Wormhole geometries induced by action-dependent Lagrangian theories
Ismael Ayuso, Francisco S. N. Lobo, José P. Mimoso
In this work, we explore wormhole geometries in a recently proposed modified gravity theory arising from a non-conservative gravitational theory, tentatively denoted action-depende…
Observational constraints on cosmological solutions of theories
Ismael Ayuso, Ruth Lazkoz, Vincenzo Salzano
Over the last years some interest has been gathered by theories, which are new candidates to replace Einstein's prescription for gravity. The non-metricity tensor allows…
Extremal cosmological black holes in Horndeski gravity and the anti-evaporation regime
Ismael Ayuso, Diego Sáez-Chillón Gómez
Extremal cosmological black holes are analysed in the framework of the most general second order scalar-tensor theory, the~so-called Horndeski gravity. Such~extremal black holes ar…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
What if Newton's Gravitational Constant was negative?
Ismael Ayuso, José P. Mimoso, Nelson J. Nunes
In this work, we seek a cosmological mechanism that may define the sign of the effective gravitational coupling constant, {\em G}. To this end, we consider general scalar-tensor gr…
