Bagatin, Vicent J. Martinez, Silvestre Paredes
Dohnanyi's (1969) theory predicts that a collisional system such as the asteroidal population of the main belt should rapidly relax to a power-law stationary size distribution of t…
