High-velocity #MolecularClouds in M83: https://iopscience.iop.org/article/10.3847/1538-4357/addab7 -> Milky Way-like galaxy M83 consumes high-speed clouds: https://www.u-tokyo.ac.jp/focus/en/press/z0508_00416.html & https://news.stonybrook.edu/university/research-provides-new-insight-into-how-galaxies-evolve-over-time/ - unusually fast clouds of gas around nearby galaxy suggest extragalactic origin.

An article published in "The Astrophysical Journal" reports a study of 17 molecular clouds in the Small Magellanic Cloud, one of the Milky Way's satellite dwarf galaxies. A team of researchers examined high-resolution images captured using the ALMA radio telescope to obtain information on their characteristics. The examination showed that 40% of those clouds had a more diffused gas, with fluffy structures.

Rapid Growth of Galactic Supermassive #BlackHoles through Accreting Giant #MolecularClouds during Major Mergers of Their Host #Galaxies: https://iopscience.iop.org/article/10.3847/1538-4357/acd841 -> Unveiling the Rapid Growth of Supermassive Black Holes: https://press.asiaa.sinica.edu.tw/ASIAA_TAIWAN_News/230621

This is a very neat result: using ALMA, a team surveyed 39 massive cosmic clouds, or "star nurseries”… and found in the order of ~800 stellar seeds… and 99% of them lacked the mass to give birth to massive stars. It seems that core density might be more critical than mass for high-mass star formation than previously thought.
