Observational Tests of Intergalactic Enrichment Models
We summarize recent results assessing the carbon and silicon abundances of the intergalactic medium (IGM) using the ‘pixel optical depth’ technique. We briefly discuss the implications of these results for models of intergalactic enrichment, focusing on distinguishing ‘early’ z ≫ 4 enrichment by the first generations of stars and objects from ‘late’ enrichment by 2 ∼ z ∼ 5 Lybreak galaxies. We ...
متن کاملObservational tests of x-matter models
We study gravitational lensing statistics, matter power spectra and the angular power spectra of the cosmic microwave background (CMB) radiation in x-matter models. We adopt an equation-of-state of x-matter which can express a wide range of matter from the pressureless dust to the cosmological constant. A new ingredient in this model is the sound speed of the x-component in addition to the equa...
متن کاملIntergalactic medium heating by dark matter
We derive the evolution of the energy deposition in the intergalactic medium (IGM) by dark matter (DM) decays/annihilations for both sterile neutrinos and light dark matter (LDM) particles. At z > 200 sterile neutrinos transfer a fraction fabs ∼ 0.5 of their rest mass energy into the IGM; at lower redshifts this fraction becomes < ∼ 0.3 depending on the particle mass. The LDM particles can deca...
متن کاملIntergalactic Matter And Cocoons of Radio Galaxies
The cocoons surrounding powerful radio sources can be extensive if the jet that feeds the cocoon is light and supersonic. They have been shown to remain overpressured with respect to the ambient medium for most of the life time of the sources. The observed lobes of the radio sources form parts of these extensive cocoons. We show that observations of the lobes of giant radio sources allow one to...
متن کاملObservational tests of inflation
We are on the verge of the first precision testing of the inflationary cosmology as a model for the origin of structure in the Universe. I review the key predictions of inflation which can be used as observational tests, in the sense of allowing inflation to be falsified. The most important prediction of this type is that the perturbations will cross inside the Hubble radius entirely in their g...
