AI Thread Summary
The discussion centers on a hypothesis suggesting that anomalous ionization near galactic centers is caused by dark matter particles colliding to create electron-positron pairs, potentially leading to detectable gamma rays. Participants inquire about relevant research papers, with links provided to both a published paper and a free version. There is a consensus on the need for further investigation to determine if the hypothesis holds true. The conversation emphasizes the significance of next-generation telescopes in confirming these findings. Overall, the exploration of dark matter's role in cosmic phenomena continues to generate interest and debate.

The hypothesis is that the anomalous ionization noticed near galactic centers is due to dark matter particles colliding to make an electron and positron. This would produce distinctive gamma rays detectable by the next generation of telescopes.

 
Space news on Phys.org
Is there a link to a paper somewhere in that video?
 
Ok - too much particle physics in that for me.

I guess we'll see if it pans out.

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo".'

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...

Thread 'Big Bang and Infinite Universe'

Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
