Testing of the Uchaikin - Zolotarev power spectrum based on data for the interstellar medium

Power spectra are a key tool in modern research of the interstellar medium. Together with magnetohydrodynamic models of turbulence, their research helps to understand the physical processes occurring in this environment. The approximation of power spectra allows for a better understanding of energy transfer at various levels, which is important for studying the processes of star formation and magnetic fields in the interstellar medium. Various approximations of power spectra were compared, including the classical Kolmogorov spectrum, and the von Karman spectra developed on its basis, the lognormal spectrum, as well as the Uchaikin - Zolotarev spectrum. The Uchaikin - Zolotarev spectrum has proven to be a universal method for approximating power spectra and can be used in further research.
