(the new) LISA Data Challenges

...or, as we call them, the LDCs—an open, collaborative effort to tackle unsolved problems in LISA data analysis, while developing software tools that will form the basis of the future LISA data system.

The LDCs are organized by the LISA Consortium's LDC working group. Please join us as we write code and specifications to generate challenge datasets, and we work together to search for gravitational-wave sources and estimate their parameters. If you prefer to explore by yourself, develop your algorithms (or improve ours), then submit your methods and results so we can learn from them.

The LDCs are supported by the LISA LISA Data Processing Group (LDPG) at APC Paris.

Challenge 2a HM

Codenamed Sangria-HM and released on November 15, 2024, this challenge seeks to introduce new researchers to LISA data analysis, to rehabilitate existing analysis codes, and to establish our process and standards.

We expect to collect Challenge-2a-HM entries by March 1st, 2025.

LDC software

We periodically release all software developed by the working group to build and analyze datasets. Working-group members have read/write access to our code repository.

Coming soon: LDC tutorials and example codes.
