Scalarized black holes in the presence of the coupling to Gauss-Bonnet gravity
Masato Minamitsuji, Taishi Ikeda
In this paper, we study static and spherically symmetric black hole (BH) solutions in the scalar-tensor theories with the coupling of the scalar field to the Gauss-Bonnet (GB) term…
Stealth Schwarzschild solution in shift symmetry breaking theories
Masato Minamitsuji, Hayato Motohashi
We find stealth Schwarzschild solutions with a nontrivial profile of the scalar field regular on the horizon in the Einstein gravity coupled to the scalar field with the k-essence…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Vector boson star solutions with a quartic order self-interaction
Masato Minamitsuji
We investigate boson star (BS) solutions in the Einstein-Proca theory with the quartic order self-interaction of the vector field and the mass term $μ\bar{A}^…
General Relativity solutions in modified gravity
Hayato Motohashi, Masato Minamitsuji
Recent gravitational wave observations of binary black hole mergers and a binary neutron star merger by LIGO and Virgo Collaborations associated with its optical counterpart constr…
Black holes in quartic-order beyond-generalized Proca theories
Ryotaro Kase, Masato Minamitsuji, Shinji Tsujikawa
The generalized Proca theories with second-order equations of motion can be healthily extended to a more general framework in which the number of propagating degrees of freedom rem…
Black hole perturbations in vector-tensor theories: The odd-mode analysis
Ryotaro Kase, Masato Minamitsuji, Shinji Tsujikawa +1
In generalized Proca theories with vector-field derivative couplings, a bunch of hairy black hole solutions have been derived on a static and spherically symmetric background. In t…
