Description
Last decade is marked with many breakthroughs in astrophysics of cosmic rays, and more are expected in the nearest future. Their proper interpretation is impossible without a well-developed propagation code. The GALPROP project celebrates its 22nd anniversary this year. This project is devoted to the development of a self-consistent model for cosmic-ray propagation in the Galaxy and associated diffuse emissions (radio, microwave, X-rays, gamma-rays). The project stimulated independent studies of the interstellar radiation field, distribution of the interstellar gas (H2, H I, H II), synchrotron emission and the Galactic magnetic field, and isotopic production cross sections. An important recent development is a combination of GALPROP with the HelMod code for cosmic ray propagation in the heliosphere. The combined model is able to reproduce a variety of measurements made in the local interstellar space (Voyager 1) and deep inside the heliosphere at different modulation levels, and at both polarities of the solar magnetic field. I will talk about recent updates to the GALPROP model and most important results.
