The latest astronomical
observations indicate that the normal matter (baryons) which we are
familiar with comprises only 4 or 5 percent of the cosmic total
The rest of the Universe are made up of the unknown dark matter
(20%-25%) and dark energy (about 70%) which has extremely strange
properties. What is the
nature of the dark matter and dark energy? This is one of the most
momentous problems in modern science. The solution of this problem
would enable us to have a much more profund understanding
of the Nature, and may leads to a new revolution in science.
To strenghen the research on the dark matter and dark energy problem,
the National Astronomical Observatory has set up our group, with a
focus on solving this scientific problem with astrophysical methods. In
researches, many methods and theories of astronomy and physics are
so in fact the researches of our group covers many other aspects of
cosmology and particle astrophysics, e.g. very early universe, gravity
microwave background radiation, large scale structure, galaxy formation
and evolution, supermassive blackhole, the first generation of objects
and cosmic reionization, gamma-ray astronomy, cosmic ray, neutrino
astronomy, etc. The research of our group is mainly theoretical,
theory, semi-analytical model, numerical simulation, and data analysis.
At the same time, we do have frequent communication and cooperation
with several observational groups, and observational researches may
also be considered if condition permits.
Our group began its activities in 2005, and in March 2006 it is
We welcome colleagues to communicate and collaborate with us, and we
people who are interested in cosmological research to apply for
positions in our group.
