Title:
'Universe in TeV gamma rays: results of the H.E.S.S. experiment'
-----------------------------------------------------------------
Abstract:
Recent investigations of the Universe are based on observations
in a very wide range of electromagnetic spectrum, from radio waves
with photon energies ~10^-5 eV, up to very high energy gamma rays
reaching ~100 TeV. In this last VHE domain (100 GeV – 100 TeV)
practically full our knowledge was collected in a few last years
due to results of the H.E.S.S. observatory at the southern hemisphere,
and working somewhat shorter MAGIC and VERITAS experiments at
the northern hemisphere. During my lecture I will present highlights
of H.E.S.S. observational results of cosmic sources (astrophysical
particle accelerators), such as e.g. supernova remnants, pulsar wind nebulae, stellar binary systems, a central black hole in Our Galaxy,
or active galactic nuclei. I will also mention application of
TeV astronomy to study some fundamental problems of physics and
cosmology (quantum gravity, a nature of dark matter). A short
information about the current preparatory phase proceedings for
the Cherenkov Telscope Array (CTA), a new generation TeV gamma ray
observatory, will complete the presentation.
