Constraining the orbital eccentricity of inspiralling compact binary systems with Advanced LIGO
Marc Favata, Chunglee Kim, K. G. Arun +2
The detection of ~50 coalescing compact binaries with the Advanced LIGO and Virgo detectors has allowed us to test general relativity, constrain merger rates, and look for evidence…
Late-time acceleration in the coupled Cubic Galileon models
Kyoung Yee Kim, Hyung Won Lee, Yun Soo Myung
We investigate the linearly and quadratically coupled cubic Galileon models that include linear potentials. These models may explain the late-time acceleration. In these cases, we…
The absence of the Kerr black hole in the Hořava-Lifshitz gravity
Hyung Won Lee, Yun Soo Myung
We show that the Kerr metric does not exist as a fully rotating black hole solution to the modified Hořava-Lifshitz (HL) gravity with and case. We perform it by showi…
Massive gravitons dark matter scenario revisited
Hyung Won Lee, Kyoung Yee Kim, Yun Soo Myung
We reexamine the massive graviton dark matter scenario (MGCDM) which was recently considered as an alternative to dark energy models. When introducing the native and effective equa…
On the Ricci dark energy model
Kyoung Yee Kim, Hyung Won Lee, Yun Soo Myung
We study the Ricci dark energy model (RDE) which was introduced as an alternative to the holographic dark energy model. We point out that an accelerating phase of the RDE is that o…
Entropy bound of local quantum field theory with generalized uncertainty principle
Yong-Wan Kim, Hyung Won Lee, Yun Soo Myung
We study the entropy bound for local quantum field theory (LQFT) with generalized uncertainty principle. The generalized uncertainty principle provides naturally a UV cutoff to the…
Density perturbations in decaying holographic dark energy models
Kyoung Yee Kim, Hyung Won Lee, Yun Soo Myung
We study cosmological perturbations in the context of an interacting dark energy model, where the holographic dark energy with IR cutoff decays into the cold dark matter (CDM). For…
New agegraphic dark energy model with generalized uncertainty principle
Yong-Wan Kim, Hyung Won Lee, Yun Soo Myung +1
We investigate the new agegraphic dark energy models with generalized uncertainty principle (GUP). It turns out that although the GUP affects the early universe, it does not change…
Instability of agegraphic dark energy models
Kyoung Yee Kim, Hyung Won Lee, Yun Soo Myung
We investigate the agegraphic dark energy models which were recently proposed to explain the dark energy-dominated universe. For this purpose, we calculate their equation of states…
Holographic interacting dark energy in the braneworld cosmology
Kyoung Yee Kim, Hyung Won Lee, Yun Soo Myung
We investigate a model of brane cosmology to find a unified description of the radiation-matter-dark energy universe. It is of the interacting holographic dark energy with a bulk-h…
Non-flat universe and interacting dark energy model
Kyong Hee Kim, Hyung Won Lee, Yun Soo Myung
For non-flat universe of , we investigate a model of the interacting holographic dark energy with cold dark matter (CDM). There exists a mixture of two components arisen f…
Equation of state for an interacting holographic dark energy model
Hungsoo Kim, Hyung Won Lee, Yun Soo Myung
We investigate a model of the interacting holographic dark energy with cold dark matter (CDM). If the holographic energy density decays into CDM, we find two types of the effective…
