Spherical Accretion on a Schwarzschild-MOG Black Hole
Ayyesha K. Ahmed, M Z A Moughal
In this paper we have examined spherical accretion onto Schwarzschild MOG Black Holes within the framework of Modified Gravity. Using isothermal test fluids, we analyze the behavio…
Destroying the Kerr Newman MOG Black hole with Scalar Test Field
Waqar Ahmad, Abdul Rehman Kashif, Ayyesha K. Ahmed
We test the weak cosmic censorship conjecture (WCCC) for the Kerr-Newman-modified gravity black hole (KN-MOG-BH) by interacting scalar test fields with the KN-MOG-BH. Neglecting ba…
Weak cosmic censorship conjecture for the (2+1)-dimensional charged BTZ black hole in the Einstein-Gauss-Bonnet Gravity
Ayyesha K. Ahmed, Sanjar Shaymatov, Bobomurat Ahmedov
It is well known that () dimensional charged BTZ (Banados, Teitelboim, Zanelli) black hole can be overcharged by a charged scalar field and a charged particle in contrast to t…
Weak Cosmic Censorship by Overspinning the Kerr-Newman-Kasuya Black Hole with Test Particle
Ayyesha K. Ahmed, Azad A. Siddiqui
We check the weak cosmic censorship conjecture by attempting to overspin the Kerr-Newman-Kasuya black hole with test particle. The study suggests that the Kerr-Newman-Kasuya black…
Accretion on High Derivative Asymptotically Safe Black Holes
M. Umar Farooq, Ayyesha K. Ahmed, Rong-Jia Yang +1
Asymptotically safe gravity is one effective approach to quantum gravity. It is important to differentiate the modified gravity inspired by asymptotically safe gravity. In this pap…
Spherical accretion by normal and phantom Einstein--Maxwell--dilaton black holes
Mustapha Azreg-Aïnou, Ayyesha K. Ahmed, Mubasher Jamil
We investigate the spherical accretion process for general static spherically symmetric fluids. We analyze this process by using the general metric ansatz for spherically symmetric…
Accretion on Reissner-Nordstrom-(anti)-de Sitter Black Hole with Global Monopole
Ayyesha K. Ahmed, Ugur Camci, Mubasher Jamil
In this paper, we investigate the accretion on the Reissner-Nordström anti-de-Sitter black hole with global monopole charge. We discuss the general solutions of accretion using the…
Astrophysical flows near gravity black holes
Ayyesha K. Ahmed, Mustapha Azreg-Aïnou, Sebastian Bahamonde +2
In this paper, we study the accretion process for fluids flowing near a black hole in the context of teleparallel gravity. Specifically, by performing a dynamical analysis b…
Cyclic and heteroclinic flows near general static spherically symmetric black holes
Ayyesha K. Ahmed, Mustapha Azreg-Aïnou, Mir Faizal +1
We investigate the Michel-type accretion onto a static spherically symmetric black hole. Using a Hamiltonian dynamical approach, we show that the standard method employed for tackl…
