### Age problem in the holographic dark energy model

- Physics
- 2007

In this paper, we test the original holographic dark energy model with some old high redshift objects. The main idea is very simple: the universe cannot be younger than its constituents. We find that…

### Uncertainty on Determining the Dark Energy Equation of State due to the Spatial Curvature

- Physics
- 2006

We have studied the uncertainty on the determination of the dark energy equation of state due to a nonvanishing spatial curvature by considering some fundamental observables. We discussed the…

### Constraints on Dark Energy Models from Weak Gravity Conjecture

- Physics
- 2008

We study the constraints on the dark energy model with constant equation of state parameter w = p/ρ and the holographic dark energy model by using the weak gravity conjecture. The combination of weak…

### Measurement on the cosmic curvature using the Gaussian process method

- PhysicsMonthly Notices of the Royal Astronomical Society
- 2021

Inflation predicts that the Universe is spatially flat. The Planck 2018 measurements of the cosmic microwave background anisotropy favour a spatially closed universe at more than 2σ confidence…

### Direct evidence of acceleration from a distance modulus–redshift graph

- Physics
- 2007

The energy conditions give upper bounds on the luminosity distance. We apply these upper bounds to the 192 ESSENCE supernova Ia data to show that the Universe has experienced accelerated expansion.…

### Interacting holographic tachyon model of dark energy

- Physics
- 2010

We propose a holographic tachyon model of dark energy with interaction between the components of the dark sector. The correspondence between the tachyon field and the holographic dark energy…

### Super-acceleration on the brane through energy flow from the bulk

- Physics
- 2005

We consider a brane cosmological model with energy exchange between the brane and the bulk. Parametrizing the energy exchange term using the scale factor and Hubble parameter, we are able to exactly…

### Model independent measurement on the cosmic curvature

- Physics, Mathematics
- 2020

Inflation predicts that the Universe is spatially flat. The Planck 2018 measurements of the cosmic microwave background anisotropy favour a spatially closed universe at more than 2$\sigma$ confidence…

### Accelerated universe from gravity leaking to extra dimensions

- Physics
- 2002

We discuss the idea that the accelerated universe could be the result of gravitational leakage into extra dimensions over Hubble distances rather than the consequence of a nonzero cosmological…

### The Accelerated universe and the moon

- Physics
- 2003

Cosmologically motivated theories that explain small acceleration rate of the Universe via modification of gravity at very large, horizon or super-horizon distances, can be tested by precision…

### Constraints on alternative models to dark energy

- Physics
- 2003

Recent observations of type Ia supernovae strongly support that the universe is accelerating now and decelerated in the recent past. This may be evidence of the breakdown of the standard Friedmann…

### A NEW ALTERNATIVE MODEL TO DARK ENERGY

- Physics
- 2004

The recent observations of type Ia supernovae strongly support that the universe is accelerating now and decelerated in the recent past. This may be the evidence of the breakdown of the standard…

### Probing gravitation, dark energy, and acceleration

- Physics
- 2004

The acceleration of the expansion of the universe arises from unknown physical processes involving either new fields in high energy physics or modifications of gravitation theory. It is crucial for…

### Gravitational leakage into extra dimensions: Probing dark energy using local gravity

- Physics
- 2003

The braneworld model of Dvali-Gabadadze-Porrati (DGP) is a theory where gravity is modified at large distances by the arrested leakage of gravitons off our four-dimensional universe. Cosmology in…

### Supernova constraints on a holographic dark energy model

In this paper, we use the type Ia supernova data to constrain the model of holographic dark energy. For d = 1, the best fit result is Ωm0 = 0.25, the equation of the state of the holographic dark…

We generalize the mechanism proposed in a previous paper and show that a four-dimensional relativistic tensor theory of gravitation can be obtained on a delta-function brane in flat infinite-volume…
