    I am particularly happy that this paper used the MUSE dataset of the Antennae Galaxy and found more than 200 PN candidates in these cubes with the DELF method. The short distance quoted in some H0-related papers now looks like a strong outlier. Here's the animation (Fig. 40) through [OIII]5007.

    This is the newest paper on distance measurements using the #PNLF with MUSE. While the archival datacubes were not optimal for the purpose, we were able to derive indepdentent distance to 17 of 20 galaxies, and determined H0 = 74.2 ± 7.2 (stat) ± 3.7 (sys) km/s/Mpc.
