Gravitational Waves from Hierarchical Triple Systems with Kozai-Lidov Oscillation

Priti Gupta, Haruka Suzuki, Hirotada Okawa +1

We study gravitational waves from a hierarchical three-body system up to first-order postNewtonian approximation. Under certain conditions, the existence of a nearby third body can…

Maximal Efficiency of Collisional Penrose Process with Spinning Particle II

Kazumasa Okabayashi, Kei-ichi Maeda

We analyze the collisional Penrose process between a particle on the ISCO orbit around an extreme Kerr black hole and a particle impinging from infinity. We consider both cases wit…

Cumulative Shift of Periastron Time of Binary Pulsar with Kozai-Lidov Oscillation

Haruka Suzuki, Priti Gupta, Hirotada Okawa +1

We study a hierarchical triple system with the Kozai-Lidov mechanism, and analyse the cumulative shift of periastron time of a binary pulsar by the emission of gravitational waves.…

Phenomenology of SUGRA Extensions of the Starobisnky Model

Ping Kwan Man Ellgan

We analyze BI model in a complete form and compare the predictions with that of Starobinsky model. Under the parameter constraints in Planck 2018, we find that the dynamics of the…

Cosmological Dynamics and Double Screening of DBI Galileon Gravity

Sirachak Panpanich, Supakchai Ponglertsakul, Kei-ichi Maeda

We investigate cosmological dynamics and screening mechanism of the Dirac-Born-Infeld (DBI) Galileon model. The model has been divided into two regimes, one has positive signs in f…

Stable Singularity-free Cosmological Solutions in non-projectable Horava-Lifshitz Gravity

Mitsuhiro Fukushima, Yosuke Misonoh, Shoichiro Miyashita +1

We find stable singularity-free cosmological solutions in non-flat Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime in the context of Hořava-Lifshitz (HL) theory. Although we e…
