An article published in "The Astrophysical Journal" reports the results of a study of dust generated by red giant stars towards the end of their lives under conditions similar to those existing in the first galaxies of the universe. A team of researchers lused observations conducted with the James Webb Space Telescope to study the Sextans A dwarf galaxy, where the environment is very metal-poor.

🌟🔭The #HRMOS Science White Paper is out:
https://arxiv.org/abs/2312.08270
The High-Resolution Multi-Object Spectrograph (HRMOS) is a new facility instrument that will be proposed for the #VLT of #ESO
HRMOS will have high spectral resolution (R = 60000 - 80000), multi-object (20-100) capability, and excellent radial velocity stability (10m/s).

Milky Way will probably devour all the tiny #galaxies that surround it
Based on data from #ESA's Gaia mission, it was found that many dwarf galaxies that were orbiting #MilkyWay only a few BYA have ended up destroyed after being pulled in by our much more massive galaxy. It is possible #darkmatter has something to do with this. By identifying galactic remnants, they determined that most #dwarfgalaxy remnants within the Milky Way only entered it within the last 3B yr or so

And here is what a quick reduction of a #Keck echelle spectrum looks like, with the sky emission taken out: this is from a #DwarfGalaxy in the #VirgoCluster observed earlier tonight; the interest here is in the absorption lines.

#astronomy #DwarfGalaxy #Peekaboo
An article accepted for publication in the journal "Monthly Notices of the Royal Astronomical Society" reports a study of a dwarf galaxy cataloged as HIPASS J1131–31 that is relatively close but has the characteristics of a primordial galaxy. They nicknamed it Peekaboo because it peeks out from behind a bright star that hid it for a long time and made it difficult to identify.

@coreyspowell When a #SpiralGalaxy is approached by a much smaller companion, such as a #DwarfGalaxy, the larger #Galaxy's uneven gravitational pull will start to severely distort the smaller star system. Over the course of a few billion years, tendril-like structures develop.
