Black holes

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
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 Shogo 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 further away than previously thought, completely outside the Milky Way.
Researchers have found that the star cluster IRS13 near the supermassive black hole SagittariusA* at the center of our galaxy is much younger than predicted
Professor Zvi Piren, the holder 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 cooperation in mathematics and physical sciences for the study of neutron stars and black holes
A Sun-like star located in a galaxy roughly 500 million light-years away is being gradually devoured by a black hole, shedding a mass equal to three Earths on each close pass.
"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.
NANOGrav Discovers Stronger Gravitational Waves Than Ever, Apparently Created by Pairs of Supermassive Black Holes
A significant development in thin layer technology could possibly improve the sensitivity of gravitational wave detectors.
An international group of astrophysicists discovered something completely new, hidden in the center of the Milky Way galaxy
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
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 Harvard University, MIT and Calcutta in collaboration with Google successfully simulated a traversable wormhole with the help of a quantum computer. The experiment performed on Google's quantum processor demonstrated the passage of information in the interlaced system. According to the principle of holography, the physics demonstrated in the experiment is the same as that of particles passing through wormholes. Although it was conducted on only nine qubits, the experiment is of great importance because it illustrates for the first time the possibility of testing quantum gravity with the help of entangled systems.
Cardiff University researchers have detected a strange twisting motion in the orbits of two colliding black holes, an exotic phenomenon predicted by Einstein's theory of gravity
The assessment: This is a collision of matter and antimatter in the vicinity of black holes or collapsed neutron stars known as magnetars
Unlike the supermassive black holes at the centers of galaxies, black holes with the masses of individual stars have no matter attracted to them or other nearby objects surrounding it, so they are difficult to detect
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 slice of our universe
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 photo published this week and what is planned to be done in order to improve the resolution
First image of the black hole at the center of our galaxy Sagittarius A* (Sagittarius Ai Kochav) which until now has been studied for its effect on other stars, this time we can see its event horizon. Photographed by the Ofek Al-Havain partnership which connected eight radio observatories into one radio telescope the size of the Earth
In 2020, a team led by astronomers from the European Southern Observatory (ESO) reported the closest black hole to Earth, which is only 1000 light years away. But other researchers have disputed their results. After further observations from the ground and from space, both the original researchers and their critics came to the conclusion that there is no black hole
Holes were able to detect a black hole that matter does not fall into or is not part of a binary system, thus it is not exposed to the eye and to almost any other instrument * Some telescopes that are under construction or ready to be used will be able to detect such individual black holes on a daily basis
Very light boson particles are a new type of subatomic particle that scientists have proposed as a compelling possibility for dark matter. But these very light particles, if they exist, are difficult to detect because their mass is very small and only rarely do they create interactions with other matter, this is one of the important properties of dark matter
The Hubble Space Telescope photographed a bright knot of gas hit by an invisible jet from the black hole, which is only 15 light years away. The black hole must have looked bright billions of years ago as a quasar, when our young galaxy was fed by lots of infalling gas. But after all this time the black hole is acting sporadically, unwilling to take a nap
