The CMB cold spot: texture, cluster or void?
M. Cruz, E. Martinez-Gonzalez, P. Vielva +3
The non-Gaussian cold spot found in the WMAP data has created controversy about its origin. Here we calculate the Bayesian posterior probability ratios for three different models t…
Observing high redshift galaxy clusters through lensing of the Ostriker-Vishniac effect
J. M. Diego, D. Herranz
In this paper we study the possibility of detecting lensing signals in high-resolution and high-sensitivity CMB experiments. At scales below 1 arcmin, the CMB background is dominat…
Combined reconstruction of weak and strong lensing data with WSLAP
J. M. Diego, M. Tegmark, P. Protopapas +1
We describe a method to estimate the mass distribution of a gravitational lens and the position of the sources from combined strong and weak lensing data. The algorithm combines we…
Non-parametric mass reconstruction of A1689 from strong lensing data with SLAP
J. M. Diego, H. B. Sandvik, P. Protopapas +3
We present the mass distribution in the central area of the cluster A1689 by fitting over 100 multiply lensed images with the non-parametric Strong Lensing Analysis Package (SLAP,…
Non-parametric inversion of strong lensing systems
J. M. Diego, P. Protopapas, H. B Sandvik +1
We revisit the issue of non-parametric gravitational lens reconstruction and present a new method to obtain the cluster mass distribution using strong lensing data without using an…
On the excess of power in high resolution CMB experiments
J. M. Diego, P. Vielva, E. Martinez-Gonalez +1
We revisit the possibility that an excess in the CMB power spectrum at small angular scales (CBI, ACBAR) can be due to galaxy clusters (or compact sources in general). We perform a…
