... Team . ... GRB mini-workshop 2006 . GRB workshop 2009 . ... GRB host galaxies are not peculiar objects. ... At present, long GRBs are identified with explosions of (probably) usual massive stars at the end of their evolution, i.e. massive (core-collapse) supernovae (CC-SNe). Thus, now GRBs are identified with 1) regions of the forming of massive stars (with massive star-forming) in host galaxies and 2) with explosions of short-living massive stars in the same galaxies - CC-SN/GRBs. ...

... 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 ...
