Bounds on dark matter annihilation cross-sections from inert doublet model in the context of 21-cm cosmology of dark ages
نویسندگان
چکیده
We study the fluctuations in brightness temperature of 21-cm signal [Formula: see text] at dark ages ([Formula: text]) with a matter (DM) candidate Inert Doublet Model (IDM). then explore effects different fractions IDM DM on signal. The masses are chosen few tens GeV region as well high mass beyond 500 GeV. It has been observed that is more sensitive range 70–80 A lower bound annihilation cross-section for this also obtained by analyzing This found to lie within cm 3 /s 10 GeV[Formula:

Neutrinos from Inert Doublet Dark Matter
We investigate the signatures of neutrinos produced in the annihilation of WIMP dark matter in the Earth, the Sun and at the Galactic centre within the framework of the Inert Doublet Model and extensions. To accommodate the WMAP constraints, the dark matter candidate, which is one of the neutral components of an extra Higgs doublet, must have a mass in either one of three distinct mass ranges: ...
متن کاملDark Matter with Topological Defects in the Inert Doublet Model
We examine the production of dark matter by decaying topological defects in the high mass region mDM mW of the Inert Doublet Model, extended with an extra U(1) gauge symmetry. The density of dark matter states (the neutral Higgs states of the inert doublet) is determined by the interplay of the freeze-out mechanism and the additional production of dark matter states from the decays of topologic...
متن کاملConstraining dark matter through 21 cm observations
Beyond reionization epoch cosmic hydrogen is neutral and can be directly observed through its 21 cm line signal. If dark matter (DM) decays or annihilates the corresponding energy input affects the hydrogen kinetic temperature and ionized fraction, and contributes to the Lyα background. The changes induced by these processes on the 21 cm signal can then be used to constrain the proposed DM cand...
متن کاملRedshifted 21-cm Signals in the Dark Ages
We have carried out semianalytic simulations to build redshifted 21-cm maps in the dark ages. An entropy-floor model is adopted for planting protogalaxies in simulated minihaloes. The model allocates gas quantities such as baryonic mass and temperature to every N -body particle and extensively exploits the particle nature of the data in the subsequent analysis. We have found that the number den...
