NASA’s IXPE Reveals X-ray-Generating Particles in Black Hole Jets
- NASA's IXPE, in collaboration with other telescopes, has uncovered how X-rays are generated in a blazar, attributing the emission to interactions between fast-moving electrons and photons.
- The study, soon to be published in Astrophysical Journal Letters, revealed that electron-photons interactions lead to X-ray production within the extreme environment of a black hole.
- IXPE's ability to measure polarization played a key role in determining that electrons, not protons, are responsible for generating X-rays in black hole jets.
- Compton Scattering, a process where electrons interact with photons, was identified as the mechanism behind X-ray emission in the blazar BL Lacertae.
- The observation of BL Lac by IXPE and ground-based telescopes provided valuable insights, with optical polarization reaching a record high of 47.5%.
- The team found that X-rays from BL Lac were less polarized than optical light, confirming electron-photons interactions as the X-ray source.
- This discovery by IXPE has shed light on a longstanding mystery surrounding supermassive black hole jets and emphasized the significance of Compton scattering in X-ray generation.
- IXPE's success in solving this mystery has been lauded by scientists involved in the project, marking a significant contribution to astrophysical research.
- Future research on blazars aims to identify more of these objects and unravel their dynamic nature, which often presents surprises.
- NASA's IXPE mission, a joint effort with the Italian Space Agency, continues to provide groundbreaking data on celestial objects and phenomena.

James Webb hunts for a haze-less exoplanet to answer longstanding mystery
- The James Webb Space Telescope is uncovering details about sub-Neptune exoplanets for the first time, which are smaller than ice giants like Neptune but with a gas composition similar to Saturn or Jupiter.
- Astronomers used Webb to study the sub-Neptune planet TOI-421 b, known for its extreme heat of around 1,340 degrees Fahrenheit, making it easier to observe due to the lack of haze in its atmosphere.
- The researchers found water vapor and large amounts of hydrogen in the planet's atmosphere, as well as carbon monoxide and sulfur dioxide, but surprisingly no methane or carbon dioxide, leading to questions about the planet's formation and uniqueness.
- This study opens up new possibilities for studying sub-Neptunes and accelerating our understanding of these planets, with the hope to observe more to unlock further insights. The research is published in The Astrophysical Journal Letters.
