Detection of Massive Black Holes with Gravitational Lensing Effects on Light Curves of Gamma-Ray Bursts Observed by Fermi Telescope, Ph.D. Dissertation Sharif University of Technology ; Rahvar, Sohrab (Supervisor) ; Rahimi Tabar, Mohammad Reza (Co-Supervisor)
Abstract
In this thesis, we investigate the imprint of gravitational microlensing effects on the light curves of Gamma-ray burst (GRBs) to estimate compact object mass in the form of black holes in the Universe. We assume a point mass model of the gravitational lens and a geometry in which the source−lens are at the same direction that manifests in the GRB light curve as superimposed peaks by the time delay between the two images and searches the Fermi/GBM catalog. According to the sensitivity of our detection method, we consider microlensing events with a time delay on the order of 10 s due to point-mass lenses in the range of 〖10〗^5- 〖10〗^7 M_(⊙ ). We found one microlensed GRB candidate out of...
