Radial perturbations of Ellis-Bronnikov wormholes in slow rotation up to second order
Bahareh Azad, Jose Luis Blázquez-Salcedo, Fech Scen Khoo +1
We consider slowly rotating Ellis-Bronnikov wormholes and investigate their radial perturbations (), expanding up to second order in rotation. We present the detailed…
Quasinormal modes of rapidly rotating Ellis-Bronnikov wormholes
Fech Scen Khoo, Bahareh Azad, Jose Luis Blázquez-Salcedo +4
We present for the first time a study of the quasinormal modes of rapidly rotating Ellis-Bronnikov wormholes in General Relativity. We compute the spectrum of the wormholes using a…
Quasinormal modes of Kerr black holes using a spectral decomposition of the metric perturbations
Jose Luis Blázquez-Salcedo, Fech Scen Khoo, Jutta Kunz +1
We report a new method to calculate the quasinormal modes of rotating black holes, using a spectral decomposition to solve the partial differential equations that result from intro…
Are slowly rotating Ellis-Bronnikov wormholes stable?
Bahareh Azad, Jose Luis Blázquez-Salcedo, Fech Scen Khoo +1
We investigate the radial perturbations of Ellis-Bronnikov wormholes () in a slowly rotating background expanded up to second order in rotation. We find indications t…
Polar modes and isospectrality of Ellis-Bronnikov wormholes
Bahareh Azad, Jose Luis Blázquez-Salcedo, Xiao Yan Chew +2
We consider polar perturbations of static Ellis-Bronnikov wormholes and derive the coupled set of perturbation equations for the gravitational and the scalar field. For massless wo…
Quasinormal modes of slowly rotating Kerr-Newman black holes using the double series method
Jose Luis Blázquez-Salcedo, Fech Scen Khoo
We calculate the spectrum of quasinormal modes of slowly rotating Kerr-Newman black holes. Using a perturbative double expansion method, second order in rotation and first order in…

Xiao Yan Chew, Dong-han Yeom, Jose Luis Blázquez-Salcedo
In this paper we study the properties of black holes and scalarons in Einstein gravity when it is minimally coupled to a scalar field with an asymmetric potential , const…
Universal relations for quasinormal modes of neutron stars in gravity
J. L. Blázquez-Salcedo, L. M. González-Romero, F. S. Khoo +2
We construct quasinormal modes for neutron stars in gravity in the Einstein frame, considering scalar masses in the sub-neV range. In particular, we investigate the fundament…
Radial perturbations of scalar-Gauss-Bonnet black holes beyond spontaneous scalarization
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Jutta Kunz +1
Spontaneous scalarization of black holes in scalar-Gauss-Bonnet (sGB) gravity is a very interesting phenomenon allowing black holes to circumvent the no-hair theorem and acquire sc…
Axial perturbations of hairy Gauss-Bonnet black holes with massive self-interacting scalar field
Kalin V. Staykov, Jose Luis Blázquez-Salcedo, Daniela D. Doneva +3
We study the axial quasinormal modes of hairy black holes in Gauss-Bonnet gravity with massive self-interacting scalar field. Two coupling functions of the scalar field to the Gaus…
Einstein-Maxwell-Chern-Simons Black Holes
Jutta Kunz, Jose Luis Blázquez-Salcedo, Francisco Navarro-Lérida +1
Black holes in 5-dimensional Einstein-Maxwell-Chern-Simons (EMCS) theory and their intriguing properties are discussed. For the special case of the CS coupling constant ,…
