Journal ArticleDOI
Implications of the Neutron Star Merger GW170817 for Cosmological Scalar-Tensor Theories
Jeremy Sakstein,Bhuvnesh Jain +1 more
TL;DR: Three of the five parameters appearing in the effective theory of dark energy can now be severely constrained on astrophysical scales; the results of combining the new gravity wave results with galaxy cluster observations are presented.
Journal ArticleDOI
Spontaneous Scalarization of Black Holes and Compact Stars from a Gauss-Bonnet Coupling
Hector O. Silva,Hector O. Silva,Jeremy Sakstein,Leonardo Gualtieri,Thomas P. Sotiriou,Emanuele Berti +5 more
TL;DR: A class of scalar-tensor theories with coupling between the scalar and the Gauss-Bonnet invariant that exhibit spontaneous scalarization for both black holes and compact stars are identified.
Journal ArticleDOI

Solomon,Douglas Spolyar,Glenn D. Starkman,Daniele A. Steer,Ismael Tereno,L. Verde,Francisco Villaescusa-Navarro,Mikael von Strauss,Hans A. Winther +41 more
TL;DR: There is a persistent interest in extending cosmology beyond the standard model, ΛCDM, motivated by a range of apparently serious theoretical issues, involving such questions as the cosmological constant problem, the particle nature of dark matter, the validity of general relativity on large scales, the existence of anomalies in the CMB and on small scales, and the predictivity and testability of the inflationary paradigm as mentioned in this paper.

TL;DR: There is a persistent interest in extending cosmology beyond the standard model, $\Lambda$CDM as discussed by the authors, motivated by a range of apparently serious theoretical issues, involving such questions as the cosmological constant problem, the particle nature of dark matter, the validity of general relativity on large scales, the existence of anomalies in the CMB and on small scales, and the predictivity and testability of the inflationary paradigm.
Journal ArticleDOI
Tests of chameleon gravity
Clare Burrage,Jeremy Sakstein +1 more
TL;DR: A review of the state-of-the-art searches for screened scalars coupled to matter can be found in this article, where the authors summarize the results of these searches and discuss the future prospects for constraining screened modified gravity models further using upcoming and planned experiments.
