After years of effort Davor Krajnović now published the M3G (MUSE Most Massive Galaxies) survey paper: https://arxiv.org/abs/2602.04968
He shows that from these massive galaxies, the brightest cluster galaxies (BCGs) are all slow rotators.
I think I like Fig. 5 the most, showing an astonishing five spin components in PGC 046832.

Hah, and while their attempts to take pictures of the ELT from the plane are just as bad as mine, I noticed that at 07:26 they are showing my MUSE picture demonstrating AO correction of Planetary Nebula NGC 6563. 😀

Cas van Erp's paper on the extragalactic diffuse interstellar bands (xDIBs) in NGC 6240 has now appeared in A&A.
This is the first real mapping of two of these very faint interstellar absorption features in a galaxy at such large distance. Only possible because the MUSE spectrograph is so sensitive and the students worked hard on these data.

This (Johnston et al., https://arxiv.org/abs/2404.04099) is already the 2nd paper on the partial MUSE data of #Malin1 (following Junais et al., https://www.aanda.org/articles/aa/full_html/2024/01/aa47669-23/aa47669-23.html).
Fingers crossed that we'll finally get the remaining 3/4 now that we have shown how useful it is.

The off-center source seems to be ionized mostly by star-formation (with a bit of shocks?), forming ~25x more stars than the nucleus. It could be a young star cluster to soon merge with the main nucleus.

Evelyn Johnston led the paper on the discovery of an "off-center compact source" in the giant LSB galaxy Malin 1 based on the existing MUSE data, now accepted at A&A.

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.

Happy to announce our paper on an #Orion #proplyd observed with the #musevlt was published!

See Roland Bacon's paper (https://arxiv.org/abs/2211.08493) on some of the deepest spectroscopic data that exists. And with this data release you can now all use it! #musevlt
