Journal ArticleDOI
Disformal gravity theories: a Jordan frame analysis
Jeremy Sakstein,Sarunas Verner +1 more
TL;DR: In this article, the Friedmann equations were used to study the late-time cosmology using dynamical systems methods and by finding approximate solutions to find approximate de-Sitter solutions for general disformal theories.
Journal ArticleDOI
Novel Probes Project: Tests of gravity on astrophysical scales
Tessa Baker,Alexandre Barreira,Harry Desmond,Pedro G. Ferreira,Bhuvnesh Jain,Kazuya Koyama,Baojiu Li,Lucas Lombriser,Andrina Nicola,Jeremy Sakstein,Fabian Schmidt +10 more
TL;DR: In this article, a survey of the constraints on modified-gravity models using astrophysical objects in the cosmological, weak-field regime is presented, embedded in the framework of the novel probes project, a forum connecting observers and theorists involved in the study of dark sector interactions.
Journal ArticleDOI
Beyond the Standard Model Explanations of GW190521.
TL;DR: Several explanations based on models of new physics, including new light particle losses, modified gravity, large extra dimensions, and a small magnetic moment of the neutrino are proposed for the detection of a heavy binary black hole merger in LIGO-Virgo.
Journal ArticleDOI
Tests of Gravity with Future Space-Based Experiments
TL;DR: In this paper, the authors estimate the bounds that could be obtained on alternative gravity theories that use screening mechanisms to suppress deviations from general relativity in the Solar System: chameleon, symmetron, and Galileon models.
Journal ArticleDOI
Tests of Chameleon Gravity
Clare Burrage,Jeremy Sakstein +1 more
TL;DR: The present state-of-the-art searches for screened scalars coupled to matter are summarized, and the current bounds on f(R) models that exhibit the chameleon mechanism are translated into a single parametrization to survey the state of the models.
