The Cosmology Group is involved in the LISA Consortium: Michele Maggiore and Stefano Foffa as Full Members, Enis Belgacem, Camille Bonvin, Charles Dalang, Ruth Durrer, Martin Kunz and Lucas Lombriser as Associate Members. Valerio De Luca, Gabriele Franciolini and Toni Riotto are also part of the Consortium in association with the INFN Padua group.
Our contribution to LISA concerns theoretical studies of the implications of LISA for dark energy, dark matter, modified gravity, and cosmology in general. In particular: use of standard sirens to study the imprint of dark energy on GW propagation (Dalang, Lombriser; Belgacem, Foffa, Maggiore) use of standard sirens for cosmological parameter estimations (Belgacem, Foffa, Kunz, Maggiore), effects of gravitational lensing and matter inhomegeneities on the luminosity distance (Bonvin,Durrer), studies of primordial black holes as dark matter candidates and non-Gaussian gravitational wave signals (De Luca, Franciolini, Riotto).
