Introducing the yt Hub
@ Britton Smith | Wednesday, Aug 24, 2011 | 2 minute read | Update at Wednesday, Aug 24, 2011

I am very excited to announce the yt Hub: http://hub.yt-project.org/.

The yt Hub is a gathering place for all things related to running, analyzing, and presenting astrophysical simulations. Once upon a time, we had the Enzotools Barn, which was a place to share Enzo scripts unrelated to yt, including hosting of those scripts. The Barn was a minor success, but had a very limited scope and a somewhat clunky user experience.

Now we have the yt Hub, where users can submit externally- hosted projects in a variety of categories:

  • yt scripts
  • Analysis and visualization tools and utilities
  • Simulation and data management
  • Scripts for making figures from published papers
  • News and announcements
  • General astrophysical utilities

Users can create their own accounts and share anything they’ve created that might be useful to others. Currently, the preferred submission method is to create a repository on bitbucket.org and then submit the link to that. If you would like to host the repository for your contribution somewhere else, that’s fine, too. The forthcoming 2.2 release of yt will include a utility for automating the creation and uploading of a bitbucket.org repository as well as submitting that repository to the Hub.

In addition, users may also subscribe to email announcements, in which they will receive an email with any new submissions from the previous day.

Please, come check it out and contribute. The site is brand new, so feel free to send feedback if you encounter any oddities or think of improvements. The primary goal of yt has been to create a common analysis language for computational astrophysicists coming from different simulation codes. We hope that the yt Hub will serve as the meeting place for the conversation.

yt extension modules

yt has many extension packages to help you in your scientific workflow! Check these out, or create your own.

ytini

ytini is set of tools and tutorials for using yt as a tool inside the 3D visual effects software Houdini or a data pre-processor externally to Houdini.

Trident

Trident is a full-featured tool that projects arbitrary sightlines through astrophysical hydrodynamics simulations for generating mock spectral observations of the IGM and CGM.

pyXSIM

pyXSIM is a Python package for simulating X-ray observations from astrophysical sources.

ytree

Analyze merger tree data from multiple sources. It’s yt for merger trees!

yt_idv

yt_idv is a package for interactive volume rendering with yt! It provides interactive visualization using OpenGL for datasets loaded in yt. It is written to provide both scripting and interactive access.

widgyts

widgyts is a jupyter widgets extension for yt, backed by rust/webassembly to allow for browser-based, interactive exploration of data from yt.

yt_astro_analysis

yt_astro_analysis is the yt extension package for astrophysical analysis.

Make your own!!

Finally, check out our development docs on writing your own yt extensions!

We welcome contributions from all members of the yt community. Feel free to reach out if you need any help.

the yt data hub

The yt hub at https://girder.hub.yt/ has a ton of resources to check out, whether you have yt installed or not.

The collections host all sorts of data that can be loaded with yt. Some have been used in publications, and others are used as sample frontend data for yt. Maybe there’s data from your simulation software?

The rafts host the yt quickstart notebooks, where you can interact with yt in the browser, without needing to install it locally. Check out some of the other rafts too, like the widgyts release notebooks – a demo of the widgyts yt extension pacakge; or the notebooks from the CCA workshop – a user’s workshop on using yt.
