Hyperion Proto-supercluster

Post #1by **Anthony_B_Russo10** » 02.08.2019, 07:04

This adds a representation of the Hyperion Proto-supecluster comparing it to the local super cluster. It is represented as a galaxy due to Celestia limits and it is impossible to get a good view due to galaxy render limits. It's not visible, to view it open the dsc file with a generic text editor and and set the false values to true.

Speaking of Galaxy Clusters and Superclusters, would it be possible for the developers to make a galaxy group/cluster and supercluster barycenter that would serve as the identity of the supercluster, and then perhaps make the galaxies move in such a way that they will eventually merge with one another, based on their current measurements?

It's on my list next to astrodb branch.

Galaxy impacts are calculated on huge computation clusters, how do you imaging this work done on a commodity PC?

He's talking about presentation, not calculation, I think :wink:

It doesn't have to be fully accurate, seeing that we're predicting the future with it. I think IllustrisTNG might give us a basic idea of how we can predict galaxy collisions and mergers. However, what would be more important to me is the creation of barycenters for clusters and superclusters, so that they can have their own identities, and perhaps increasing inherent galaxy brightness would be a good improvement as well, because currently, the galaxies in Celestia look too dim, even if it's covering up the whole screen, and the actual galaxies are bright and have several beautiful colors and designs. I think there are a few mods that make them bright or colorful.

I always thought galaxies in Celestia were much too bright. The "pretty picture" images that you're invoking are long-exposure images, rather than anything remotely close to what the human eye sees.

Only the very centre of the Andromeda Galaxy is visible to the naked eye from Earth, nothing more.

Speaking of Superclusters and Galaxy movements, this could be of help: http://www.ifa.hawaii.edu/info/press-releases/local_void/

And the Cosmicflows-3 Galaxy compendium could be of good use as well: arxiv.org/abs/1605.01765
