The use of the Monte Carlo methods in studying Fanaroff‐Riley II‐type radio sources

Abstract

General Monte Carlo methods are a broad class of algorithms relying on repeated random sampling to obtain numerical results in many physical problems. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in problems with many coupled degrees of freedom. I present the possible use of these methods in the case of the analytical KDA (Kaiser, Dennett-Thorpe & Alexander, 1997) model of Fanaroff-Riley's II (FR II)-type radio sources assuming the continuum injection process in the jet-intergalactic medium interaction. Since this model is characterized by a large number of free parameters and originally requires knowing the large number of parameters unknown a priori, the use of the Monte Carlo methods is well justified. I discuss the application of these methods and its reliability in the case of the selected real radio sources.
