Strong Lensing Time Delay Constraints on Dark Energy: a Forecast
Banafshe Shiralilou, Matteo Martinelli, Georgios Papadomanolakis +3
Measurements of time delays between multiple quasar images produced by strong lensing are reaching a sensitivity that makes them a promising cosmological probe. Future surveys will…
The role of the tachyonic instability in Horndeski gravity
Noemi Frusciante, Georgios Papadomanolakis, Simone Peirone +1
The tachyonic instability is associated with the unboundedness of the Hamiltonian from below and results in an unstable low- regime. In the cosmological exploration of modified…
Tackling non-linearities with the effective field theory of dark energy and modified gravity
Noemi Frusciante, Georgios Papadomanolakis
We present the extension of the effective field theory framework to the mildly non-linear scales. The effective field theory approach has been successfully applied to the late time…
A de Sitter limit analysis for dark energy and modified gravity models
Antonio De Felice, Noemi Frusciante, Georgios Papadomanolakis
The effective field theory of dark energy and modified gravity is supposed to well describe, at low energies, the behaviour of the gravity modifications due to one extra scalar deg…
On the stability conditions for theories of modified gravity in presence of matter fields
Antonio De Felice, Noemi Frusciante, Georgios Papadomanolakis
We present a thorough stability analysis of modified gravity theories in the presence of matter fields. We use the Effective Field Theory framework for Dark Energy and Modified Gra…
