Higgs-Portal Stueckelberg Dark Matter
Antonio De Felice, Takehiro Ogura, Shinji Tsujikawa +1
We study dark photon dark matter associated with a dark gauge symmetry. To evade laboratory and cosmological constraints on kinetic mixing with the Standard Model $U(1…
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…
Vector Horndeski black holes in nonlinear electrodynamics
Che-Yu Chen, Antonio De Felice, Shinji Tsujikawa +1
On a spherically symmetric and static background, we study the existence of linearly stable black hole (BH) solutions in nonlinear electrodynamics (NED) with a Horndeski vector-ten…
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…
Challenging CDM: 5 Evidence for a Dynamical Dark Energy Late-Time Transition
Mateus Scherer, Miguel A. Sabogal, Rafael C. Nunes +1
Recently, there has been considerable debate regarding potential evidence for the dynamical nature of dark energy (DE), particularly in light of Baryon Acoustic Oscillations (BAO)…
