The emptiness of voids: yet another over-abundance problem for the LCDM model
A. Tikhonov, A. Klypin
We study the luminosity function, the peculiar velocities, and the sizes of voids in the Local Volume (LV) in observational samples of galaxies which contain galaxies down to MB=-1…
Comparison of clustering properties of observed objects and dark matter halos on different mass and spatial scales
A. V. Tikhonov, A. I. Kopylov, S. Gottlober +1
We investigate the large-scale distribution of galaxy clusters taken from several X-ray catalogs. Different statistics of clustering like the conditional correlation function (CCF)…
Voids in the SDSS Galaxy Survey
Anton V. Tikhonov
Using the method of searching for arbitrary shaped voids in the distribution of volume-limited samples of galaxies from the DR5 SDSS survey, we have identified voids and investigat…
Voids in the Local Volume: a limit on appearance of a galaxy in a DM halo
Anton V. Tikhonov, Anatoly A. Klypin
Current explanation of the overabundance of dark matter subhalos in the Local Group (LG) indicates that there maybe a limit on mass of a halo, which can host a galaxy. This idea ca…
Properties of Voids in the 2dFGRS Galaxy Survey
Anton V. Tikhonov
A method for detecting voids in the galaxy distribution is presented. Using this method, we have identified 732 voids with a radius of the seed sphere Rseed > 4.0h^{-1}Mpc in a vol…
Correlation Properties of Galaxies from the Main Galaxy Sample of the SDSS Survey
Anton V. Tikhonov
The apparatus of correlation gamma function (Γ*(r)) is used to analyze volume-limited samples from the DR4 Main Galaxy Sample of the SDSS survey with the aim of determining the cha…
