I was thinking about an zero cost and easy way to prove primacy creating a document. While there's no serious security here, at all, thanks to federation a post gets quickly propagated publicly so it would be very hard to hack all the host servers later. Like this, but etiquette requires only occasional use, this isn't a blockchain. Hashtag #dibs

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.

The first extragalactic maps of the faint diffuse interstellar bands (DIBs) in a galaxy at a distance of 100 Mpc.
Great work written up by a former astronomy student in Leiden. I could contribute some help with the MUSE data.

Mapping the diffuse interstellar bands $λ$5780 and $λ$6284 in the luminous infrared galaxy merger NGC 6240

[ABRIDGED] DIBs are faint absorption features of mainly unknown origin. Observational constraints on their carriers have been provided in the vast majority of the cases via observations in our Galaxy. Detections in other galaxies are scarce. However, they can further constrain the nature of the carriers by sampling different environments and they can put into test the ubiquity of the molecules creating these features. Using the MUSE data of the LIRG NGC 6240, we mapped the DIB5780 over an almost contiguous area of ~76.96 kpc^2 in the center of the system. We also traced the DIBl6284 over two separate areas toward the north and south of the system, with an extent of ~21.22 kpc^2 and ~31.41 kpc^2 (with a total detected area of ~59.78 kpc^2). This is the first time that the l6284 DIB has been mapped outside our Galaxy. Both maps were compared with the attenuation on the overall stellar population and the ionised gas. Both DIBs are detected in locations with high attenuation (E(B-V)_Gas} > 0.3 and E(B-V)_Stellar >0.1), supporting the connection between DIB carriers and dust. Moreover, when compared with other galaxies, DIBs correlate better with stellar than with the ionised gas attenuation. The DIBl6284 presents a stronger correlation with reddening than the l5780 DIB does that can be attributed to a different nature of the carriers causing these DIBs, or a combined effect of a dependency with the metallicity and the different locations where these DIBs have been measured. In addition, we show that NaI D strongly correlates with both DIBs and advocate the usage of DIBs as a first order tracer for amount of material, in the case where NaI D reaches saturation. The findings here show that DIB carriers can exist and survive in an environment as extreme as a galaxy hosting AGN and allow to envision the possibilities integral field spectrographs have to study DIBs well beyond our Galaxy.
