Andrea Ghez. Credit: Christopher Dibble/UCLA Andrea Ghez (Caltech MS ’89, PhD ’92), the Lauren B. Leichtman and Arthur E. Levine Professor of Astrophysics at UCLA, has won the 2020 Nobel Prize in Physics for pioneering research that helped reveal a supermassive black holelurking at the center of the Milky Way galaxy. She shares […]

Artist’s impression of black hole jets. Credit: NASA/CXC/M. Weiss Some supermassive black holes launch powerful beams of material, or jets, away from them, while others do not. Astronomers may now have identified why. Using data from NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton, Germany’s ROentgen SATellite (ROSAT), the NSF’s Karl G. Jansky Very Large […]

Black holes are one the most fascinating objects in the Universe. At their surface, known as the “event horizon,” gravity is so strong that not even light can escape from them. Usually, black holes are quiet, silent creatures that swallow anything getting too close to them; however, when two black […]

Three color image showing results of an M87 simulation, red shows emission at long radio wavelengths, blue shows emission at 1.3mm (the wavelength the EHT uses), and green shows emission at 0.87 mm wavelengths.

Black hole accretion disk and torus. Credit: NASA/JPL-Caltech Matter swirling around supermassive black holes creates bursts of light that “echo” in nearby dust clouds. These traveling signals could serve as a new cosmic yardstick. When you look up at the night sky, how do you know whether the specks of […]

Insight-HXMT discovers QPO generated in the closest jet to the black hole. Credit: IHEP Insight-HXMT, China’s first space X-ray astronomical satellite, has discovered a low-frequency quasi-periodic oscillation (QPO) above 200 kiloelectron volts (keV) in a black hole binary, making it the highest energy low-frequency QPO ever found. The scientists also found that […]

Snapshots of the M87* black hole appearance, obtained through imaging / geometric modeling, and the EHT array of telescopes in 2009-2017. The diameter of all rings is similar, but the location of the bright side varies. Credit: M. Wielgus, D. Pesce & the EHT Collaboration Analysis of the event horizon […]

Magnetic reconnection is generated by the irradiation of the LFEX laser into the micro-coil. The particle outflow accelerated by the magnetic reconnection is evaluated using several detectors. As an example of the results, proton outflows with symmetric distributions were observed. Credit: Osaka University Scientists at Osaka University use extremely intense […]

ANIMATION Through simulations of a dying star, a team of theoretical physics researchers have found the evolutionary origin and the maximum mass of black holes which are discovered by the detection of gravitational waves as shown in Figure 1. The exciting detection of gravitational waves with LIGO (laser interferometer gravitational-wave observatory) and VIRGO (Virgo […]
