... Moscow, Russia E-mail: krivosheev@iki.rssi.ru General notes · The Monte-Carlo method (s) is also called the statistical test method · An innumerable number of processes can be listed the outcome of which is not determined and has probabilistic nature, but these processes obey statistical laws, so to obtain the result we have to make multiple similar tests, i.e. to use the MC method · Because probabilistic processes are widely spread in nature, the MC ...

Correlated flashes of masers H2O . ... In 1981 - 1982 years it was revealed several Flashes of maser radiation of H2O radioline at wavelength 1.35 cm in the radio-sourse W49, developing practically synchronously at several radial velocities. It's known that components of the maser radiation of H2O radioline profile with different radial velocities arise in separate spatially diverse areas of a starformation. ...

Cosmic ray intensities (left) compared with predictions (right) from IBEX. The similarity between these observations and predictions as evidenced by the similar color regions supports the local galactic magnetic field direction determined from IBEX observations made from particles at vastly lower energies than the cosmic ray observations shown here. The blue area represents regions of lower fluxes of cosmic rays. ...
