New Tsallis holographic dark energy with apparent horizon as IR-cutoff in non-flat Universe

New Tsallis holographic dark energy with apparent horizon as IR-cutoff studied by considering non-flat Friedmann-Lemaitre-Robertson-Walker metric. The accelerating expansion phase of the Universe is described using deceleration parameter, equation state parameter and density different values NTHDE "$\delta$". Universe's transition from a decelerated to an accelerated expanding smooth graph parameter. Depending on distinct "$\delta$", we have explored quintessence behavior We used Hubble data sets obtained Cosmic Chronometric methods distance modulus measurement Type Ia Supernova fit parameters. Stability our model analyzing squared speed sound investigated well.
