| This is the 4th LISA Cosmology Working Group Workshop. After the selection of the LISA mission by ESA following the call for mission in autumn 2016, and the end of ESA design study in summer 2017, the configuration of the LISA interferometer is substantially fixed. It is therefore time to precisely assess the capability of the new LISA configuration to test different aspects of cosmology and fundamental physics. Moreover, the community must start to dwell on new issues connected with data analysis techniques and with the needs of the LISA Consortium to address ESA requests. The goal of the present workshop is to obtain concrete results in this respect, therefore, it will be dedicated mostly to collaborative work in teams, accompanied by a few seminars on new results. |  |
The workshop will cover the following main topics:
- First order phase transitions
- Detection of stochastic backgrounds
- Topological defects
- Standard sirens
- Testing General Relativity
- Inflation and beyond
- Primordial black holes and dark matter
- Structure formation
