Info on the supernova accelerating space Nobel prize.

AI Thread Summary
The discussion centers on the findings related to Type Ia supernovae and their redshifts, which suggest that the universe is expanding at an accelerated rate. Participants seek detailed interpretations of the research that led to the Nobel Prize in Physics, particularly the original paper by Perlmutter et al. The conversation emphasizes the need for more in-depth resources beyond superficial media coverage. A reference to Sean Carroll's FAQ on dark energy is provided as a potential resource for further understanding. The thread aims to compile comprehensive insights and relevant academic citations on this significant astrophysical discovery.

In this thread I would like you to add some more detailed information on what the people behind the new physics prize have actually found, what the interpretation is and where the relevant papers are.

The redshifts of supernovaes of type 1a are redshifted in some peculiar way that is interpretated as the universe is expanding at an accelerated pace? From wikipedia and media I only seem able to gain some very superfiscial information...
 
Space news on Phys.org
See the original paper by Perlmutter, et al, [http://arxiv.org/abs/astro-ph/9812133] on arxiv then follow the citations.

Sean Carroll recently put up a FAQ which might interest you:

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##.
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...
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...
