Instability of Black Holes with a Gauss-Bonnet Term
Wha-Keun Ahn, Bogeun Gwak, Bum-Hoon Lee +1
We investigate the fragmentation instability of hairy black holes in the theory with a GaussBonnet(GB) term in asymptotically flat spacetime. Our approach is through the non-per…
Gravitational waves from cosmic bubble collisions
Dong-Hoon Kim, Bum-Hoon Lee, Wonwoo Lee +2
Cosmic bubbles are nucleated through the quantum tunneling process. After nucleation they would expand and undergo collisions with each other. In this paper, we focus in particular…
Observational constraints on slow-roll inflation coupled to a Gauss-Bonnet term
Seoktae Koh, Bum-Hoon Lee, Wonwoo Lee +1
We study slow-roll inflation with a Gauss-Bonnet term that is coupled to an inflaton field nonminimally. We investigate the inflationary solutions for a specific type of the nonmin…
