Simulations of damped Ly alpha and Lyman limit absorbers in different cosmologies: Implications for structure formation at high redshift
formation large scale structure of the Universe
2014/12/26
We use hydrodynamic cosmological simulations to study damped Lyα (DLA) and Lyman limit (LL) absorption at redshifts z = 2-4 in five variants of the cold dark matter scenario: COBE-normalized (CCDM), c...
Impact of Primordial Ultracompact Minihaloes on the Intergalactic Medium and First Structure Formation

2010/11/12
The effects of dark matter annihilation on the evolution of intergalactic medium(IGM) in the early Universe can be more important if dark matter structure is more concentrated. Ultracompact Minihaloes...

Scalar models generalized Chaplygin gas structure formation constraints
2010/11/9
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark
energy. It is characterized by a fluid with an equation of state p = −A/ . It can be obtained from a ge...

Shocks that arise from baryonic in-fall and merger events during
the structure formation are believed to be a source of cosmic rays. These "struc-
ture formation cosmic rays" (SFCRs) would essential...
