Why does the clustering of haloes depend on their formation history
H. B. Sandvik, O. Moeller, J. Lee +1
We discuss in the framework of the excursion set formalism a recent discovery from N-body simulations that the clustering of haloes of given mass depends on their formation history…
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…
The end of unified dark matter?
Havard Sandvik, Max Tegmark, Matias Zaldarriaga +1
Despite the interest in dark matter and dark energy, it has never been shown that they are in fact two separate substances. We provide the first strong evidence that they are separ…
