Peering Into NGC 3783’s Core

Using XMM-Newton and the JAXA-led XRISM mission, scientists studied the supermassive black hole at the heart of NGC 3783, which weighs about 30 million times the Sun’s mass. As it devours surrounding material, it powers an intensely bright Active Galactic Nucleus (AGN), capable of launching powerful jets and winds across space.

“These winds appear to arise when the AGN’s tangled magnetic fields suddenly ‘untwist’—like solar flares, but on an unimaginably larger scale,” explains Matteo Guainazzi, ESA XRISM Project Scientist and co-author of the study. Figure 1 shows Black Hole Unleashes Near-Light-Speed Winds in Hours.

Black Hole Winds Mirror Solar Eruptions

The powerful winds from supermassive black holes resemble the Sun’s coronal mass ejections—enormous bursts of superheated material that shoot into space during intense solar activity. This similarity hints that black holes can sometimes behave like gigantic versions of our Sun, governed by magnetic eruptions.

“These ‘windy’ AGNs influence the evolution of their host galaxies and the formation of new stars,” explains Camille Diez, ESA Research Fellow. “Understanding AGN magnetism and how it drives such winds is crucial to piecing together the history of galaxies across the Universe.”

Twin Telescopes Capture a Rapid Cosmic Event

For over 25 years, XMM-Newton has explored the Universe’s hottest and most extreme objects, while XRISM, launched in September 2023, investigates how matter and energy flow through space. Together, they tracked a spectacular black hole flare and the ultra-fast winds that followed.

XMM-Newton used its Optical Monitor to follow the flare’s evolution and its European Photon Imaging Camera (EPIC) to measure the wind’s spread. Meanwhile, XRISM’s Resolve instrument examined the winds’ speed, structure, and driving mechanisms.

Peering into the Heart of NGC 3783

Astronomers focused on the galaxy NGC 3783, home to a supermassive black hole about 30 million times the mass of the Sun. Using XMM-Newton and XRISM, they studied the galaxy’s Active Galactic Nucleus (AGN), the intensely bright core powered by matter falling into the black hole.

The observations revealed powerful winds forming as the AGN’s tangled magnetic fields suddenly “untwisted”—a process similar to solar flares, but on a scale millions of times larger.

Cosmic Winds Echo Solar Explosions

These black hole winds resemble the Sun’s coronal mass ejections—huge bursts of superheated material that shoot into space during solar activity.

Just like solar flares influence the solar system, these AGN winds shape their host galaxies, regulating star formation and the overall evolution of the galaxy. Understanding the magnetic forces behind these winds helps scientists trace the cosmic history of galaxies.

Two Telescopes Capture a Rapid Event

XMM-Newton, with over 25 years of study, and the recently launched XRISM, worked together to monitor the flare and the fast-moving winds. XMM-Newton tracked the flare’s evolution, while XRISM measured the winds’ speed, structure, and driving forces.

Their combined observations revealed winds reaching near-light speeds in just hours—a striking demonstration that the physics governing our Sun can also operate on colossal cosmic scales.
