Galaxy groups in the 2dF galaxy redshift survey: A Compactness Analysis of Groups

A. Zandivarez, M. J. L. Dominguez, C. J. Ragone +2

A comprehensive study on compactness has been carried out on the 2dF Galaxy Group Catalogue constructed by Merchán & Zandivarez. The compactness indexes defined in this work take i…

Simulations of Galaxy Formation in a Lambda CDM Universe II: The Fine Structure of Simulated Galactic Disks

Mario G. Abadi, Julio F. Navarro, Matthias Steinmetz +1

We present a detailed analysis of the dynamical properties of a simulated disk galaxy assembled hierarchically in the Lambda CDM cosmogony. At z=0, two distinct dynamical component…

Galaxy Pairs in the 2dF Survey I. Effects of Interactions in the Field

D. G. Lambas, P. B. Tissera, M. Sol Alonso +1

We study galaxy pairs in the field selected from the 100 K public release of the 2dF galaxy redshift survey. Our analysis provides a well defined sample of 1258 galaxy pairs, a lar…

Simulations of Galaxy Formation in a Lambda CDM Universe I: Dynamical and Photometric Properties of a Simulated Disk Galaxy

Mario G. Abadi, Julio F. Navarro, Matthias Steinmetz +1

We analyze the properties of a disk galaxy simulated with unprecedented numerical resolution in the Lambda CDM cosmogony. The galaxy is assembled through a number of high-redshift…

Extrasolar Planets in Mean-Motion Resonance: Apses Alignment and Asymmetric Stationary Solutions

C. Beauge, S. Ferraz-Mello, T. A. Michtchenko

In recent years several pairs of extrasolar planets have been discovered in the vicinity of mean-motion commensurabilities. In some cases, such as the Gliese 876 system, the planet…

Nitrogen Abundances in DLA Systems: The Combined Effects of SNII and SNIa in a Hierarchical Clustering Scenario

P. B. Tissera, D. G. Lambas, S. A. Cora +1

The combined enrichment of Supernovae II and I in a hierarchical clustering scenario could produce regions with low N content respect to -elements consistent with observed value…
