General theories of linear gravitational perturbations to a Schwarzschild Black Hole
Oliver J. Tattersall, Pedro G. Ferreira, Macarena Lagos
We use the covariant formulation proposed in Tattersall et al (2017) to analyse the structure of linear perturbations about a spherically symmetric background in different families…

A covariant approach to parameterised cosmological perturbations
Oliver J. Tattersall, Macarena Lagos, Pedro G. Ferreira
We present a covariant formulation for constructing general quadratic actions for cosmological perturbations, invariant under a given set of gauge symmetries for a given field cont…
