Abstract

[en] This master thesis gives an overview of the PyCBC tools that are used in order to detect a gravitational wave event. Each tool used for the analysis is described in two complementary ways: a computing one, where the working of the PyCBC tools are investigated, and a theoretical one, where the mathematics and the physics behind the tools are explained. There is also a chapter dedicated to the study of the impact of some parameters on the analysis.

Some future perspectives are also studied: the possibility to detect the gravitational waves early on, before the merger happens. We show that it is possible to detect the event based on only a part of it. We also considered overlapping signals: two binary black holes, one binary black hole and one binary neutron star, two binary neutron stars. It was shown that matched filtering is still very likely to work. In order to show this, new methods have been developed, which could be used in future analyses.
