Resolved Magnetic Fields Near Sgr A*
We have just published our first polarization results using the Event Horizon Telescope! We detected ordered magnetic fields near the event horizon of our Galactic Center supermassive black hole, Sagittarius A*, and we found clear signatures of magnetic turbulence. These results clarify two peculiar properties of supermassive black holes: how they pull matter inward so efficiently and why they are so bright.
You can read our paper on Science or arXiv. You can watch a short talk I gave explaining these results here (aimed toward an audience of professional astronomers).
Here is some coverage of our results:
- Science Magazine news release
- Sky and Telescope
- Dark Star Diaries (a Scientific American blog)
- Official CfA Press Release
- Physics World
- Washington Post
- Science Alert
Here's a terrific cartoon explaining how the Event Horizon Telescope can tell us about magnetic fields near a black hole that's 26,000 light years away:
