The origin of 'Great Walls' (2008)
A new semianalytical model that explains the formation and sizes of the 'great walls' - the largest structures observed in the universe is suggested. Although the basis of the model is the Zel'dovich...
The Aspen–Amsterdam Void Finder Comparison Project (2008)
Shandarin,Sergei, Porciani, Cristiano, Plionis, Manolis, Nelson, Lorne, M¨uller, V., Hoyle, Fiona, ...
Despite a history that dates back at least a quarter of a century studies of voids in the large–scale structure of the Universe are bedevilled by a major problem: there exist a large number of...

Dark matter caustics and the enhancement of self-annihilation flux (2007)
Mohayaee, Roya, Shandarin, Sergei, Silk, Joseph
Cold dark matter haloes are populated by caustics, which are yet to be resolved in N-body simulations or observed in the Universe. Secondary infall model provides a paradigm for the study of caustics...
Caustics in Dark Matter Haloes (2005)
Mohayaee, Roya, Colombi, Stephane, Fort, Bernard, Gavazzi, Raphael, Shandarin, Sergei, Touma, Jihad
Caustics are formally singular structures, with infinite density, that form in collisionless media. The non-negligible velocity dispersion of dark matter particles renders their density finite. We...
Shapes and Sizes of Voids in the LCDM Universe: Excursion Set Approach (2005)
Shandarin, Sergei, Feldman, Hume A., Heitmann, Katrin, Habib, Salman
We study the global distribution and morphology of dark matter voids in a LCDM universe using density fields generated by N-body simulations. Voids are defined as isolated regions of the low-density...
Gravitational cooling and density profile near caustics in collisionless dark matter haloes (2005)
Mohayaee, Roya, Shandarin, Sergei
Cold dark matter haloes are populated by high-density structures with sharply-peaked profiles known as caustics which have not yet been resolved by 3-dimensional numerical simulations. Here, we...
