The evidence of cosmic acceleration and observational constraints

Directly comparing the 6 expansion rate measured by type Ia supernovae data and the lower bound on the expansion rate set by the strong energy conditions or the null hypothesis that there never

The tension on the cosmological parameters from different observational data

Planck measurements of the cosmic microwave background power spectra find a lower value of the Hubble constant H0 and a higher value of the fractional matter energy density Ωm0 for the concordance

CONSTRAINTS ON THE LORENTZ INVARIANCE VIOLATION WITH GAMMA-RAY BURSTS VIA A MARKOV CHAIN MONTE CARLO APPROACH

In the quantum theory of gravity, for photons we expect the Lorentz Invariance Violation (LIV) and the modification of the dispersion relation between energy and momentum. The effect of the

PPN parameters in gravitational theory with nonminimally derivative coupling

The nonminimal coupling of the kinetic term to Einstein's tensor helps the implementation of inflationary models due to the gravitationally enhanced friction. We calculate the parametrized

The limit on $w'$ for tachyon dark energy

We get the same degeneracy relation between $w_0$ and $w_a$ for the tachyon fields as for quintessence and phantom fields. Our results show that the dynamics of scalar fields with different origins
