Detectability and Parameter Estimation for Einstein Telescope Configurations with GWJulia

Understand

Future gravitational-wave (GW) detectors are expected to detect tens of thousands of compact binary coalescences (CBC) per year, depending also on the final detectors layout.

• For this reason, it is essential to have a fast, reliable tool for forecasting how different detector layouts will affect parameter estimation for these events.
• The Fisher Information Matrix (FIM) is a common tool for tackling this problem.
• In this paper, we present a new open source code GWJulia to perform FIM analysis of CBC parameters, i.e., stellar black-hole binaries (BBH), neutron star binaries (BNS), and neutron star-black hole binaries (NSBH).
