Identification of extragalactic sources of the highest energy EGRET photons by correlation analysis
D. S. Gorbunov, P. G. Tinyakov, I. I. Tkachev +1
We found significant correlations between the arrival directions of the highest energy photons (E>10 GeV) observed by EGRET and positions of the BL Lac type objects (BL Lacs). The…

Cosmological attractors in massive gravity
S. Dubovsky, P. Tinyakov, I. Tkachev
We study Lorentz-violating models of massive gravity which preserve rotations and are invariant under time-dependent shifts of the spatial coordinates. In the linear approximation…

Massive graviton as a testable cold dark matter candidate
S. L. Dubovsky, P. G. Tinyakov, I. I. Tkachev
We construct a consistent model of gravity where the tensor graviton mode is massive, while linearized equations for scalar and vector metric perturbations are not modified. The Fr…
