On redshift measurements
Abstract
Can redshift errors bias our measurement of the Hubble constant? This talk outlines some common errors in redshift measurements, in particular some common theoretical errors that should be avoided, and assesses how such errors can impact cosmological parameter inferences. There is the potential for significant errors, but the likelihood is that they are more random than systematic, so most resulting biases will be less than 1sigma at current precision. Nevertheless they have to be removed for the next generation of experiments to reach unbiased results. See 1907.12639 and 1909.00587.
