CDM cosmology from a type-II minimally modified gravity
Ãzgür Akarsu, Antonio De Felice, Eleonora Di Valentino +5
We integrate CDM, a promising scenario for alleviating cosmological tensions, into VCDM, a type-II minimally modified gravity. This promotes the scenario to a fully pre…
Nonsingular black holes and spherically symmetric objects in nonlinear electrodynamics with a scalar field
Antonio De Felice, Shinji Tsujikawa
In general relativity with vector and scalar fields given by the Lagrangian , where is a Maxwell term and is a kinetic term of the scalar field , we s…
The non-minimal 3-form cosmology and the rise of the cuscuton
Antonio De Felice, Anamaria Hell
We consider the 3-form theory with non-minimal coupling to gravity in an expanding Universe. First, we assume that the background is homogeneous and isotropic, and that the three-f…
Unexplored regions in teleparallel gravity: Sign-changing dark energy density
Ozgur Akarsu, Bilal Bulduk, Antonio De Felice +2
While gravity has shown considerable potential in addressing cosmological tensions, we explore previously overlooked solution spaces that hold further promise. We examine th…
Instability of regular planar black holes in four dimensions arising from an infinite sum of curvature corrections
Antonio De Felice, Shinji Tsujikawa
In four-dimensional scalar-tensor theories derived via dimensional regularization with a conformal rescaling of the metric, we study the stability of planar black holes (BHs) whose…
Greybody factors of charged black holes with axion hair
Ratchaphat Nakarachinda, Petarpa Boonserm, Antonio De Felice +2
We study the greybody factor of charged hairy black holes (BHs) that arise due to the presence of an axion coupled to the electromagnetic field. Specifically, we consider spin-0 an…
