Testing gravitational wave polarizations with LISA
Shingo Akama, Maxence Corman, Paola C. M. Delgado +16
In this paper we quantify the ability of the Laser Interferometer Space Antenna (LISA) to test the presence of non-tensorial polarizations as well as modifications to the tensor on…

Multiple-scale analysis of modified gravitational-wave propagation
Marco de Cesare, Mairi Sakellariadou, Benjamin Sutton
We employ multiple-scale analysis to systematically derive analytical approximations describing the cosmological propagation of gravitational waves beyond general relativity, in a…

Analytical constraints on gravitational models with a quadratic Weyl tensor
Benjamin Sutton, Antonio de Felice, Mairi Sakellariadou
We set analytical constraints on the parameter space of models of gravity containing a term quadratic in Weyl curvature . In this class of models, there are four propagatin…
