I had said a few months ago about being on a paper with a giant author list (at least for me).

Anyway, that paper is now on the arXiv, and it's a fun one: https://arxiv.org/abs/2312.03639

"The Initial Mass Function Based on the Full-sky 20-pc Census of ∼3,600 Stars and Brown Dwarfs"

We (and I use the part of we that includes "me" *very* loosely) took a census of the neighborhood, and the result is a stellar mass function down to 5 Jupiter masses. #Astrodon #Astrophysics #Astronomy #BackyardWorlds

"The nuclear star cluster has mainly been seen, quite rightly, as a very ancient part of the galaxy. But the researchers’ new discovery of such young stars indicates that there is also active star formation going on in this ancient component of the Milky Way. However, dating stars 25,000 light years from Earth is not something that can be done in a hurry."

Each time I have imaged it, I have tried to also bring out the blue oxygen in the right but haven't had much success yet. This image is 36 five-minute exposures captured over two partly cloudy nights which caused me to throw away many exposures. Maybe that's why I have trouble capturing the oxygen

I'm very isolated, with my nearest neighbor a quarter mile away, and it's a mile away to my next neighbor. And so on. So it should be dark here, but there's a lone street/security light in the middle of the property and it spoils any #astrophotography shot taken in that direction. The electric co-op owns it but I pay for it. My spouse says we should have them turn it off. It would be very dark.
Here's M33 taken just west of the light. Lots of data lost to glow.

Did you know that galaxies are almost empty? Stars within them are so far apart that when galaxies clash their individual stars don't collide – they just get tossed around due to gravitational interactions, distorting the shapes of the galaxies.

Very neat follow-up study of the radio detections of millisecond pulsars in the Omega Centauri core, with CHANDRA, finding correlation between spider pulsar companion mass and X-ray luminosity.

The redbacks give off more X-rays!

Omega Cent. is a super interesting Globular Cluster to study with pulsars, as it is so much more massive than other Milky Way GCs. Some folks think it is the remnant component of a former, now cannibalised galaxy - which makes probing the dynamics and binary configurations in the core interesting!

A rare case of an in-sync gravitational lockstep in a solar system.

A star smaller and cooler than our Sun hosts a truly strange family of planets: six “sub-Neptunes” – possibly smaller versions of our own Neptune – moving in a cyclic rhythm. This orbital waltz repeats itself so precisely it can be readily set to music.

that's a more complete view, also including the evolution of electron spectra (three models, from without Fermi reacceleration terms to having all of them in the Fokker Planck solver) and of their synchrotron emission, for an evolving cluster of galaxies.

It really looks like we have a radio halo formation from turbulent reacceleration here, one of the first ever in cosmology...

First discovery of a disc around a star in another galaxy! A few years ago astronomers pointed ESO's Very Large Telescope to our galactic neighbour, the Large Magellanic Cloud. They spotted two jets coming out of a dust-hidden star, a sign that it might have a disc around it.

Now, using ALMA, they've found evidence of such a rotating gas disc, similar to those in our galaxy where planets form around young stars.
