Model-independent traversable wormholes from baryon acoustic oscillations

Deng Wang

In this paper, we investigate the model-independent traversable wormholes from baryon acoustic oscillations. Firstly, we place the statistical constraints on the average dark energ…

Wormholes in a viscous universe

Deng Wang

We study the static and spherically symmetric wormhole spacetime configurations at present time in a viscous universe. Considering three classes of viscous models, i.e., bulk visco…

Do we expect to detect electromagnetic radiation from merging stellar mass black binaries like GW150914? No

Shuang-Nan Zhang, Yuan Liu, Shuxu Yi +2

Context: The LIGO consortium announced the first direct detection of gravitation wave event GW150914 from two merging black holes; however the nature of the black holes are still n…

Constraining the range of Yukawa gravity interaction from S2 star orbits II: Bounds on graviton mass

Alexander F. Zakharov, Predrag Jovanovic, Dusko Borka +1

Recently LIGO collaboration discovered gravitational waves \cite{Abbott_16} predicted 100 years ago by A. Einstein. Moreover, in the key paper reporting about the discovery, the jo…

Effective gravitational couplings for cosmological perturbations in generalized Proca theories

Antonio De Felice, Lavinia Heisenberg, Ryotaro Kase +3

We consider the finite interactions of the generalized Proca theory including the sixth-order Lagrangian and derive the full linear perturbation equations of motion on the flat Fri…

Cosmology in generalized Proca theories

Antonio De Felice, Lavinia Heisenberg, Ryotaro Kase +3

We consider a massive vector field with derivative interactions that propagates only the 3 desired polarizations (besides two tensor polarizations from gravity) with second-order e…

Exact solutions in f(R) theory of gravity

Changjun Gao, You-Gen Shen

We find a new method for looking for the static and spherically symmetric solutions in theory of gravity. With this method, a number of new solutions in terms of the analyti…

Screening fifth forces in generalized Proca theories

Antonio De Felice, Lavinia Heisenberg, Ryotaro Kase +3

For a massive vector field with derivative self-interactions, the breaking of the gauge invariance allows the propagation of a longitudinal mode in addition to the two transverse m…

Testing Einstein's Equivalence Principle with Cosmological Fast Radio Bursts behind Clusters of Galaxies

Shuang-Nan Zhang

Aims: Recently, cosmological fast radio bursts (FRBs) have been used to provide the most stringent limit up to date on Einstein's Equivalence Principle (EEP). We study how to furth…
