Probing the Charged Hayward Black Hole in Dark Matter and String Cloud Environments through Shadow, Geodesics, and Quasinormal Spectrum

Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı

We construct a charged Bardeen black hole (BH) surrounded by perfect fluid dark matter (PFDM) and coupled to a cloud of strings (CS). The metric function combines the magnetic mono…

Observational signatures of charged Bardeen black holes in perfect fluid dark matter with a cloud of strings

Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı

We construct a charged Bardeen black hole (BH) surrounded by perfect fluid dark matter (PFDM) and coupled to a cloud of strings (CS). The metric function combines the magnetic mono…

Effects of spontaneous Lorentz Symmetry breaking on Letelier-AdS charged black holes within Kalb-Ramond gravity

Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı

In this study, we investigate the geodesic motion of massless particles -- specifically photons -- in the spacetime of a charged anti-de Sitter (AdS) black hole (BH) surrounded by…

Charged Simpson-Visser AdS Black Holes: Geodesic Structure and Thermodynamic Properties

Faizuddin Ahmed, Ahmad Al-Badawi, Mohsen Fathi

In this article, we apply the Simpson-Visser (SV) regularization scheme to Anti-de Sitter (AdS) charged black holes and investigate the resulting spacetime geometry in detail, with…

Optical appearance, Hawking radiation, and Barrow thermodynamics of Letelier black hole in electromagnetic universe

İzzet Sakallı, Erdem Sucu, Ahmad Al-Badawi +1

We present an investigation of a static, spherically symmetric Letelier black hole (BH) immersed in an electromagnetic universe (EMU), characterized by the cloud of strings (CoS) p…

Letelier black hole immersed in an electromagnetic universe

Ahmad Al-Badawi, Faizuddin Ahmed, İzzet Sakallı

We investigate a static, spherically symmetric black hole solution surrounded by a cloud of strings and immersed in an electromagnetic universe. By deriving the event horizon from…
