The enhanced nitrogen maximum in this starburst galaxy NGC 5253 in the local universe is almost at the same level as in galaxies in the early universe that are now frequently observed with JWST. [3/3]

The main topic of the paper is the detection of nitrogen enrichment which is 2-3x higher in the region around the central massive super star clusters than in more distant regions.
We think that the massive young stars (up to 40 Wolf-Rayet stars seem to exist in the center) in the central clusters have expelled such an amount of nitrogen-rich material that just had enough time to cool and mix with the pre-existing material to show up as enhancement in the optical line emission.

Very happy to have contributed a bit to Brigitte Pruijt's paper on NGC 5253 using the MUSE narrow-field mode data. (Had completely forgotten to post about it until now, though.🙄) With that we can spatially resolve the starburst galaxy to about 2 pc and get spectroscopy of everything in the field. We can first produce a variety of nice color maps. [1/3]

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. 😀

I contributed a bit of data processing and got to be co-author on another paper in this month's A&A. 😀
Martin Ochmann was able to use narrow-field MUSE data to extract and model the Ca-triplet and OI emission (1st picture) of the accretion disk of NGC 4593. I know very little about AGN and their BLR but apparently the one can get a nearly perfect fit to a double-peaked CaII profile (2nd picture) using a not too complex disk model. The resulting low intrinsic turbulence seems to be something special...

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.

New paper by Norberto Castro where I was able to contribute (https://arxiv.org/abs/2410.21391). In MUSE NFM data we discovered what seems to be an outflow originating from the massive Wolf-Rayet binary Mk34 in the 30 Doradus region.The ionized gas in the direction of the outflow (red polygon in the image) has line ratios that sets it apart from the surrounding medium.

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.

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.

New paper on Tidal Dwarf Galaxies (TDGs) led by Navyasree Kovakkuni and Federico Lelli (I had a small part): http://arxiv.org/abs/2309.06478
Some (parts) of the TDGs show up as pretty extreme starbursts in the spatially-resolved KS relation.
