Cosmic Transients, Einstein's Equivalence Principle and Dark Matter Halos
Orfeu Bertolami, Ricardo G. Landim
Cosmic transients, such as gamma-ray bursts and fast radio bursts, have been used to constrain the Einstein's Equivalence Principle (EEP) through the parametrized-post-Newtonian (P…
Quantum to classical transition in the Hořava-Lifshitz quantum cosmology
Alex E. Bernardini, Pedro Leal, Orfeu Bertolami
A quasi-Gaussian quantum superposition of Hořava-Lifshitz (HL) stationary states is built in order to describe the transition of the quantum cosmological problem to the related cla…
Collapsing Shells and Black Holes: a quantum analysis
P. Leal, A. E. Bernardini, O. Bertolami
The quantization of a spherically symmetric null shells is performed and extended to the framework of phase-space noncommutative (NC) quantum mechanics. The encountered properties…
Baryogenesis in Nonminimally Coupled Theories
M. P. L. P. Ramos, J. Páramos
We generalize the mechanism for gravitational baryogensis in the context of theories of gravity, including a nonminimal coupling between curvature and matter. In these model…
Gravitational waves in theories with a non-minimal curvature-matter coupling
Orfeu Bertolami, Cláudio Gomes, Francisco S. N. Lobo
Gravitational waves in the presence of a non-minimal curvature-matter coupling are analysed, both in the Newman-Penrose and perturbation theory formalisms. Considering a cosmologic…
Neutron Stars, Ungravity, and the I-Love-Q relation
Hodjat Mariji, Orfeu Bertolami
In this work, we study neutron stars (NSs) in an ungravity (UG) inspired model. We examine the UG effects on the static properties of the selected NSs, in different mass and radius…
Visible and Dark Matter Profiles in a Non-Minimally Coupled Model
Aníbal Silva, Jorge Páramos
A previous work found that a nonminimally coupled theory of gravity can, under appropriate conditions, give rise to an additional contribution to the field equations interpreted as…
Estimating the thermally induced acceleration of the New Horizons spacecraft
André G. C. Guerra, Frederico Francisco, Paulo J. S. Gil +1
Residual accelerations due to thermal effects are estimated through a model of the New Horizons spacecraft and a Monte Carlo simulation. We also discuss and estimate the thermal ef…
