Chromatic effects in the 21 cm global signal from the cosmic dawn
The redshifted 21 cm brightness distribution from neutral hydrogen is a promising probe into the cosmic dark ages, cosmic dawn, and re-ionization. LOFAR’s Low Band Antennas (LBA) may be used in the frequency range 45 MHz to 85 MHz (30 > z > 16) to measure the sky averaged redshifted 21 cm brightness temperature as a function of frequency, or equivalently, cosmic redshift. These low frequencies ...
متن کاملStatistics of Peculiar Velocities from Cosmic Strings
We calculate the probability distribution of a single component of peculiar velocities due to cosmic strings, smoothed over regions with a radius of several h 1 Mpc. The probability distribution is shown to be Gaussian to good accuracy, in agreement with the distribution of peculiar velocities deduced from the 1.9 Jy IRAS redshift survey. Using the normalization of parameters of the cosmic stri...
متن کاملCosmic 21-cm Fluctuations as a Probe of Fundamental Physics
Fluctuations in high-redshift cosmic 21-cm radiation provide a new window for observing unconventional effects of high-energy physics in the primordial spectrum of density perturbations. In scenarios for which the initial state prior to inflation is modified at short distances, or for which deviations from scale invariance arise during the course of inflation, the cosmic 21-cm power spectrum ca...
متن کاملStudying the sources of cosmic reionization with 21-cm fluctuations
We explore the ability of measurements of the 21-cm power spectrum during reionization to enable the simultaneous reconstruction of the reionization history and the properties of the ionizing sources. For various sets of simulated 21-cm measurements, we perform maximum likelihood fits in order to constrain the reionization and galaxy formation histories. We employ a flexible six-parameter model...
متن کاملPeculiar Velocities and Microwave Background Anisotropies from Cosmic Strings
Using an analytic model we show that the predictions of the cosmic string model for the peculiar velocities and the microwave background (MBR) anisotropy depend on similar combinations of string evolution parameters. Normalizing from the COBE detection of MBR anisotropy, and for certain reasonable values of string network evolution parameters, we find that the magnitude of predicted velocity fl...
