Theoretical filters for shift-symmetric Horndeski gravities
Athanasios Bakopoulos, Christos Charmousis, Nikos Chatzifotis +1
We investigate the structure of nontrivial maximally symmetric vacua and compact-object solutions in shift-symmetric scalar-tensor theories. Focusing on Horndeski gravity, we deriv…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Thermodynamic analysis of shift-symmetric black-hole spacetimes in Horndeski gravity
Athanasios Bakopoulos, Thanasis Karakasis
In this study, we investigate the thermodynamic properties of shift symmetric Horndeski and beyond Horndeski theories (theories in which only derivatives of the scalar field appear…
To stealth or not to stealth: Thermodynamics of stealth black holes
Athanasios Bakopoulos, Thanasis Karakasis, Eleftherios Papantonopoulos
Using Euclidean methods we investigate the thermodynamics of stealth black hole solutions, which are solutions that geometrically are indistinguishable from those of general relati…
Thermodynamics of black holes featuring primary scalar hair
Athanasios Bakopoulos, Nikos Chatzifotis, Thanasis Karakasis
In this work, we embark on the thermodynamic investigation concerning a family of primary charged black holes within the context of shift and parity symmetric Beyond Horndeski grav…
Exact black holes in string-inspired Euler-Heisenberg theory
Athanasios Bakopoulos, Thanasis Karakasis, Nick E. Mavromatos +2
We consider higher-order derivative gauge field corrections that arise in the fundamental context of dimensional reduction of String Theory and Lovelock-inspired gravities and obta…
