Density-Shear Baryon Acoustic Oscillation as a Cosmological Consistency Check
Kwan Chuen Chan, Yin Li, Jamie McCullough
Tensions often arise between different datasets in cosmology, and consistency tests can serve as a powerful tool for diagnosing potential issues. Density-shear Baryon Acoustic Osci…

Photo- Estimation with Normalizing Flow
Yiming Ren, Kwan Chuen Chan, Le Zhang +6
Accurate photometric redshift (photo-) estimation is a key challenge in cosmology, as uncertainties in photo- directly limit the scientific return of large-scale structure an…

Optimizing Redshift Distribution Inference through Joint Self-Calibration and Clustering-Redshift Synergy
Weilun Zheng, Kwan Chuen Chan, Haojie Xu +2
Accurately characterizing the true redshift (true-) distribution of a photometric redshift (photo-) sample is critical for cosmological analyses in imaging surveys. Clusterin…
