I, Mominov S.B., entered the Faculty of Physics at Al-Farabi Kazakh National University in 2008 and graduated in 2012 with honors (red diploma). In the same year, I was admitted to the Master’s program at Al-Farabi Kazakh National University and successfully completed it in 2014. Since 2010, I have been working at the Research Institute of Experimental and Theoretical Physics (RIPETP), where I have been engaged in scientific research activities. As part of my professional development, I completed a research internship in the United States at Arizona State University under the supervision of Professors Davletov A.E. and Gabitov I.R. During this internship, I conducted research on the optical properties of metamaterials. From 2016 to 2019, I studied in the PhD program at Satbayev University, majoring in “6D072300 — Technical Physics.” During my doctoral studies, I actively published research results in Q1 journals with high impact factors. At present, my research interests are focused on problems in astrophysics. In particular, I study the capture cross-section for particles with mass m and for massless photons in various spacetime metrics.
