Sgr A* Shadow Study with KTN Space Time and Investigation of NUT Charge Existence
M. Ghasemi-Nodehi
In this paper, I investigate the existence of the NUT charge through the KTN spacetime using shadow observations of Sgr A*. I report that the range of my constraint for the NUT cha…
Shadow, quasinormal modes and quasiperiodic oscillations of rotating Kaluza-Klein black holes
M. Ghasemi-Nodehi, Mustapha Azreg-Aïnou, Kimet Jusufi +1
In this paper we study the shadow of rotating Kaluza-Klein (KK) black holes and the connection between the shadow radius and the real part of quasi-normal modes (QNMs) in the eioko…
Iron line reverberation mapping in Ghasemi-Nodehi-Bambi background
M. Ghasemi-Nodehi
The reverberation associated with the iron line is the time lag between direct photons from the corona and the photons reflected from the disk. The resulting line spectrum is calle…
Testing Ghasemi-Nodehi-Bambi metric parameters with quasi-periodic oscillations
M. Ghasemi-Nodehi, Youjun Lu, Ju Chen +1
QPOs are seen as peak features in the X-ray power spectral density of stellar mass black holes and neutron stars, of which frequencies can be measured with high precision. These QP…
Testing Ghasemi-Nodehi-Bambi spacetime with continuum-fitting method
M. Ghasemi-Nodehi
The continuum-fitting method is the analysis of the thermal spectrum of the geometrically thin and optically thick accretion disk around stellar-mass black holes. A parametrization…
Testing exterior spacetime of the neutron star via X-ray reflection spectroscopy
M. Ghasemi-Nodehi
The exterior geometry of a neutron star can be approximated by relativistic multipole moments of a parametrized metric using Ernst potential formalism. This spacetime can be tested…
