摘要：

We investigate the validity of cosmological models with an oscil-lating scale factor in relation to late-time cosmological observa-tions. We show that these models not only meet the required late time observational constraints, but can also alleviate the Hubble tension. As a generic feature of the model, the Hubble parameter increases near the current epoch due to its cyclical nature exhibiting the phantom nature allowing to address the said issue related to late time acceleration.& COPY; 2023 Elsevier Inc.
