The effective volume of supernovae samples and sample variance
Zhongxu Zhai, Will J. Percival, Zhejie Ding
The source of the tension between local SN Ia based Hubble constant measurements and those from the CMB or BAO+BBN measurements is one of the most interesting unknowns of modern co…

Sample Variance for Supernovae Distance Measurements and the Hubble tension
Zhongxu Zhai, Will J. Percival
Recent local measurements of the Hubble constant made using supernovae have delivered a value that differs by 5 (statistical error) from predictions using the Cosmic Micro…
