The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe
galaxies:haloes cosmology:theory methods
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...
Short-lived star-forming giant clumps in cosmological simulations of z~2 disks
galaxies evolution— galaxies formation— galaxies high-redshift—galaxies structure
2010/11/9
Many observed massive star-forming z ≈ 2 galaxies are large disks that exhibit irregular morphologies, with ≈ 1 kpc, ≈ 108-10M⊙ clumps. We present high-resolution cosmological SPH simulations that zoo...
An exact cosmological solution of a Scalar-Tensor Gravity theory compatible with the $\Lambda$CDM model
exact cosmological solution Scalar-Tensor Gravity theory compatible $\Lambda$CDM model
2010/11/15
consider the massive Scalar-Tensor theory in the Jordan frame F() = K22,Z() = 1, and U() = (1/2)m22, F() corresponds to a constant Brans-Dicke parameter !BD = 1/4K2. The constaint of the solar s...
Anomalous parity asymmetry of WMAP power spectrum data at low multpoles: is it cosmological or systematics?
parity asymmetry cosmological WMAP power spectrum data
2010/3/8
We have investigated the odd-parity preference of the WMAP 7 year power spectrum. Our investigation shows parity asymmetry of the WMAP data (2<= l <=22) is anomalous at 4-in-1000 level. We also find i...
