Atiyah-Hitchin in Five Dimensional Einstein-Gauss-Bonnet Gravity
Michael Butler, Masoud Ghezelbash, Erfan Massaeli +1
We construct a new class of stationary exact solutions to five-dimensional Einstein-Gauss-Bonnet gravity. The solutions are based on four-dimensional self-dual Atiyah-Hitchin geome…

Warm Higgs G-inflation: predictions and constraints from Planck 2015 likelihood
Maysam Motaharfar, Erfan Massaeli, Hamid Reza Sepangi
We reconsider a recently proposed warm G-inflation scenario in which the Galileon scalar field concurrently dissipates its kinetic energy as the radiation fluid throughout inflatio…

Power spectra in warm G-inflation and its consistency: stochastic approach
Maysam Motaharfar, Erfan Massaeli, Hamid Reza Sepangi
Recently, it has been realized that the so-called G-inflation model inspired by supplementing a generalized covariant Galileon-like non-linear derivative self-interacting term to t…
