Testing the Distance Duality Relation with Cosmological Observations at high Redshift using Artificial Neural Network
Yukang Xie, Yang Liu, Puxun Wu +2
The cosmic Distance Duality Relation (DDR) is a fundamental prediction of metric gravity under photon number conservation. In this work, we perform a model-independent test of the…

Primordial Gravitational Waves in Parity-violating Symmetric Teleparallel Gravity
Rongrong Zhai, Chengjie Fu, Xiangyun Fu +2
In this paper, we investigate the inflationary phenomenology of parity-violating (PV) extensions of symmetric teleparallel gravity by applying this PV gravity theory to axion infla…
