An Ultra-Faint, Chemically Primitive #Galaxy Forming in the Reionization Era: https://arxiv.org/abs/2506.11846 -> Astronomers Find Most Chemically Primitive Galaxy in Early Universe / Clues to the Mysterious Origins of Ultra-Faint Dwarfs: https://www.nao.ac.jp/en/news/science/2026/20260514-dos.html / https://www.kanazawa-u.ac.jp/en/miraichi/183006/ / https://www.icrr.u-tokyo.ac.jp/en/news/17894/

The #Hubble #Arp #Galaxy Survey: https://iopscience.iop.org/article/10.3847/1538-4365/adfc67 -> "We present new optical F606W images and point-source photometry for 216 systems, whose sizes are well matched to the Advanced Camera for Surveys’ wide field of view. Essentially, none of the samples had been previously observed with Hubble. The resulting images display rich morphologies, revealing a variety of massive stars, H ii regions, stellar clusters, dust lanes, tidal tails, backlit galaxies, and occasional chance superpositions" -> interview with the first author: https://www.youtube.com/watch?v=eewSudl4w34

A massive and evolved slow-rotating #galaxy in the early Universe: https://arxiv.org/abs/2508.10987 -> Non-Rotating Early Galaxy Is a Surprise to Astronomers: https://www.ucdavis.edu/news/non-rotating-early-galaxy-surprise-astronomers

"We’re delighted to announce the first #GalaxyZoo workflow to include images from the NSF-DOE Vera C #Rubin Observatory, using #galaxies drawn from its first Data Preview": https://blog.galaxyzoo.org/2026/05/12/a-first-galaxy-zoorubin-project/ - "[t]he new workflow went live on the site just now, but with only 10,359 subjects it won’t stick around for long, so do jump in and get classifying."

JWST observes the assembly of a massive #galaxy at z~4: https://arxiv.org/abs/2511.13650 -> "NIRCam images and NIRSpec/IFU spectroscopy (R=2700) show that TGSSJ1530 1049 is part of one of the densest-known structures of continuum and line-emitting objects found at these redshifts. [...] Based on the physical separations and velocity differences between the galaxies, it is expected that these galaxies will merge to form a massive galaxy within a few Gyr. The system qualitatively resembles the forming brightest cluster galaxies in cosmological simulations that form early through a rapid succession of mergers."
