Where are the First Stars now? (1999)
White, Simon D. M., Springel, Volker
We use high-resolution simulations to show that the current standard paradigm for the growth of structure in the Universe predicts the formation of a galaxy like our own to differ substantially from...
On the formation and evolution of galaxies / (1999)
München, University, Diss., 2000 (Nicht für den Austausch).
Dynamics of pairwise motions (1998)
Juszkiewicz, Roman, Springel, Volker, Durrer, Ruth
We derive a simple closed-form expression, relating $\vs(r)$ -- the mean relative velocity of pairs of galaxies at fixed separation $r$ -- to the two-point correlation function of mass density...
Tidal tails in CDM cosmologies (1998)
Springel, Volker, White, Simon D. M.
We study the formation of tidal tails in pairs of merging disk galaxies with structural properties motivated by current theories of cold dark matter (CDM) cosmologies. In a recent study, Dubinski,...
Genus statistics of the Virgo N–body simulations and the 1.2Jy redshift survey (1998)
Volker Springel, Jrg M. Colberg, George P. Efstathiou, Carlos S. Frenk, ...
We study the topology of the Virgo N-body simulations and compare it with the 1.2-Jy redshift survey of IRAS galaxies by means of the genus statistic. Four high-resolution simulations of variants of...
Estimates for the Luminosity Function of Galaxies and its Evolution (1997)
Springel, Volker, White, Simon D. M.
A new method is presented to obtain a non-parametric maximum likelihood estimate of the luminosity function and the selection function of a flux limited redshift survey. The method parameterizes the...
