A Cepheid systematics-free test of $H_{0}$ to $≲ 2.5%$ accuracy using SH0ES photometry

Doron Kushnir, Amir Sharon

The recent SH0ES determination of the Hubble constant, $H_{0} = 73.04 \pm 1.04$ km/s/Mpc, deviates significantly by $\approx 5 I ¨ $ from the \textit{Planck} value, stimulating discussions o…

Reassessing the Constraints from SH0ES Extragalactic Cepheid Amplitudes on Systematic Blending Bias

Amir Sharon, Doron Kushnir, Wenlong Yuan +2

The SH0ES collaboration Hubble constant determination is in a $\sim 5 I ¨ $ difference with the $P l an c k$ value, known as the Hubble tension. The accuracy of the Hubble constant measu…
