Intergalactic 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 کاملHeating of the Intergalactic Medium by Primordial Miniquasars
A simple analytical model is used to calculate the X-ray heating of the IGM for a range of black hole masses. This process is efficient enough to decouple the spin temperature of the intergalactic medium from the cosmic microwave background (CMB) temperature and produce a differential brightness temperature of the order of ∼ 5 − 20 K out to distances as large as a few co-moving Mpc, depending o...
متن کاملHeating the intergalactic medium by radiative decay of neutrinos
Assuming that there exists a species of heavy sterile neutrinos (mν > 1 keV) and their decays can serve as a heating source of the hot gas in galaxy clusters, we study how the observational constraints on cooling flow limit the mass of these sterile neutrinos. We predict a relation among the luminosity, total mass and the redshift of a cluster, and we compare this relation with data from 12 clu...
متن کاملOn the Cross-Correlation between Dark Matter Distribution and Secondary CMB Anisotropies by Ionized Intergalactic Medium
We investigate a cross-correlation between the weak gravitational lensing field of the largescale structure, κ, and the secondary temperature fluctuation field, ∆, of cosmic microwave background (CMB) induced by Thomson scattering of CMB photons off the ionized medium in the mildly nonlinear structure. The cross-correlation is expected to observationally unveil the biasing relation between the ...
متن کاملConstraints on Dark Matter annihilations from reionization and heating of the intergalactic gas
Dark Matter annihilations after recombination and during the epoch of structure formation deposit energy in the primordial intergalactic medium, producing reionization and heating. We investigate the constraints that are imposed by the observed optical depth of the Universe and the measured temperature of the intergalactic gas. We find that the bounds are significant, and have the power to rule...
