An artist’s concept illustrates a supermassive black hole. Credit: NASA/JPL-Caltech A new study has developed an innovative method to detect colliding supermassive black holes in our Universe. The study has just been published in the Astrophysical Journal and was led by postdoctoral researcher Xingjiang Zhu from the ARC Centre of Excellence for Gravitational […]

Numerical simulation of two black holes that inspiral and merge, emitting gravitational waves. The black holes have large and nearly equal masses, with one only 3% more massive than the other. The simulated gravitational wave signal is consistent with the observation made by the LIGO and Virgo gravitational wave detectors […]

The center of quasar 3C279 emits flickering gamma radiation, which is characteristic of the phenomenon of magnetic reconnection.

Two astrophysicists share this discovery in the journal Nature Communications. […]

ANIMATION A new study reveals what happens when a supermassive black hole in the center of a galaxy cluster stops being active. By combining data from Chandra, Hubble, and Spitzer data, astronomers found a deluge of star formation in the cluster known as SpARCS1049. SpARCS1049 is producing stars at a rate some […]

ANIMATION Astronomers have discovered what can happen when a giant black holedoes not intervene in the life of a galaxy cluster. Using NASA’s Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior may explain a remarkable torrent of star formation occurring in a distant cluster of galaxies. […]

ANIMATION Scientists from the University of Valencia detect rapid changes in ablack hole that may help understand the origin of gamma-ray bursts. A team from the Astronomical Observatory of the University of Valencia has managed to observe the black hole of the active galaxy PKS1830-211 right during the most violent gamma-ray […]

An artist’s impression of the quasar Pōniuāʻena. Astronomers discovered this, the second most distant quasar ever found, using the international Gemini Observatory and Cerro Tololo Inter-American Observatory (CTIO), Programs of NSF’s NOIRLab. It is the first quasar to receive an indigenous Hawaiian name. In honor of its discovery from Maunakea, […]

This diagram shows how a shifting feature, called a corona, can create a flare of X-rays around a black hole. The corona (feature represented in purplish colors) gathers inward (left), becoming brighter, before shooting away from the black hole (middle and right). Astronomers don’t know why the coronas shift, but […]

Credit: CC0 Public Domain Scientists at Harvard University and the Black Hole Initiative (BHI) have developed a new method to find black holes in the outer solar system, and along with it, determine once-and-for-all the true nature of the hypothesized Planet Nine. The paper, accepted to The Astrophysical Journal Letters, highlights […]
