Future Evolution of Bound Superclusters in an Accelerating Universe
Pablo A. Araya-Melo, Andreas Reisenegger, Andres Meza +3
The evolution of marginally bound supercluster-like objects in an accelerating LambdaCDM Universe is followed, by means of cosmological simulations, from the present time to an exp…
Redshift-space limits of bound structures
Rolando Dünner, Andreas Reisenegger, Andrés Meza +2
An exponentially expanding Universe, possibly governed by a cosmological constant, forces gravitationally bound structures to become more and more isolated, eventually becoming cau…
The Limits of Bound Structures in the Accelerating Universe
Rolando Dünner, Pablo A. Araya, Andrés Meza +1
According to the latest evidence, the Universe is entering an era of exponential expansion, where gravitationally bound structures will get disconnected from each other, forming is…
Accretion relicts in the solar neighbourhood: debris from omegaCen's parent galaxy
Andres Meza, Julio F. Navarro, Mario G. Abadi +1
We use numerical simulations to investigate the orbital characteristics of tidal debris from satellites whose orbits are dragged into the plane of galactic disks by dynamical frict…
On the nature of the ring-like structure in the outer Galactic disk
Amina Helmi, Julio F. Navarro, Andres Meza +2
We examine the tidal disruption of satellite galaxies in a cosmological simulation of the formation of a disk galaxy in the CDM scenario. We find that the disruption of satellit…
Simulations of Galaxy Formation in a Lambda CDM Universe III: The Dissipative Formation of an Elliptical Galaxy
Andres Meza, Julio F. Navarro, Matthias Steinmetz +1
We examine in detail the dynamical structure of an elliptical galaxy simulated in the Lambda CDM scenario. The morphology of the galaxy evolves dramatically over time in response t…
