Onset of spontaneous scalarization in generalized scalar-tensor theories (2020)
Journal Article
Ventagli, G., Lehébel, A., & Sotiriou, T. P. (2020). Onset of spontaneous scalarization in generalized scalar-tensor theories. Physical Review D, 102(2), Article 024050. https://doi.org/10.1103/PhysRevD.102.024050

In gravity theories that exhibit spontaneous scalarization, astrophysical objects are identical to their general relativistic counterpart until they reach a certain threshold in compactness or curvature. Beyond this threshold, they acquire a nontrivi... Read More about Onset of spontaneous scalarization in generalized scalar-tensor theories.

Black holes in self-tuning cubic Horndeski cosmology (2020)
Journal Article
Emond, W. T., Lehébel, A., & Saffin, P. M. (2020). Black holes in self-tuning cubic Horndeski cosmology. Physical Review D, 101(8), Article 084008. https://doi.org/10.1103/physrevd.101.084008

Observations of neutron star mergers in the late Universe have given significant restrictions to the class of viable scalar-tensor theories. In this paper we construct black holes within the “self-tuning” class of this restricted set, whereby the bar... Read More about Black holes in self-tuning cubic Horndeski cosmology.
