Title of your presentation : Simulation of 21(1+z) cm EoR signal for LOFAR

The sensitive dependence of the history of reionization on numerous factors including the types of sources (stars/qsos) and their spectra, clustering properties, lifetimes and so on., urges us to recreate as many scenarios for reionization as possible. It is also imperative that each of these models do flow through the LOFAR pipeline of the instrumental response and signal retrival to establish a working mode and algorithm for the LOFAR-EoR experiment. Given the computational expenses of a full 3D radiative transfer code, it becomes impossible to test all the given scenarios. Therefore, we have developed a semi-analytical model in which any given N-body simulation is coupled to a 1-D radiative transfer code to mimic various reionization scenarios. We will present the basic LOFAR-EoR pipeline and the algorithm mentioned.
