Exotic compact objects in Einstein-scalar-Maxwell theories

Antonio De Felice, Shinji Tsujikawa

In k-essence theories within general relativity, where the matter Lagrangian depends on a real scalar field and its kinetic term , static and spherically symmetric compact o…

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…

Strong coupling and instabilities in singularity-free inflation from an infinite sum of curvature corrections

Shinji Tsujikawa

Four-dimensional gravitational theories derived from an infinite sum of Lovelock curvature invariants, combined with a conformal rescaling of the metric, are equivalent to a subcla…

Tidal Love Numbers of Neutron Stars in Horndeski Theories

Robin Fynn Diedrichs, Shinji Tsujikawa, Kent Yagi

Precision measurements of the gravitational wave signal from compact binary inspirals allow us to constrain the internal structure of those objects via physical parameters such as…
