(Skip to the end if you want to get on a mailing list for sharing the materials we're making!)

Thank you to all who attended an early Friday talk and asked great questions! 🤩

"MPIA: Forscher identifizieren zwei der frühesten Bausteine der Milchstraße

.. Bei den „Shakti“ und „Shiva“ genannten Gebilden dürfte es sich um Überreste zweier Galaxien handeln, die vor 12 bis 13 Milliarden Jahren mit einer frühen Version der Milchstraße verschmolzen und so zum frühen Wachstum .. beitrugen. Eine Pressemitteilung des .. MPIA."

By using public data from the #SDSS, #researchers have analyzed the #kinematics of #satellitepairs around #massivegalaxy groups. Findings suggest that the #universe may be younger than predicted by the #LCDM model with #Planck #cosmologicalparameters.

Great paper by Mirjam Guesgen for @Motherboard @VICENews on the discovery of the Big Ring

On the proximity of this structure with the Giant Arc:
“Identifying two extraordinary ultra-large structures in such close configuration raises the possibility that together they form an even more extraordinary cosmological system.” @morninglopez (co-author of the discovery)

I'm excited to present at the Spatial Data Science Symposium coming up this week! I've written up the content of the presentation for anyone interested in learning more https://shriv.github.io/sdss-2023/

Finally: #SDSS plates for education! The SDSS plates are getting a new life in schools. My #MaterialCulture heart is sooooooo happy #NAM2023 #Astronomy #SciComm #PublicEngagement

Just finished adding support for texture arrays in particle cloud objects. This is what SDSS looks like when adding a texture array with ~30 random galaxies.

Check out this interactive 3D #map of a ~1 Gpc^3 volume of the #universe: https://skfb.ly/6RyGE
It was created by analyzing the Lyman-alpha absorption lines of the light emitted by distant #quasars, using data collected by the #SDSS Sloan Digital Sky Survey / eBOSS Extended Baryon Oscillation Spectroscopic Survey.
