The third #AAS247 presser https://www.youtube.com/watch?v=hfDmYXvBbV4 about News from the High-Redshift Universe and Local Analogs dealt with the papers The ALPINE-CRISTAL-JWST Survey: JWST/IFU Optical Observations for 18 Main-sequence Galaxies at z = 4–6 (https://iopscience.iop.org/article/10.3847/1538-4365/ae0928 with https://www.caltech.edu/about/news/young-galaxies-grow-up-fast and https://public.nrao.edu/news/young-galaxies-grow-up-fast/), A New Population of Point-like, Narrow-line Objects Revealed by the James Webb Space Telescope (https://arxiv.org/abs/2509.12177 with https://showme.missouri.edu/2026/scientists-discover-platypus-galaxies-in-the-early-universe/ and https://science.nasa.gov/missions/webb/scientists-identify-astronomys-platypus-with-nasas-webb-telescope/; slide), Supermassive Stars Match the Spectral Signatures of JWST's Little Red Dots (https://arxiv.org/abs/2507.12618 with https://www.cfa.harvard.edu/news/scientists-use-jwst-examine-ancient-monster-stars-may-reveal-birth-black-holes) and Discovery of SiC and Iron Dust around AGB Stars in the Very Metal-poor Sextans a Dwarf Galaxy with JWST: Implications for Dust Production at High Redshift & JWST Captures Growth of Aromatic Hydrocarbon Dust Particles in the Extremely Metal-poor Galaxy Sextans A (https://iopscience.iop.org/article/10.3847/1538-4357/adf06a / https://arxiv.org/abs/2512.04060 with https://science.nasa.gov/missions/webb/nasa-webb-finds-early-universe-analogs-unexpected-talent-for-making-dust/).

RE: #redshift measured spectroscopically hailed in this press release as well as in https://esawebb.org/news/weic2603/ and https://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_gazes_further_back_in_time has been published in May 2025 as https://arxiv.org/abs/2505.11263 (appearing on ArXiv counts as a publication in today's academic landscape) and made some headlines then, including by yours truly: https://skyweek.wordpress.com/2025/05/18/resiliences-mond-punch-fur-alle-pslv-versagt/ ("Neuer spektroskopischer Rotverschiebungs-Rekord: z=14.44").

Sunyaev–Zeldovich detection of hot intracluster gas at redshift 4.3: #GalaxyCluster in the early universe is 10 times hotter than it ought to be, which may reshape how we think these enormous structures formed.

A 15 Mpc rotating #galaxy filament at redshift z = 0.032: https://academic.oup.com/mnras/article/544/4/4306/8363602?login=false -> 'Teacup-like' spinning structure one of largest ever seen in universe: https://ras.ac.uk/news-and-press/research-highlights/teacup-spinning-structure-one-largest-ever-seen-universe

The 6th #AAS247 press conference https://www.youtube.com/watch?v=nss3zNi5SYA about Cosmology and Galaxy Clusters discussed the lensed supernova Ares from the Vast Exploration for Nascent, Unexplored Sources (VENUS) program (https://www.stsci.edu/jwst-program-info/download/jwst/pdf/9478/), the paper PASSAGES: The Discovery of a Strongly Lensed Protocluster Core Candidate at Cosmic Noon (https://iopscience.iop.org/article/10.3847/1538-4357/adf4d5 with https://public.nrao.edu/news/cosmic-lens-reveals-hyperactive-cradle-of-future-galaxy-cluster/), new results from the One-hundred-deg^2 DECam Imaging in Narrowbands (ODIN) survey (https://iopscience.iop.org/article/10.3847/1538-4357/ad165e) and the paper Sunyaev–Zeldovich detection of hot intracluster gas at redshift 4.3
