Formation of the molecular clouds in the external galaxies
Khoperskov Sergey
Sternberg Astronomical Institute
DRIVER: The aim of the project is the simulations of the structure of the molecular clouds with taking into account multiphase interstellar medium (ISM), UV background, chemical reactions, self gravity of the gas and the large scale structure of the galactic discs. The most of the molecular gas forms on the dust grain surface then an important issue is the process of the clouds formation due to dynamical segregation of the ISM dust on sizes, charge and masses of grains.
STRATEGY: The evolution 3D the galactic discs will be simulated numerically. This models should be based on the observational data for sample of the THINGS (The HI Nearby Galaxy Survey) disc galaxies. Segregation of the ISM dust due to turbulent motions within magnetized ISM and galactic halo will be simulated using the hybrid N-body/MHD approach.
OBJECTIVE: Searching of the scenarios of formation and evolution of the molecular clouds in external galaxies. Particular interest is the determination of the dominant mechanism in the process of clouds birth in an inhomogeneous interstellar medium.
IMPACT: The expected results of numerical experiments will help to explain the observed statistical characteristics of molecular hydrogen clouds in external galaxies. Also, these calculations will predict the early stages of the current star formation in galaxies. Accounting segregation of dust may explain the observed heterogeneity of the infrared radiation in the maps of external galaxies obtained by Spizer and Herschel space telescopes.
USAGE: In addition to the direct results of analysis of the properties of molecular gas in galaxies, the calculations of interest may be applicable in a wide range of astrophysical problems. The results of the simulations of the formation and evolution of molecular clouds can be used as initial conditions for the current star formation in galaxies. At the same time, a large sample of clouds allows to test different models of accretion processes. Fundamental application of the results of the calculations is the determination the diffusion mode of charged dust particles in the interstellar medium gas which is partially magnetized.
