Instability and no-hair paradigm in d-dimensional charged-AdS black holes
Afsaneh Rahmani, Mohsen Khodadi, Matin Honardoost +1
Is it possible the no-hair paradigm is violated when a black hole undergoes an instability? Employing massless charged scalar perturbations, we address this question within the con…
Thermal phase transition in -charged -scalar theory
A. Rahmani, M. Honardoost, H. R. Sepangi
We investigate instabilities of -charged black holes by a massive charged scalar field in a linear perturbation regime. We study tachyonic instabilities as the near…
Final state of instabilities in Born-Infeld black holes
A. Rahmani, M. Honardoost, H. R. Sepangi
We study two types of linear instabilities in Einstein-Born-Infeld-scalar field theory and show that small Born-Infeld (BI) black holes suffer from superradiant instability within…
Hairy Waves: Gravitational Waves in the presence of Screening Mechanism
Matin Honardoost, Nima Khosravi, Nafiseh Rahmanpour
We consider a binary system in the context of screened modified gravity models and investigate its emitted gravitational wave which has been shown that is a hairy wave. We derive p…
Superradiant instability and asymptotically AdS hairy black holes in -charged scalar field theory
A. Rahmani, M. Honardoost, H. R. Sepangi
We study the phenomena of superradiance for -Maxwell black holes in an AdS space-time. The AdS boundary plays the role of a mirror and provides a natural confining system tha…
Symmetron with a non-minimal kinetic term
M. Honardoost, D. F. Mota, H. R. Sepangi
We investigate the compatibility of the Symmetron with dark energy by introducing a non-minimal kinetic term associated with the Symmetron. In this new model, the effect of the fri…
