Primordial black holes and induced gravitational waves from inflation in the Horndeski theory of gravity
Pisin Chen, Seoktae Koh, Gansukh Tumurtushaa
We investigate the production of primordial black holes (PBHs) and scalar-induced gravitational waves (GWs) for cosmological models in the Horndeski theory of gravity. The cosmolog…
Observational Constraints on the Cosmology with Holographic Dark Fluid
Da Huang, Bum-Hoon Lee, Gansukh Tumurtushaa +2
We consider the holographic Friedman-Robertson-Walker (hFRW) universe on the 4-dimensional membrane embedded in the 5-dimensional bulk spacetime and fit the parameters with the obs…
Euclidean wormholes in Gauss-Bonnet-dilaton gravity
Xiao Yan Chew, Gansukh Tumurtushaa, Dong-han Yeom
We investigate Euclidean wormholes in Gauss-Bonnet-dilaton gravity to explain the creation of the universe from nothing. We considered two types of dilaton couplings (i.e., the str…
Constraints on dark energy models from the Horndeski theory
Bilguun Bayarsaikhan, Seoktae Koh, Enkhbat Tsedenbaljir +1
In light of the cosmological observations, we investigate dark energy models from the Horndeski theory of gravity. In particular, we consider cosmological models with the derivativ…
The viable f(G) gravity models via reconstruction from the observations
Seokcheon Lee, Gansukh Tumurtushaa
We reconstruct the viable f(G) gravity models from the observations and provide the analytic solutions that well describe our numerical results. In order to avoid unphysical challe…
Trans-Planckian censorship and single-field inflaton potential
Kenji Kadota, Chang Sub Shin, Takahiro Terada +1
It was recently proposed that a field theory cannot be consistent with quantum gravity if it allows a mode shorter than the Planck length to exit the Hubble horizon. This is called…
