Radial Density Profiles of Time-Delay Lensing Galaxies

This leads to an uncertainty on H0 that can only be reduced if the mass distribution is independently known, for example from the stellar mass distribution or from the motions of gas and stars in the lensing galaxy: e.g. https://t.co/zz2jDxYWko https:/…

@BradleyKavanagh @GRAPPAInstitute For what it's worth, I too measured H0 once using time delay lenses, finding H0 ~ 64 km/s/Mpc... ... I mean, sure, +/- 8-9 km/s/Mpc, but whatever ... the controversy continues! (To be fair, we also showed how hard i…
