where is the scale factor of the universe and the dots indicate derivatives by proper time. The expansion of the universe is said to be "accelerating" if is positive (recent measurements suggest it is), and in this case the deceleration parameter will be negative. The minus sign and name "deceleration parameter" are historical; at the time of definition was thought to be positive, now it is believed to be negative.

Universe with matter in it will be continuously decelerating over time since the big bang. Cosmologists refer to this as the deceleration parameter, and it's written as a little q with a subscript zero. In standard cosmologies q0 equals a half for a flat universe, less than a half for an open universe, and more than a half for a closed universe. The relationship is more complex in cosmologies with a cosmological constant. Measuring the deceleration depends on comparing the properties of distant objects like galaxies with nearby objects. This is difficult because of the problem of look-back time. When we look at distant objects we are looking at objects as they were and not as they are now, so when we compare objects that are distant or high redshift wit...

Dynamics of f(Q,T) Gravity with Variable Deceleration Parameter
Speaker:
Laxmipriya Pati
Talk abstract:
In this paper, we have studied the dynamical behaviour of f(Q; T) gravity, which is an extended version of the symmetric teleparallel gravity. Q and T respectively be the non-metricity and trace of the energy momentum tensor. Two functional form of f(Q, T) such as, (i) f(Q, T) = aQ + bT and f(Q, T) = aQ^(n+1) + bT , where a, b and n are the model parameters are investigated. Two cosmological models are presented by incorporating the hybrid scale factor to analyse the behaviour of the models at late time of the evolution. The equation of state parameter is lying in the quintessence region at late...

Unless astronomers can model and predict the rate of cosmic evolution of stellar systems like galaxies they can not do cosmological tests based on a comparison of distant objects with nearby objects. To this point it has been very difficult to conduct this type of cosmological test.
