Physics of Cosmic Reionization
The study of cosmic reionization has acquired increasing significance over the last few years because of various reasons. On the observational front, we now have good quality data of different types at high redshifts (quasar absorption spectra, radiation backgrounds at different frequencies, cosmic microwave background polarization, Lyα emitters and so on). Theoretically, the importance of the ...
متن کاملRadiative Transfer Simulations of Cosmic Reionization I: Methodology and Initial Results
We present a new hybrid code for large volume, high resolution simulations of cosmic reionization, which utilizes a N-body algorithm for dark matter, physically motivated prescriptions for baryons and star formation, and an adaptive ray tracing algorithm for radiative transfer of ionizing photons. Two test simulations each with 3 billion particles and 400 million rays in a 50 Mpc/h box have bee...
متن کاملThe Kinetic Sunyaev-zel’dovich Effect from Radiative Transfer Simulations of Patchy Reionization
We present the first calculation of the kinetic Sunyaev-Zel’dovich (kSZ) effect due to the inhomogeneous reionization of the universe based on detailed large-scale radiative transfer simulations of reionization. The resulting sky power spectra peak at l = 2000 − 8000 with maximum values of [l(l + 1)Cl/(2π)]max ∼ 1 × 10 . The peak scale is determined by the typical size of the ionized regions an...
متن کاملUsing Neural Network to Control STATCOM for ImprovingTransient Stability
FACTS technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is oneof the most important FACTS devices used in the parallel compensation, enhancing transient stability andetc. Since three phase fault is widespread in power systems, in this paper STATCOM is used...
متن کاملCosmic Reionization and the 21cm Signal: Simulations and Analytical Models
We measure several properties of the reionization process and the corresponding low-frequency 21-cm signal associated with the neutral hydrogen distribution, using a large volume, high resolution simulation of cosmic reionization. The simulation involving 24 billion dark matter particles utilizes a hybrid code with a particle-mesh N-body algorithm for dark matter and prescriptions for baryons a...
