Rectifying No-Hair Theorems in Gauss-Bonnet theory
Alexandros Papageorgiou, Chan Park, Miok Park
We revisit the no-hair theorems in Einstein-Scalar-Gauss-Bonnet theory with a general coupling function between the scalar and the Gauss-Bonnet term in four dimensional spacetime.…
Small-scale shear: Peeling off diffuse subhalos with gravitational waves
Han Gil Choi, Chanung Park, Sunghoon Jung
Subhalos at subgalactic scales ( or ) are pristine test beds of dark matter (DM). However, they are too small, diffuse and d…
A Covariant Approach to 1+3 Formalism
Chan Park
I present a covariant approach to developing 1+3 formalism without an introduction of any basis or coordinates. In the formalism, a spacetime which has a timelike congruence is ass…
Open String Spectrum in pp-wave background
Chan Yong Park
In this paper, we consider the D-brane, especially -brane, in the pp-wave background, which has the eight dynamical and the eight kinematical supercharges. Since the pp-…
