Abstract: Who discovered the expanding universe? Was it Hubble, or Lemaitre, or was it just the end result of a long series of investigations? In this article we summarise the main steps and contribut...
The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe

2011/8/24
We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from...
The Distribution of Coalescing Compact Binaries in the Local Universe: Prospects for Gravitational-Wave Observations
gravitational waves — stars neutron — binaries general
2010/11/11
Merging compact binaries are the most viable and best studied candidates for gravitational wave
(GW) detection by the fully operational network of ground-based observatories. In anticipation of the f...
Testing gravity using the growth of large scale structure in the Universe
Methods numerical — Cosmology theory — dark energy
2010/11/15
Future galaxy surveys hope to distinguish between the dark energy and modified gravity
scenarios for the accelerating expansion of the Universe using the distortion of clustering in
redshift space. ...
