Compact objects with primary hair in shift and parity symmetric beyond Horndeski gravities
Athanasios Bakopoulos, Nikos Chatzifotis, Theodoros Nakas
In this work, we delve into the model of the shift symmetric and parity-preserving Beyond Horndeski theory in all its generality. We present an explicit algorithm to extract static…
Black holes with primary scalar hair
Athanasios Bakopoulos, Christos Charmousis, Panagiota Kanti +2
We present explicit black holes endowed with primary scalar hair within the shift-symmetric subclass of Beyond Horndeski theories. These solutions depend, in addition to the conven…
Bridging Dimensions: General Embedding Algorithm and Field-Theory Reconstruction in 5D Braneworld Models
Theodoros Nakas, Thomas D. Pappas, Zdeněk Stuchlík
We develop a general algorithm that enables the consistent embedding of any four-dimensional static and spherically symmetric geometry into any five-dimensional single-brane branew…
Novel exact ultra-compact and ultra-sparse hairy black holes emanating from regular and phantom scalar fields
Athanasios Bakopoulos, Theodoros Nakas
In the framework of a simple gravitational theory that contains a scalar field minimally coupled to gravity, we investigate the emergence of analytic black-hole solutions with non-…
