Many years ago I registered the astro-ph.co domain because it got turned into a link by various email clients (and even PDF readers) - and I thought it would be useful if rather than dumping you at a "no such domain" error page or a search engine result page, it actually took you to the relevant arXiv page. I never got around to doing more than a simple redirect to https://arxiv.org/list/astro-ph.CO/recent but I hope that's been better than nothing.

Anyway, I've now renewed it for one more year, and because .co domains are relatively expensive and I can't even really remember the problem I was trying to solve with this, I'm going to let it lapse in September 2025. In the meantime, if anyone has any responsible ideas for what to do with this and wants to take it over, let me know.

I'll probably boost/repost about this …

An article published in the journal "The Astrophysical Journal" reports the results of a study on the ongoing merger between two galaxy clusters that are forming a single new cluster, MACS J0018.5+1626. A team of researchers used data obtained from observations dating back even decades conducted with various space and ground-based telescopes, analyzing them to decouple the behavior of ordinary matter and dark matter.

“In Baka cosmology all elements of the environment are interconnected. The forest is listening to its inhabitants, and vice versa. Forest sounds are very diverse and polyphonic. So are Baka conversations with the forest. The song is a communication with the forest. The polyphonic sounds are the language of the forest. The myriads of creatures calling into the night give enough space in their calls so that all can be heard. The overall Kaleidoscope of sound is a real-time representation of what is going on at that precise moment. Any changes are reflected in the sounds. All sentient beings reacting to the sounds and silences of the others. This is the voice of the rainforest that tells you everything you need to know, and being part of this soundscape enables you to affect what happens.”

The , JADES-GS-z14-0 was determined to be at a redshift of 14.32, making it the current record-holder for the most distant known galaxy.

This corresponds to a time less than 300 million years after the big bang.

The galaxy is several hundreds of millions of times the mass of the Sun!

This raises the question: How can nature make such a bright, massive, and large galaxy in less than 300 million years?

The NIRCam data was used to determine which galaxies to study further with spectroscopic observations. One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.32 (+0.08/-0.20), making it the current record-holder for the most distant known galaxy. This corresponds to a time less than 300 million years after the big bang.
