Contribution

It provides an overview of the first MLDC, including challenge design, participant results, and a critical assessment of the data analysis capabilities demonstrated.

Findings

Multiple groups successfully identified simulated signals.

The challenges highlighted strengths and areas for improvement in analysis methods.

Community engagement demonstrated readiness for real LISA data analysis.

Abstract

The Mock LISA Data Challenges (MLDCs) have the dual purpose of fostering the development of LISA data analysis tools and capabilities, and demonstrating the technical readiness already achieved by the gravitational-wave community in distilling a rich science payoff from the LISA data output. The first round of MLDCs has just been completed: nine data sets containing simulated gravitational wave signals produced either by galactic binaries or massive black hole binaries embedded in simulated LISA instrumental noise were released in June 2006 with deadline for submission of results at the beginning of December 2006. Ten groups have participated in this first round of challenges. Here we describe the challenges, summarise the results, and provide a first critical assessment of the entries.
