Constraining deceleration, jerk and transition redshift using cosmic
  chronometers, Type Ia supernovae and ISW effect
  In this study we present constraints on the deceleration (q) and jerk (j)
parameters using the late time integrated Sachs-Wolfe effect, type Ia
supernovae, and H(z) data . We first directly measure the deceleration and jerk
parameters using the cosmic chronometers data with the Taylor series expression
of H(z).However, due to the unusual variations in the deceleration parameter
with slight changes in other parameters like snap (s) and lerk (l), we found
that direct measurements using the series expression of the H(z) is not a
suitable method for non-Lambda-CDM models and so we will need to derive the
deceleration parameter after constraining density parameters and dark energy
equation of state parameters. Then we present derived values of the
deceleration parameter from Lambda CDM, WCDM and CPL models. We also discuss
the transition redshift (zt) in relation with the deceleration parameter.
