On November 28, 2025, a scientific seminar titled "Spacetime and Particle Dynamics of Black Holes in Two Different Isotropic Dark Matter Halos" was held at Khazar University's Department of Physics and Electronics by Prof. Hassan Hassanabadi, a researcher from the University of Valladolid, Spain.

The event was attended by the university's faculty members, researchers, and students. In his presentation, Prof. Hassanabadi explained in detail that the behavior of black holes and their interaction with various astrophysical environments is one of the most current and complex research areas of modern science, and how the spacetime structure and particle dynamics of black holes in two different isotropic dark matter halos change based on theoretical models. He also presented the possible impacts of new approaches to the relationship between dark matter and black hole physics, based on the latest scientific findings.

The seminar proceeded in an interactive manner, with participants actively engaging in scientific discussions by addressing their questions related to the topic. The event was received with great interest by the participants and was evaluated as an effective platform for scientific exchange of ideas.
