The multi - frequency angular power spectrum of the epoch of reionization 21 cm signal
Observations of redshifted 21cm radiation from neutral hydrogen (HI) at high redshifts is an important future probe of reionization. We consider the Multi-frequency Angular Power Spectrum (MAPS) to quantify the statistics of the HI signal as a joint function of the angular multipole l and frequency separation ∆ν. The signal at two different frequencies is expected to get decorrelated as ∆ν is i...
متن کاملThe Structure of Cosmic String Wakes
The clustering of baryons and cold dark matter induced by a single moving string is analyzed numerically, making use of the new three-dimensional Eulerian cosmological hydrocode of Sornborger et al., which uses the piecewise parabolic method to track the baryons and the particle-in-cell method to evolve the dark matter particles. A long straight string moving with a speed comparable to c induce...
متن کاملLight-cone effect on the reionization 21-cm power spectrum
Observations of redshifted 21-cm radiation from neutral hydrogen during the epoch of reionization are considered to constitute the most promising tool to probe that epoch. One of the major goals of the first generation of low-frequency radio telescopes is to measure the 3D 21-cm power spectrum. However, the 21-cm signal could evolve substantially along the lineof-sight (LOS) direction of an obs...
متن کاملCosmic string formation and the power spectrum of field configurations.
We examine the statistical properties of defects formed by the breaking of a U(1) symmetry when the Higgs field has a power spectrum P (k) ∝ kn. We find a marked dependence of the amount of infinite string on the spectral index n and empirically identify an analytic form for this quantity. We also confirm that this result is robust to changes in the definition of infinite string. It is possible...
متن کاملDegree Angular Scale Interferometer First Results: a Measurement of the Cosmic Microwave Background Angular Power Spectrum
We present measurements of anisotropy in the cosmic microwave background (CMB) from the first season of observations with the Degree Angular Scale Interferometer (DASI). The instrument was deployed at the South Pole in the austral summer 1999–2000, and we made observations throughout the following austral winter. We present a measurement of the CMB angular power spectrum in the range 100 < l < ...
