ASTROPHYSICS: REPORTS OUTLINE ASTROPHYSICS RESEARCH FROM R.M. AVAGYAN AND COLLEAGUES
Science Letter
February 10, 2009
"Modern concepts of the universe support the assumed existence of a
nongravitational source, known as dark energy, for which epsilon +
3 P< 0 (where epsilon is the energy density and P is the pressure),"
scientists in Yerevan, Armenia report (see also Astrophysics).
"This ensures accelerated expansion of the universe. This paper
examines a tensor-scalar variant of the theory of gravitation with
a conformally coupled scalar field," wrote R.M. Avagyan and colleagues.
The researchers concluded: "Various cosmological models are examined
and the possible evolutionary development of the universe with
accelerated expansion is discussed."
Avagyan and colleagues published their study in Astrophysics
(Cosmological model with a conformally coupled scalar
field. Astrophysics, 2008;51(4):565-574).
