COBE- and Cluster-Normalized CDM Simulations
Tsvi Piran, Hagai El-Ad, Hugo Martel +1
We introduce a set of four new publicly available N-body simulations, the most recent additions to the Texas P^3M Database. Our models probe the less studied parameter space region…
A case devoid of bias: ORS voids vs. IRAS voids
Hagai El-Ad, Tsvi Piran
We present a comparison between the voids in two nearly all sky redshift surveys: the ORS and the IRAS 1.2 Jy. While the galaxies in these surveys are selected differently and thei…
Voids in the Large-Scale Structure
Hagai El-Ad, Tsvi Piran
Voids are the most prominent feature of the LSS of the universe. Still, they have been generally ignored in quantitative analysis of it, essentially due to the lack of an objective…
A catalogue of the voids in the IRAS 1.2-Jy survey
Hagai El-Ad, Tsvi Piran, Luiz Nicolaci da Costa
Using the VOID FINDER algorithm we have compiled a catalogue of voids in the IRAS 1.2-Jy sample. The positions of the voids correspond well to underdense regions seen in the IRAS s…
Automated Detection of Voids in Redshift Surveys
Hagai El-Ad, Tsvi Piran, Luiz Nicolaci da Costa
We present a new void search algorithm for automated detection of voids in three-dimensional redshift surveys. Based on a model in which the main features of the LSS of the Univers…
