Hubble constant by natural selection: Evolution chips in the Hubble tension
Reginald Christian Bernardo, You-Ru Lee
The Approximate Bayesian Computation (ABC) algorithm considers natural selection in biology as a guiding principle for statistical model selection and parameter estimation. We take…
Dark energy by natural evolution: Constraining dark energy using Approximate Bayesian Computation
Reginald Christian Bernardo, Daniela Grandón, Jackson Levi Said +1
We look at dark energy from a biology inspired viewpoint by means of the Approximate Bayesian Computation (ABC) and late time cosmological observations. We find that dynamical dark…
Pulsar and cosmic variances of pulsar timing-array correlation measurements of the stochastic gravitational wave background
Reginald Christian Bernardo, Kin-Wang Ng
Pulsar timing-array correlation measurements offer an exciting opportunity to test the nature of gravity in the cosmologically novel nanohertz gravitational wave regime. The stocha…
Stochastic gravitational wave background phenomenology in a pulsar timing array
Reginald Christian Bernardo, Kin-Wang Ng
Pulsar timing offers an independent avenue to test general relativity and alternative gravity theories. This requires an understanding of how metric polarizations beyond the famili…
Quantum and higher curvature corrections to the anti-de Sitter black hole
Kristian Hauser A. Villegas, Reginald Christian Bernardo
Black holes exert quantum pressure coming from the nonlocal gravity correction. We investigate this nonlocal correction for black holes in anti-de Sitter (AdS) spacetime and its du…
Looking out for the Galileon in the nanohertz gravitational wave sky
Reginald Christian Bernardo, Kin-Wang Ng
We study the polarizations induced by the Galileon as a stochastic gravitational wave background in the cross correlated power in a pulsar timing array. Working within Galileon gra…
Tadpole Cosmology: Self Tuning Without Degeneracy
Stephen Appleby, Reginald Christian Bernardo
Degeneracy is a method to accommodate exact, low energy vacuum states in scalar-tensor gravitational models despite the presence of an arbitrarily large vacuum energy. However, thi…
Dressed black holes in the new tensor-vector-scalar theory
Reginald Christian Bernardo, Che-Yu Chen
As incarnations of gravity in its prime, black holes are arguably the best target for us to demystify gravity. Keeping in mind the prominent role black holes play in gravitational…
