DESCRIPTION:Speakers: Pratik P. Ray (Vellore Institute of Technology-AP Un
 iversity)\nThis study offers a comprehensive reconstruction of modified Te
 leparallel (f(T)) gravity model with three distinct non-linear as well as 
 novel forms employing a hybrid scale factor to depict the expansion histor
 y of the universe. We investigate a physically motivated cosmological para
 metrization through this hybrid scale factor that can explain a smooth tra
 nsition from an early decelerated epoch to the present accelerated evoluti
 on. This scale factor is then used to derive the corresponding model param
 eters. These parameters are rigorously constrained using the Monte Carlo M
 arkov Chain (MCMC) analysis with the help of Bayesian statistics and incor
 porating late-time observations from Hubble\, Baryon Acoustic Oscillations
  (BAO) and Patheon+SH0ES datasets. The investigation of dynamical paramete
 rs such as the equation of state parameter and cosmological parameters ind
 icates alignment with an accelerated expansion phase in both the present a
 nd late time epochs. Validation is conducted by assessing the energy condi
 tions\, verifying the feasibility of the model forms with particular empha
 sis on the violation of the strong energy condition that indicates dark en
 ergy dominance in modified gravity scenarios. This investigation has been 
 instrumental in determining models that remain consistent with cosmologica
 l observations and theoretical requirements. The reconstructed forms of th
 e model effectively mimic ΛCDM at late times\, providing significant insi
 ghts into possible extensions of general relativity and bolstering f(T) gr
 avity theory as a robust explanation for cosmic acceleration.\n\nhttps://i
