The sound of dynamical dark energy and modified gravity
João Rebouças, Guilherme Brando, Felipe T. Falciano +1
Different candidate models are able to reproduce the dynamical dark energy signal preferred by combinations of recent distance measurements. These models may be distinguished by th…
Testing inflation on all scales: a case study with -attractors
Laura Iacconi, Michael Bacchi, Luiz Filipe Guimarães +1
A plethora of inflationary models can produce interesting small-scale phenomenology, such as enhanced scalar fluctuations leading to primordial black hole (PBH) production and larg…
Modeling nonlinear scales with COLA: preparing for LSST-Y1
Jonathan Gordon, Bernardo F. de Aguiar, João Rebouças +5
Year 1 results of the Legacy Survey of Space and Time (LSST) will provide tighter constraints on small-scale cosmology, beyond the validity of linear perturbation theory. This heig…
Neutron stars in the symmetron model
Bernardo F. de Aguiar, Raissa F. P. Mendes, F. T. Falciano
Screening mechanisms are often deployed by dark energy models in order to conceal the effects of their new degrees of freedom from the scrutiny of terrestrial and solar system expe…
Entropy bound in Einstein-Born-Infeld black holes
F. T. Falciano, M. L. Peñafiel, J. C. Fabris
We study the validity of Bekenstein's entropy bound for a charged black hole in the context of nonlinear electrodynamics. Bekenstein's inequalities are commonly understood as unive…
Viable Curvaton Models from the Parameter
L. F. Guimarães, F. T. Falciano
We show how to build a curvaton inflationary model motivated by scale-dependent non-Gaussianities of cosmological perturbations. In particular, we study the change of sign in the $…
