Black holes

The Wolf Prize in Physics for 2024 is awarded to Professor Martin Rees of the University of Cambridge, England, for his "pioneering contributions to high-energy astrophysics, the formation of galaxies and structures in the universe, and cosmology"
Two black holes orbit each other but usually only see the jet of one of them A rare observation made it possible to see the other as well and provide new insights
A soon-to-be-launched novel space telescope may reveal a new type of "featherweight" black hole that will challenge existing theories of black hole formation
Fifty years ago, physicist Stephen Hawking proposed that dark matter might be a population of black holes, which may have formed shortly after the Big Bang. They also existed for a short time but had an impact on
First-ever model simulations of individual stars in a star cluster in the process of formation suggest possible mechanisms for the formation of intermediate-mass black holes
Observing the universe using gravitational waves poses significant technological challenges, especially in the investigation of the frequency range above one kilohertz, the astronomers are technologically assisted in the magnetosphere of planets to detect the gravitational waves
Researchers have developed a method for mapping the central regions around black holes, which contributes to a better understanding of their growth
A NASA astrophysicist has developed immersive simulations of a black hole using a supercomputer. These visuals illustrate two scenarios: a last-minute escape or crossing the event horizon and falling into the black hole
The analysis of the signal GW230529 picked up by LIGO shows that it originated from the merger of two compact objects, one with a mass between 1.2 and 2.0 times that of the Sun and the other with a mass slightly more than twice the first
A new study reveals details of an unknown class of galaxies called compact compact objects (CSOs) that emit jets moving in opposite directions at speeds close to the speed of light
A new study, led by the UK's University of Bath, has found that supermassive black holes need both merging galaxies and cold gas to grow. This discovery, obtained through machine learning, may change our understanding of
Data from the Gemini North Telescope provide a possible explanation for the halting of the merger of a pair of supermassive black holes at the center of a galaxy
The material being pulled toward this disk-shaped black hole emits so much energy that J0529-4351 is more than 500 trillion times brighter than the Sun
The European Space Agency gets the green light for the first space observatory of its kind, dedicated to revealing space-time vibrations.
Intermediate-mass black holes (IMBHs) are a cosmic enigma, their very existence and mechanisms of formation shrouded in mystery
Research by an international team led by Shugo Nishiyama at Miyagi University shows that some of the stars closely circling the black hole at the center of the Milky Way galaxy may have come from a greater distance than previously thought, completely
Professor Zvi Piren, head of the Schwartzman Chair at the Rakah Institute of Physics at the Hebrew University and Professor Amir Levinson from Tel Aviv University will take part in a research group of the prestigious Simmons Foundation as part of an international collaboration
"The effect of gravitational waves on pulsars is very weak and difficult to detect, but we built the credibility of the findings over time as we collected more data," said Caterina Cazziano, NANOGrav team member and senior lecturer at Caltech.
A highly unusual burst of high-energy light from a nearby galaxy is linked by scientists to a neutron star merger
In a recent paper published in the journal Nature, scientists analyzed new data from the Event Horizon Telescope (EHT) to produce the most detailed image yet of the supermassive black hole at the center of the galaxy M87
A groundbreaking new map of dark matter has been created using data from the Dark Energy Survey (DES), in an international collaboration of astronomers and physicists. The map shows the distribution of dark matter in the southern sky region, and it is
An international team, which includes a group of researchers from Tel Aviv University, has identified the first black hole, Gaia BH1, which is 1500 light years from Earth
Gravitational wave analysis hints at the way black hole pairs are formed
A team of researchers from Australia recently made a new prediction about the strength of this gravitational wave signal. The new estimate is based on data from the MassiveBlack-II imager, which simulates a massive region of space that resembles a dissecting
Says Dr. Shahar Hadar, a theoretical astrophysicist from the University of Haifa and Oranim College who also works in the development of the next generation of the Event Horizon Telescope. He also explains why it took five years to produce the photograph
