that active supermassive black holes play a key role in shaping star formation across their host galaxies. Active Galactic Nuclei May Foster Rather Than Hinder Star Formation A new investigation into nine nearby galaxies suggests that supermassive black...

refueled by cosmic gas flowing inward and metal-rich winds blowing outward from supernova explosions and active galactic nuclei. Mapping this halo has historically presented a major challenge because X-ray observations can detect high-temperature gas...

CERN researchers have recreated early-universe matter using unexpectedly small atomic collisions, challenging previous assumptions about particle physics. Researchers at CERN have successfully synthesized quark-gluon plasma—an exotic state of matter...

than the Sun. When actively feeding, these giants are surrounded by thick disks of gas and dust, known as active galactic nuclei. These regions are chaotic. Stars, gas clouds, and even smaller black holes can become trapped in the disk, interacting in...

Rare star destruction reveals a wandering supermassive black hole, offering a fresh method to hunt these elusive cosmic giants. Astronomers using NASA’s Swift Observatory together with a worldwide network of telescopes have recorded a brilliant...

New calculations reveal how underground liquid scintillator detectors can hunt for relativistic dark matter particles by tracking knocked-out neutrons. Dark matter remains one of the greatest enduring mysteries in modern physics. Although astrophysical...

Further investigation using the Keck Observatory revealed strong emission lines consistent with the presence of active galactic nuclei (AGN). By measuring the redshift of both components, the team determined they share a common systemic velocity,...

hurdles in modern astrophysics. While state-of-the-art cosmological simulations rely on energetic feedback from active galactic nuclei (AGN) to match real-world galaxy populations, the exact physical coupling between a supermassive black hole and its...

galaxies cease producing stars prematurely, a phenomenon scientists have long attributed to “feedback” from active galactic nuclei. While these central engines are physically small, their energy output—channeled through relativistic jets—can...

astrophysicists. According to a 2024 study referenced by the research team, as many as 90 percent of radio-loud active galactic nuclei existing beyond a redshift of 3.5 may remain invisible to traditional ultraviolet and optical surveys. To circumvent...

also incorporated helium reionization, a secondary stage driven largely by the intense radiation emanating from active galactic nuclei. Because this process requires significantly more energy than hydrogen reionization, it serves as a critical marker of...

A star shredded far from its galaxy’s center has revealed a massive black hole, challenging our understanding of how these giants roam through space. Astronomers have uncovered a massive black hole lurking 3,500 light-years away from the center of its...

astronomers will need: Longer monitoring of NGC 3783 over months or years. Similar campaigns on many other active galactic nuclei. Detailed models that connect magnetic reconnection, flares and winds. Even with these uncertainties, the detection itself...
