Thank you for your response! I do not have a particular meaning in mind for the first name (at least not in Na'vi). All the names are either plays on my favorite animal, the okapi, with letter changes ("p" was changed to "n") or my real name, Hannah. For the last name I just combined vitra and ioang and the mother's name is just a play on my own mom's name.

UC Riverside study offers an explanation for dark matter distribution in a massive quiescent galaxy
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because JWST-ER1g acts as a lens and bends light from a distant source, which then appears as a ring — a phenomenon called strong gravitational lensing, predicted in Einstein's theory of general relativity.
The total mass enclosed within the Einstein radius — the radius of the Einstein ring — has two components: stellar and dark matter components.
"If we subtract the stellar mass from the total mass, we get the dark matter mass within the Einstein radius," said Hai-Bo Yu, a professor of physics and astronomy at the University of California, Riverside, whose team has published new work about JWST-ER1g in the journal The Astrophysical Journal Letters. "But the value for the dark matter mass seems higher than expected. This is puzzling. In our paper, we offer an explanation."
A dark matter halo is the halo of invisible matter that permeates and surrounds a galaxy like JWST-ER1g. Although dark matter has never been detected in laboratories, physicists are confident dark matter, which makes up 85% of the universe's matter, exists.
"When ordinary matter — pristine gas and stars — collapses and condenses into the dark matter halo of JWST-ER1g, it may be compressing the halo, leading to a high density," said Demao Kong, a second-year graduate student at UCR, who led the analysis. "Our numerical studies show that this mechanism can explain the high dark matter density of JWST-ER1g — more dark matter mass in the same volume, resulting in higher density."
According to Daneng Yang, a postdoctoral researcher at UCR and co-author on the paper, JWST-ER1g, formed 3.4 billion years after the Big Bang, provides "a great chance to learn about dark matter."
"This strong lensing object is unique because it has a perfect Einstein ring, from which we can obtain valuable information about the total mass within the Einstein radius, a critical step for testing dark matter properties," he said.
Launched on Christmas Day in 2021, NASA's JWST is an orbiting infrared observatory. Also called Webb, it is designed to answer questions about the universe. It is the largest, most complex, and powerful space telescope ever built.
"JWST provides an unprecedented opportunity for us to observe ancient galaxies formed when the universe was young," Yu said. "We expect to see more surprises from JWST and learn more about dark matter soon."
The study was supported by the John Templeton Foundation and the U.S. Department of Energy.
The title of the open access research paper is "Cold Dark Matter and Self-interacting Dark Matter Interpretations of the Strong Gravitational Lensing Object JWST-ER1."

Fan fiction / Re: Artreon.... eine Geschicht...
Last post by Artreon - Today at 09:53:11 AMdanke für eure Rückmeldungen bisher...
interessanterweise kam einiges zum vorletzten kapitel mit den ilus, das hat wohl den einen oder anderen berührt...
Danke,dafür, das freut mich. Genau so sollte es wirken.
Auch wenn dieses Kapitel wie ein monolithisches Denkmal für meine schreiberische Grausamkeit als Autor in der Geschichte zu stehen scheint, ist es doch weit mehr. Es ist ein wichtiger Wendepunkt, der die zukünftige Storry erst so richtig anschiebt. (Ja , es ist bisher nicht allzu storrylastig ;-) )
sicherlich habe ich mir bisher viel Zeit genommen, die Karakter vorzustellen, die Stimmungen einzufangen.
-Und vielleicht auch ein wenig die Sinnlosigkeit des ganzen Konfliktes, für den einzelnen. Denn das sind Kriege meistens, für den Einzelnen.
Die Storry wired jetzt ein bischen zulegen versprochen....
liebe Grüsse ; Artreon
