The Hubble Constant from Type II supernovae

A 5% measurement of the Hubble constant from Type II supernovae

We continue upon our prior work of using type ii supernovae to provide another, largely-independent method to measure the value of the cosmic microwave background radiation ({\it by more than this so-called"hubble tension" has been confirmed by other independent methods, and thus does not appear to be a possibleconsequence of systematic errors.Here, we continue upon our prior work of using type ii supernovae to provide another, largely-independent method to measure the value of the cosmic microwave background radiation ({\it by more than this so-called"hubble tension" has been confirmed by other independent methods, and thus does not appear to be a possibleconsequence of systematic errors.Here, we continue upon our prior work of using type ii supernovae to provide another, largely-independent method to measure the value of the cosmic microwave background radiation ({\it by more than this so-called"hubble tension''has been confirmed by other independent methods, and thus does not appear to be a possibleconsequence of systematic errors.Using only geometric, or tip of the red giant branch (trgb) host-galaxy distance measurements, we derive km (statistical errors only), consistent with the local measurement but in disagreement by with the planck value.Using only cepheids we find km while using only the red giant branch we find km via 13 variants of our dataset, we derive a systematic uncertainty estimate of 1.5 km .The median value derived from these variants differs by just 0.3 km from that produced by our fiducial model.
