Measuring dark energy with expansion and growth
Louis Perenon, Matteo Martinelli, Roy Maartens +2
We combine cosmic chronometer and growth of structure data to derive the redshift evolution of the dark energy equation of state , using a novel agnostic approach. The backgroun…
Constraining spatial curvature with large-scale structure
Julien Bel, Julien Larena, Roy Maartens +2
We analyse the clustering of matter on large scales in an extension of the concordance model that allows for spatial curvature. We develop a consistent approach to curvature and wi…
Multi-tasking the growth of cosmological structures
Louis Perenon, Matteo Martinelli, Stéphane Ilić +3
Next-generation large-scale structure surveys will deliver a significant increase in the precision of growth data, allowing us to use `agnostic' methods to study the evolution of p…
Improvements in cosmological constraints from breaking growth degeneracy
Louis Perenon, Stéphane Ilić, Roy Maartens +1
The key probes of the growth of large-scale structure are its rate and amplitude . Redshift space distortions in the galaxy power spectrum allow us to measure only the com…
Effective Field Theory of Dark Energy: a Review
Noemi Frusciante, Louis Perenon
The discovery of cosmic acceleration has triggered a consistent body of theoretical work aimed at modeling its phenomenology and understanding its fundamental physical nature. In r…
The effective field theory of dark energy diagnostic of linear Horndeski theories after GW170817 and GRB170817A
Louis Perenon, Hermano Velten
We summarise the effective field theory of dark energy construction to explore observable predictions of linear Horndeski theories. Based on \cite{Perenon:2016blf}, we review the d…
Optimising growth of structure constraints on modified gravity
Louis Perenon, Julien Bel, Roy Maartens +1
We use growth of structure data to constrain the effective field theory of dark energy. Considering as case study Horndeski theories with the speed of gravitational waves equal to…
Diagnostic of Horndeski Theories
Louis Perenon, Christian Marinoni, Federico Piazza
We study the effects of Horndeski models of dark energy on the observables of the large-scale structure in the late time universe. A novel classification into {\it Late dark energy…
General features of single-scalar field dark energy models
Louis Perenon
We present a systematic study of modified gravity (MG) models containing a single scalar field non-minimally coupled to the metric. Despite a large parameter space, exploiting the…
Phenomenology of dark energy: general features of large-scale perturbations
Louis Perenon, Federico Piazza, Christian Marinoni +1
We present a systematic exploration of dark energy and modified gravity models containing a single scalar field non-minimally coupled to the metric. Even though the parameter space…
