Projected Constraints on Einstein-dilaton-Gauss-Bonnet Gravity with NICER Observations
ORAL
Abstract
Due to unprecedented resolution of the Neutron Star Interior Composition Explorer (NICER), we can detect X-rays emitted from hot spots on the surface of certain neutron stars, and extract vital information, helping us understand what happens to matter when nuclear saturation density is exceeded. Besides the interior of neutron stars, we can also use NICER data to constrain parameters of modified theories of gravity, and determine how close to Nature the predictions of GR are. In this talk, I will explain how we can use Bayesian techniques to strongly constrain Einstein-dilaton-Gauss-Bonnet gravity to a degree comparable to other gravitational wave constraints.
