Do equation of state parametrizations of dark energy faithfully capture the dynamics of the late universe?
Özgür Akarsu, Maria Caruana, Konstantinos F. Dialektopoulos +3
We investigate how strongly late-time inferences about DE dynamics depend on the functional prior used to represent the expansion history. Using identical late-time combinations of…
Hints of sign-changing scalar field energy density and a transient acceleration phase at from model-agnostic reconstructions
Özgür Akarsu, Maria Caruana, Konstantinos F. Dialektopoulos +3
We present a data-driven reconstruction of the late-time expansion history and its implications for dark-energy dynamics. Modeling the reduced Hubble rate with a node-based Gaussia…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Gauge invariant perturbations in teleparallel Horndeski gravity
Bobomurat Ahmedov, Maria Caruana, Jackson Levi Said +4
We present in the form of a catalogue of the cosmological perturbations within the Bahamonde- Dialektopoulos-Levi Said (BDLS) theory, which serves as the teleparallel counterpart o…
Spatial Dependence of the Growth Factor in Scalar-Tensor Cosmology
Maria Caruana, Gabriel Farrugia, Jackson Levi Said +1
Scalar-tensor theories have taken on a key role in attempts to confront the growing open questions in standard cosmology. It is important to understand entirely their dynamics at p…
Cosmic Growth in Teleparallel Gravity
Salvatore Capozziello, Maria Caruana, Gabriel Farrugia +2
Physical evolution of cosmological models can be tested by using expansion data, while growth history of these models is capable of testing dynamics of the inhomogeneous parts of e…
Ghost and Laplacian Instabilities in the Teleparallel Horndeski Gravity
Salvatore Capozziello, Maria Caruana, Jackson Levi Said +1
Teleparallel geometry offers a platform on which to build up theories of gravity where torsion rather than curvature mediates gravitational interaction. The teleparallel analogue o…
Well-Tempered Minkowski Solutions in Teleparallel Horndeski Theory
Reginald Christian Bernardo, Jackson Levi Said, Maria Caruana +1
Well-tempering stands among the few classical methods of screening vacuum energy to deliver a late-time, low energy vacuum state. We build on the class of Horndeski models that adm…
Well-tempered teleparallel Horndeski cosmology: a teleparallel variation to the cosmological constant problem
Reginald Christian Bernardo, Jackson Levi Said, Maria Caruana +1
Well-tempering is a promising classical method of dynamically screening an arbitrarily large vacuum energy and generating a late-time, low energy de Sitter vacuum state. In this pa…
Gravitational Wave Propagation and Polarizations in the Teleparallel analog of Horndeski Gravity
Sebastian Bahamonde, Maria Caruana, Konstantinos F. Dialektopoulos +5
Gravitational waves (GWs) have opened a new window on fundamental physics in a number of important ways. The next generation of GW detectors may reveal more information about the p…
Cosmological bouncing solutions in f(T,B) gravity
Maria Caruana, Gabriel Farrugia, Jackson Levi Said
Teleparallel Gravity offers the possibility of reformulating gravity in terms of torsion by exchanging the Levi-Civita connection with the Weitzenböck connection which describes to…
