Foreground Subtraction with a Tensor-Based Oriented Singular Value Decomposition Method for HI Experiments

Shifan Zuo, Xuelei Chen, Yi Mao

We introduce a native tensor-based framework for foreground mitigation in 21\,cm intensity mapping (IM), utilizing the Oriented Singular Value Decomposition (O-SVD) algorithm. Whil…
