On the stability of scalarized black hole solutions in scalar-Gauss-Bonnet gravity
Hector O. Silva, Caio F. B. Macedo, Thomas P. Sotiriou +3
Scalar-tensor theories of gravity where a new scalar degree of freedom couples to the Gauss-Bonnet invariant can exhibit the phenomenon of spontaneous black hole scalarization. The…
Oscillons in Higher-Derivative Effective Field Theories
Jeremy Sakstein, Mark Trodden
We investigate the existence and behavior of oscillons in theories in which higher derivative terms are present in the Lagrangian, such as galileons. Such theories have emerged in…
Splashback in galaxy clusters as a probe of cosmic expansion and gravity
Susmita Adhikari, Jeremy Sakstein, Bhuvnesh Jain +2
The splashback radius is a physical scale in dark matter halos that is set by the gravitational dynamics of recently accreted shells. We use analytical models and N-body simulation…
Superfluids and the Cosmological Constant Problem
Justin Khoury, Jeremy Sakstein, Adam R. Solomon
We introduce a novel method to circumvent Weinberg's no-go theorem for self-tuning the cosmological vacuum energy: a Lorentz-violating finite-temperature superfluid can counter the…
