NASA's IXPE reveals X-ray-generating particles in black hole jets
- NASA's IXPE revealed that X-rays in the jets of blazar BL Lacertae originate from electrons scattering photons via the Compton effect in late November 2023 observations.
- This discovery addressed a longstanding debate over whether protons or electron-photon interactions cause X-ray emission in supermassive black hole jets.
- IXPE measured X-ray polarization below 7.6%, far less than the 47.5% optical polarization, confirming electron involvement through Compton scattering with support from ground-based telescopes.
- Lead author Iván Agudo explained that IXPE, alongside several complementary ground-based observatories, equipped researchers with the necessary means to resolve a significant mystery surrounding black hole jets.
- The findings, available as a preprint and to appear in Astrophysical Journal Letters, highlight IXPE's unique polarized X-ray capability and open avenues for discovering similar sources.

NASA’s IXPE Solves Mystery of X-Ray Emissions from Supermassive Black Hole
A supermassive black hole, blazar BL Lacertae, has finally revealed how these cosmic features generate X-rays, thanks to new international research using NASA’s Imaging X-ray Polarimetry Explorer (IXPE). Blazar BL Lacertae’s jets point directly toward Earth, pouring forth from the supermassive black hole surrounded by a brilliant halo, which presents an optimal condition for the scientific study of its X-rays. The new work proves that electron a…
NASA Cracks 30-Year X-ray Mystery With Blazing Black Hole Light Show
Astronomers using NASA’s IXPE satellite have finally cracked a cosmic mystery—how X-rays are produced in the energetic jets of supermassive black holes like the blazar BL Lacertae. The blazar BL Lacertae—a type of active galaxy powered by a supermassive black hole with bright, fast-moving jets ai
NASA's IXPE reveals X-ray-generating particles in black hole jets

NASA Sonification of Black Holes Preview What They Could Sound Like
NASA’s sonification of black holes turns space data into sounds to show different parts of black holes and their surroundings. This uses info from telescopes like NASA’s Chandra X-ray Observatory, James Webb Space Telescope (JWST), Imaging X-ray Polarimetry Explorer (IXPE), and others to make three cosmic soundscapes. First, there’s WR124, a huge, short-lived star about [...]
NASA Solves Black Hole Jet X-ray Mystery with IXPE’s Polarization Powers
NASA’s IXPE satellite may have solved a longstanding astrophysical mystery: how are X-rays produced in the extreme jets of supermassive black holes? By observing the blazar BL Lacertae, IXPE recorded low X-ray polarization versus very high optical polarization—confirming Compton scattering as the likely mechanism. This breakthrough supports the electron-photon interaction theory over proton-based explanations.
