Fully relativistic predictions in Horndeski gravity from standard Newtonian N-body simulations
Guilherme Brando, Kazuya Koyama, David Wands +3
The N-body gauge allows the introduction of relativistic effects in Newtonian cosmological simulations. Here we extend this framework to general Horndeski gravity theories, and inv…
Gravitational wave lensing beyond general relativity: birefringence, echoes and shadows
Jose María Ezquiaga, Miguel Zumalacárregui
Gravitational waves (GW), as light, are gravitationally lensed by intervening matter, deflecting their trajectories, delaying their arrival and occasionally producing multiple imag…
Gravity in the Era of Equality: Towards solutions to the Hubble problem without fine-tuned initial conditions
Miguel Zumalacarregui
Discrepant measurements of the Universe's expansion rate () may signal physics beyond the standard cosmological model. Here I describe two early modified gravity mechanisms th…
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…
Theoretical priors in scalar-tensor cosmologies: Thawing quintessence
Carlos García-García, Emilio Bellini, Pedro G. Ferreira +2
The late time acceleration of the Universe can be characterized in terms of an extra, time dependent, component of the universe -- dark energy. The simplest proposal for dark energ…
hi_class: Background Evolution, Initial Conditions and Approximation Schemes
Emilio Bellini, Ignacy Sawicki, Miguel Zumalacárregui
Cosmological datasets have great potential to elucidate the nature of dark energy and test gravity on the largest scales available to observation. Theoretical predictions can be co…
