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.
