NASA Solves Black Hole Jet Angle Mystery with Chandra Observatory
NASA’s Chandra X-ray Observatory has made a breakthrough in accurately determining the angles of black hole jets, a critical step in understanding these enigmatic cosmic phenomena. The discovery, involving two quasars about 11 billion light-years away, sheds new light on black hole behavior and their influence on galaxy formation.
Revolutionizing Black Hole Research
The accurate measurement of jet angles was hindered by significant errors, where even weak emissions directed towards Earth appeared misleadingly bright. Similar to observing through a lens, this skewed our understanding of a jet’s true power and trajectory.
Scientists from NASA have tackled this problem using data from the Chandra Observatory, focusing on the cosmic noon period—an era marked by accelerated galactic and black hole development. The influence of jets on galaxy formation is twofold: they drive gas away from galactic centers while also spurring star formation on the periphery.
Game-Changing Methodology
One of the examined jets, seemingly brighter near its origin, revealed that cosmic microwave background radiation intensified its energy, converting it into the X-ray energy band. The high density of microwave photons during that epoch propelled the particles faster, offering a new perspective on jet dynamics.
The study presented a statistical method that evaluates how relic radiation impacts relativistic jets, pushing particles to speeds between 92-99% of light. This innovative approach allowed for precise determination of jet angles relative to Earth for the discovered pair, pinpointed at approximately 9 and 11 degrees. The method promises to correct systematic errors in existing catalogs dominated by Earth-facing jets.
This advancement not only enhances the accuracy of astronomical data but also deepens our understanding of black holes and their pivotal role in shaping the universe.
