| Abstract: | This research project focuses on the emulation of the 21-cm signal of neutral hydrogen during the epoch of reionization, using a trained neural network to generate different signatures of this signal. The project employs the “globalemu” network (Bevins et al, 2021) which utilizes training of 10,000 signals generated from semi-numerical simulations to emulate the 21-cm signal. The primary objective of this research is to investigate variations in the astrophysical parameters within the neural network and their subsequent impacts on the emulated signal. A specific area of interest is establishing correlations between changes in these parameters and the occurrence of signal minima corresponding to the maximum signal amplitude. This research was conducted under the guidance of Dr. Saurabh Singh, Associate Professor at the Department of Astronomy and Astrophysics, Raman Research Institute, Bengaluru, India, starting from June 2023. |
