Description
The next generation of ground-based gravitational wave detectors, such as the Einstein Telescope and Cosmic Explorer, will enable us to probe the cosmos in unprecedented ways. The design, location, and arm orientation of these detectors significantly influence their sensitivity and performance for various gravitational wave sources. For cosmological studies, the localization and distance measurement of compact binary coalescences, as well as the search for stochastic gravitational wave backgrounds are of particular interest. These targets, however, favor different detector configurations. We present a method to optimize the arm orientations within the detector network and demonstrate how to achieve a balanced configuration. Using Bayesian parameter estimation, we explicitly compare the detection, sky localization, and distance estimation capabilities for specific network configurations, focusing on binary neutron star coalescences.
