Any kindred spirits? My research involves writing and using a lot of cosmology code and I was just wondering if their was anyone else on the forum up to their elbows in Gadget2 code (or any other cosmo codes).
 
Space news on Phys.org
i'm working on decomposing and learning NChilada. Hows gadget? Some people use it at my school.

Currently though I'm trying to build my own =]
 
Hi neurocomp! I am trying to write my own too, but I figured id use the Gadget 2 format for the inputs. Mine will be a post processing radiative transfer code. A person could use a series of Gadget snapshots and ray trace through the SPH field to get some idea about ionized regions. What kind of code are you writing?
 
attempting generalized N-body science code. focus on astrophysics and rendering.
 

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...
