Without doing a detailed look at the compressibility, most of the properties point to a very fast cooling timescale due to low gas support since it only appears in our hydro cases. I'd be interested in whether radiation would "fix" it, I would think it should based on your results with starforge

Final point I'll put here is that magnetic fields significantly contribute to the pressure, and therefore temperature, of the CNM environment. We find that the lower compressibility of the gas in MHD models prevents overcooling in lower density gas, maintaining ideal averrage temperatures of ~100 K.

Additionally, magnetic field orientations are found to be primarily perpendicular to the orientation of a filament denser than ~100 cm^-3, while their densest centers show evidence of a return to parallel alignment. This increases filamentary flow and accretion rates onto filaments, increasing mass.

We find velocity dispersions of 8 km/s to be ideal for the formation of structure even in high gas column density environment, expanding the flat relation between the two found by Kim&Ostriker2015. These dispersions necessarily come from the balance of gravitational energy turbulent kinetic energy.

My first paper is out now on the arXiv (arxiv.org/abs/2401.01737) and through advance access on MNRAS (academic.oup.com/mnras/advanc... ) I investigate the conditions needed to form filaments in the cold neutral medium through a periodic turbulent box simulation.

Star formation takes place in filamentary molecular clouds which arise by physical processes that take place in the cold, neutral medium (CNM). We address the necessary conditions for this diffuse...

Wow omg Anna worm food frogs4girls just like totally gets it, a revolutionary author of our time. Can't believe crusty joker rolling would steal from such a generous mind

In theory, getting bluesky sounded great. In practice, it's like going into high school where you've got friends but you're not sure if you were good enough friends to ask to sit with them at lunch.
