DOI: 10.1088/1361-6382/ac5053
Abstract: We introduce new methods to numerically construct for the first time stationary axisymmetric black hole solutions in Einstein-aether theory and study their properties. The key technical challenge is to impose regularity at the spin-2, 1,… read more here.

DOI: 10.1088/1475-7516/2017/04/015
Abstract: In this paper, we will analyse the cosmological models in Einstein-aether gravity, which is a modified theory of gravity in which a time-like vector field breaks the Lorentz symmetry. We will use this formalism to… read more here.

DOI: 10.1088/1674-1137/44/6/065106
Abstract: We study matter accretion onto Einstein-aether black holes by adopting the Hamiltonian approach. The general solution of accretion is discussed using the isothermal equation of state. Different types of fluids are considered, including ultra-relativistic, ultra-stiff,… read more here.

DOI: 10.1103/physrevd.102.024076
Abstract: We propose accurate calculations of quasinormal modes of black holes in the Einstein-aether theory, which were previously considered in the literature, partially, with insufficient accuracy. We also show that the arbitrarily long lived modes, quasi-resonances,… read more here.

DOI: 10.1103/physrevd.99.023010
Abstract: Gravitationally bound hierarchies containing three or more components are very common in our Universe. In this paper we study the periodic gravitational wave (GW) form, its polarizations, the response function, the Fourier transform, and the… read more here.

Abstract: We investigate generalized Einstein-Aether theories that are compatible with the Planck Cosmic Microwave Background (CMB) temperature anisotropy, polarisation, and lensing data. For a given dark energy equation of state, $w_{\rm de}$, we formulate a designer… read more here.

DOI: 10.1142/s0218271821501078
Abstract: In this work we present all the possible solutions for a static cylindrical symmetric spacetime in the Einstein-Aether (EA) theory. One of these solutions are the generalization in EA theory of the Levi-Civita (LC) spacetime… read more here.
