Dark matter particles production at the LHC accelerator
One of the greatests puzzles of science today is the nature
of the dark matter. Misterious dark matter particles account
for 1/4 of the Universe density. It is highly probable, that
the LHC accelarator, which will begin to operate in 2007,
will become a factory of such particles, and the CMS experiment, working at the LHC, will answer the question about their nature.
Among many possible scenarios there are such, in which theses particles come from cascade decays of massive, charged, weakly interacting, long-lived particles. The goal of the thesis will be evaluation of the observability of these scenarios and definition of measurable parameters of the models.

Multi-messenger study of rapidly changing astrophysical objects
The Universe is full of very dynamic objects: supernovae,
gamma ray bursts, active galactic nulei, etc. Stars explode
and collide, neutron stars and black holes are created.
Recent years brought important progress in the studies of such objects thanks to the multi-messenger approach,
i.e. the same objects beeing observed by cosmic rays,
neutrinos, electromagnetic radiation from radio waves
to TeV photons. One hopes for detection of gravitational waves in the future.
The "Pi of the Sky" project lead by Soltan Institute
registers changes of brightness of astrophysical objects
within seconds. The goal of the thesis would be to compare
these observations against data from other experiments
in order to understand better the dynamics of the processes
in question.
