Ahmedov was a visiting professor and invited researcher at many universities and research centres in India, Germany, Italy, Czech Republic, China, Kazakhstan, Russia and Turkey. He is a frequent invited speaker at workshops and seminars abroad, and he collaborates closely with some leading researchers across Asia (China, India, Kazakhstan) and Europe (Czech Republic, Germany, Italy, Russia). He is known for his important results mainly obtained in the international collaboration: and has long-standing experience in applying general relativity to astrophysical problems and in the use of state of the 1 art numerical and analytical techniques in studying the electrodynamics of relativistic stars and black holes. In particular, he has developed the basic formalism to study the influence of strongly curved space-time on the properties of interior and exterior electromagnetic fields of magnetized relativistic stars and black holes. Force-free magnetosphere of oscillating and rotating magnetized neutron stars has been developed by him. A qualitative model for the explanation of the phenomenology of intermittent pulsars in terms of stellar oscillations that are periodically excited by star glitches has been also proposed. The conditions for radio emission in rotating and oscillating magnetars, by focusing on the main physical processes determining when the magnetars may be radio-loud or radio-quiet are studied by Ahmedov. Present observations showing a close connection between the burst activity of magnetars and the generation of the radio emission in the magnetar magnetosphere are naturally accounted. A general formalism to describe the black hole shadow as an arbitrary polar curve expressed in terms of a Legendre expansion has been developed and it has been shown that the new formalism provides an accurate and robust description of noisy observational data, with smaller error variances when compared to previous measurements of the distortion. Gravitational lensing by the various compact objects has been extensively studied. Since observations of gravitational waves from the coalescences of binary systems of compact objects by Advanced LIGO opened a new window to the strong-field regime of general relativity, Ahmedov has also paid attention to test the dynamical, nonlinear regime of the alternative theory of gravity with gravitational waves. In particular, quasinormal modes which dominate the signal detected by the Earth based gravitational wave detectors (LIGO, VIRGO, etc.) and gravitational instability of polytropic spheres containing region of trapped null geodesics as a tool of possible explanation of formation of the central supermassive black holes in galactic halos have been studied. Due to the discovery of gravitational waves by LIGO-VIRGO collaboration.
Ahmedov has studied the gravitational waves from coalescing black holes in inspiral stage and quasinormal modes from the black hole mergers. His other current important research is related to the description of shadow of various black holes and gravitational lensing from black holes. This study is very important with the recent detection of M87 supermassive black hole shadow in submillimeter radio diaposon by the Event Horizon Telescope using the Very Long Baseline Interferometry. Experimental tests of general relativity, general relativistic EM effects and fields for pulsars and magnetized rotating and oscillating neutron stars are also in the scope of his scientific interests. His 2 present research is also devoted to problems related to studying the electromagnetic and astrophysical processes around rotating oscillating neutron and strange stars and in X-ray binaries including highly magnetized neutron star. He is also conducting research on VLF (very low frequency) EM wave propagation in Earth ionosphere and study of the ionospheric disturbances caused by various atmospheric, terrestrial and extraterrestrial phenomena.
Bobomurat Ahmedov is among the leading scientists in the field of relativistic astrophysics, general relativity and gravitation. He is an accomplished theoretical physicist trained in the classical traditional scientific school and he together with his students have obtained several interesting results in this frontier area of relativistic astrophysics. He is the leader of the theoretical astrophysics group specialized in general relativity and relativistic astrophysics at the Ulugh Beg Astronomical Institute in Tashkent. Especially valuable are his contributions to our understanding what happens in the close surrounding of rotating astrophysical and supermassive black holes and oscillating and rotating strongly magnetized neutron stars. He is also well known for his work on energetics of black holes in magnetic field. He has a strong record of first class publications in highly ranked journals and a well established cooperation with leading European scientists (e.g. L. Rezzolla, Z. Stuchlik), leading Asian scientists (e.g. N. Dadhich, P. Joshi, C. Bambi), and leading scientific and educational institutions (e.g. Fudan University, Shanghai, China; ICTP, SISSA, Trieste, ICRA, Pescara, Italy; MaxPlanck-Institute, Golm, Frankfurt University, Germany; IUCAA, Pune, TIFR, Mumbai, India, Stanford University, USA) etc.

In Uzbekistan Bobomurat Ahmedov is one of the scientists who provides the students with a high-quality supervision of Bachelor diploma works, Master and PhD dissertations at the National University of Uzbekistan and the Ulugh Beg Astronomical Institute in Tashkent. Impact of the research activity conducted by Ahmedov in Uzbekistan is very important. First, he is a leader of single research group for the whole Uzbekistan (with ~35 millions of inhabitants) which is specialized in relativistic astrophysics and his experience and efforts are important for the further development of this subject in the region especially within the OEA-ICTP Network NT-01 coordinated by him. Second, the research group headed by Ahmedov has close relations with the National University of Uzbekistan in Tashkent and the Samarkand State University and graduate students from these universities are involved in research and educational programs in the relativistic astrophysics. Third, he is oftenly visiting the local scientific institutions and universities and make presentations on frontiers of general relativity and relativistic astrophysics. Fourth, graduate and PhD students from the local universities benefit from working with him. Almost majority part of the scientific results of Ahmedov have been obtained while his various scientific trips abroad because production of the high-level scientific results requires the strong scientific collaboration established by him.
Last but not least we have to mention the important role that Prof. Ahmedov plays for the education of physicists in Uzbekistan. Some of his PhD students provide meanwhile valuable contributions to our understanding of general relativity and relativistic astrophysics.
