How to Explore Fast Radio Bursts 3D Explorer
Open Fast Radio Bursts 3D Explorer, pick a real burst source with the source slider, and watch a millisecond pulse travel from a distant host-galaxy marker to an Earth/CHIME receiver marker while a live waterfall canvas plots its dispersion sweep.
- Open https://freetoolonline.com/space-3d/fast-radio-bursts.html and wait for the host-galaxy marker, the Earth/CHIME receiver marker, and the waterfall canvas to render.
- Use the Source slider to pick Lorimer Burst (2007), FRB 121102, or FRB 180916.J0158+65.
- Click "Play Burst" and watch the millisecond pulse travel toward Earth, staggered by a teaching dispersion delay so higher radio frequencies arrive first.
- Watch the frequency-vs-time waterfall canvas plot each arriving channel as a dot, forming the classic downward dispersion-sweep signature.
- Read the facts panel for the selected source's duration, dispersion measure, and discovery details, plus the CHIME telescope band (400-800 MHz) and the SGR 1935+2154 Galactic-FRB link.
- Pick a different source on the slider and click "Play Burst" again to compare sweep speeds.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
