When to Use the Relativistic Jets & Doppler Beaming 3D Explorer - Best Sessions and Limits

Last reviewed: 2026-07-24

Open this explorer when you want to see why a black hole's jet looks one-sided from Earth, or to teach Doppler beaming and apparent superluminal motion with the real M87 numbers - not to run a magnetohydrodynamic jet-launching simulation.

A beaming lesson

A lesson starts at the reset baseline (no beaming) to see two equally bright jets, then loads the "M87" preset to watch one jet brighten and the other all but disappear, reading the computed Doppler factor and apparent speed off the facts panel at each step.

Sessions this explorer does not fit

Sessions this page does not fit are exploring the exact Kerr photon-orbit and ISCO geometry - use the Photon Sphere & ISCO 3D Explorer for that - or viewing an artistic accretion-disk glow with no beaming physics - use the Black Hole 3D Explorer. Walk the controls in the step-by-step guide.

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.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
