Visualizations

The following is a collection of visualizations produced from AbacusSummit data. These images may be used under the CC-BY-4.0 license, with attribution to “The AbacusSummit Team”.

Video: “Many Universes”

With AbacusSummit, we simulate many possible universes that are slight variations of each other. This video shows nearly 100 of those universes, transitioning smoothly between them by interpolating the positions of individual particles.

A few different resolutions and aspect ratios are available for download:

1080p (16:9 aspect)

Full-width HD, good for a full (widescreen) slide: Download (340 MB)

1080p (7:6 aspect)

Narrow HD, good for half a slide (or a 4:3 slide): Download (270 MB).

1440p (16:9 aspect)

Full-width QHD, this is the best version to use on a high-resolution computer monitor: Download (740 MB)

1920p (45:32 aspect)

Very high resolution, narrow aspect, with the plot elements slightly rearranged to allow space at the bottom for a caption (displayed on the visualization wall in the Flatiron Institute lobby): Download (1.2 GB)

The source code for the scripts used to generate these videos is here: https://github.com/lgarrison/manyuniverses-viz

The videos are VP9-encoded, so you may need a relatively modern video player or web browser to play them. The bitrate is also fairly high, so you probably need GPU-accelerated video decoding for the video to play smoothly. They probably won’t look good over Zoom or most screen-sharing software because there’s so much motion and fine detail, but they should look good when directly displayed on a screen or projector.

Phase-sheet Evolution

_images/lattice_memory_multi.png

A single cutout of a Lagrangian plane—a square from a particle plane selected in the initial conditions—at redshifts \(z=2.5\), \(z=1.1\), \(z=0.1\) from the highbase simulation. The “memory” of the initial lattice configuration persists to low redshift in low-density regions. Download here: PNG (725 KB).

Phase-matching test

A visualization of the same halo at two different mass resolutions. Try opening both of these images and blinking back and forth between them!

Same halo, two cosmologies

_images/AbacusSummit_base_c004_ph000_halo_zoom.png

A visualization of the same halo in c000 (the base cosmology) and c004 (low sigma8 cosmology). Try opening both of these images and blinking back and forth between them!
