The goal of the CosWG is to investigate the scientific return of LISA related to cosmology. The CosWG also studies the science that can be analysed by cross-correlating LISA measurements with cosmological observables or robust, cosmological theories.

The activity of the CosWG is carried out by sharing knowledge, resources, and ideas in a joint effort among any CosWG member willing to contribute to a particular CosWG project. All projects that are proposed to the CosWG and accepted as CosWG projects, become CosWG ideas whose development is a collegial task.

Examples of past or ongoing CosWG projects:

Projects developed in synergy with the other LISA working groups are foreseen.

LISA CosWG identification number

The LISA Consortium assigns an identification number to the CosWG papers that satisfy a high standard, are developed collegialy, and are tightly connected to the LISA workpackages and science.

The author list is in two tiers, each one in alphabetical order. The first tier includes who provided important contributions, while second tier includes who provided less important but still significant contribution. The author list also highlights the coordinator(s) of the article, i.e. who led the project and organized the project team, and the correspoding author(s), i.e. who contributed most to the article in terms of time and concrete results.

Exception is the white paper where first tier includes who contributed to the article, and second tier who endorses the article.

The exhaustive and updated list of these articles is the following:
