Abstract

In this work, we have worked out dynamical aspects for the particles moving in the Dyonic Mod Max spacetime. We have calculated the innermost stable circular orbit (ISCO) around black hole in Dyonic Mod Max and explored its implications for different microquasars. Considering the Dyonic Mod Max black hole as a microquasar source, we have studied quasi-periodic oscillation (QPO) around such a black hole. Finally, we determine constraint values for the parameters Q and γ in the Dyonic ModMax spacetime by analyzing QPOs observed from the quasars GRO J1655–40, XTE J1550–564, XTE J1859+226, GRS 1915+105, and H1743-322. We use the Monte Carlo Markov Chain (MCMC) method to analyze the observational data, which helps us refine these parameters and better understand the behavior of black holes in the Dyonic ModMax model.

期刊介绍： The journal welcomes manuscripts on theoretical models, simulations, and observations of highly energetic astrophysical objects both in our Galaxy and beyond. Among those, black holes at all scales, neutron stars, pulsars and their nebula, binaries, novae and supernovae, their remnants, active galaxies, and clusters are just a few examples. The journal will consider research across the whole electromagnetic spectrum, as well as research using various messengers, such as gravitational waves or neutrinos. Effects of high-energy phenomena on cosmology and star-formation, results from dedicated surveys expanding the knowledge of extreme environments, and astrophysical implications of dark matter are also welcomed topics.
