School of Astronomy (SoA) Weekly Seminar
Reconstruction of the dynamics of Universe
Shant Baghramian- SUT
Abstract:
In
this
talk,
we
propose
an
inverse
method
to
reconstruct
the
Modified
gravity
action
in
Palatini
formalism,
using
the
dynamics
of
universe.
In
the
next
step
we
use
the
reconstruction
method
to
extract
the
dynamics
of universe
from
observational
SNIa
data.
Also
we
check
the
viability
of
reconstruction
method
and
impose
conditions
in
which
this
procedure
can
be
useful.
Finally
we
introduce
two
diagnosis
in
order
to
distinguish
between
LCDM
model
and
alternative
models
of
accelerating
universe.
