Description
LISAbeta tutorial
26 November 2025
In this tutorial, we introduce the package lisabeta, a simulator of data analysis for the future space-based gravitational wave detector LISA. Among LISA sources, Massive Black Hole Binaries (MBHBs) will open the possibility for multimessenger observations. We will present how to simulate the parameter estimation and in particular sky localization of MBHBs by LISA, for a merger as well as a pre-merger signal.
Agenda:
15:00-16:30 CET Introduction to LISA MBHBs with LISAbeta
John Baker and Sylvain Marsat
The first half of this session includes a presentation overviewing features of MBHB signals and how they are seen by LISA, providing an introduction to the subject and showcasing some of what LISAbeta can do. Then we will walk through a tutorial notebook which introduces shows how to work with LISA observations of MBHB signals in LISAbeta.
17:00-18:30 CET Example applications of LISAbeta to MBHB sky localization
Sylvain Marsat
In this session we will walk through some more specific applications of LISAbeta to explore how LISA locates MBHB system on the sky. Topics explore how well LISA locates MBHBs in advance of merger and the features of LISAs response which can resolve sky-location degeneracies. Analyses include localization estimates based on Fisher information and by Markov Chain Monte Carlo (MCMC).
