A new Northwestern University-led study is changing the way astrophysicists understand the eating habits of supermassive black holes.

This NASA illustration shows the structure of a black hole jet as inferred by recent observations of the blazar Markarian 421 by the Imaging X-ray Polarimetry Explorer (IXPE). The jet is powered by an accretion disk, shown at the bottom of the image, which orbits and falls into the black hole over time. Helical magnetic fields are threaded through the jet. IXPE observations have shown that the X-rays must be generated in a shock originating within material spiraling around the helical magnetic fields. The inset shows the shock front itself. X-rays are generated in the white region nearest the shock front, whereas optical and radio emission must originate from more turbulent regions further away from the shock.

New IXPE Blazar Findings

Artistic illustration of OJ287 as a binary black hole system. The secondary black hole of 150 million solar masses moves around the primary black hole of 18 billion solar masses. A disk of gas surrounds the latter. The secondary black hole is forced to impact on the accretion disk twice during its 12-year orbit. The impact produces a blue flash which was detected in February 2022. In addition, the impact also induces the secondary black hole to bright bursts of radiation several weeks earlier, and these bursts have also been detected as a direct signal from the secondary black hole.
