Towards a model-independent reconstruction approach for late-time Hubble data
Reginald Christian Bernardo, Jackson Levi Said
Gaussian processes offers a convenient way to perform nonparametric reconstructions of observational data assuming only a kernel which describes the covariance between neighbouring…
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…
A data-driven Reconstruction of Horndeski gravity via the Gaussian processes
Reginald Christian Bernardo, Jackson Levi Said
We reconstruct the Hubble function from cosmic chronometers, supernovae, and baryon acoustic oscillations compiled data sets via the Gaussian process (GP) method and use it to draw…
Gravitational wave signatures from dark sector interactions
Reginald Christian Bernardo
We show that the gravitational waves generated by the perturbations of general relativistic black holes can be considered as a direct probe of the existence of dark sector interact…
Self-tuning kinetic gravity braiding: Cosmological dynamics, shift symmetry, and the tadpole
Reginald Christian Bernardo
We study the self-tuning subclass of kinetic gravity braiding and obtain robust predictions on self-tuning and dynamics in the tadpole-free shift symmetric sector of the theory. In…
Stealth black holes in shift symmetric kinetic gravity braiding
Reginald Christian Bernardo, John Celestial, Ian Vega
We derive all hairy stealth black holes in the most general second-order, shift symmetric, scalar-tensor theory with luminally propagating gravitational waves, often called kinetic…
