Mon, 25 Sep 2023 12:48:31 EDT //www.koonmotors.com/releases/2023/09/230925124831.htm //www.koonmotors.com/releases/2023/09/230920110420.htm While previous researchers have hypothesized that black holes eat slowly, new simulations indicate that black holes scarf food much faster than conventional understanding suggests. Some quasars brighten and disappear within months -- a time scale that aligns with the new findings. Wed, 20 Sep 2023 11:04:20 EDT //www.koonmotors.com/releases/2023/09/230920110420.htm //www.koonmotors.com/releases/2023/09/230912110158.htm At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are activated by the presence of massive dark matter halos (DMH) surrounding the galaxy, directing matter towards the center, feeding the black hole. A team has now surveyed hundreds of ancient quasars and found this behavior is very consistent throughout history. This is surprising, as many large-scale processes show variation throughout the life of the universe, so the mechanism of quasar activation could have implications for the evolution of the entire universe.

Fri, 08 Sep 2023 13:00:01 EDT //www.koonmotors.com/releases/2023/09/230908130001.htm //www.koonmotors.com/releases/2023/09/230907130334.htm Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.

Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.

The team revealed features of a microquasar system that have never before been seen. Using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers discovered a quasi-periodic oscillation (QPO) signal in the radio band for the first time from any microquasar systems.

The galaxy, CEERS 1019, existed about 570 million years after the big bang, and its black hole is less massive than any other yet identified in the early universe.

But just how quickly celestial objects are receding from each other is still up for debate. Sat, 01 Jul 2023 13:56:24 EDT //www.koonmotors.com/releases/2023/07/230701135624.htm //www.koonmotors.com/releases/2023/06/230629173611.htm Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This 'cosmic web' started out tenuous and became more distinct over time as gravity drew matter together. Thu, 29 Jun 2023 17:36:11 EDT //www.koonmotors.com/releases/2023/06/230629173611.htm //www.koonmotors.com/releases/2023/06/230629125715.htm 黑洞,一些最迷人的实体in the cosmos, possess an immense gravitational pull so strong that not even light can escape. The groundbreaking detection of gravitational waves in 2015, caused by the coalescence of two black holes, opened a new window into the universe. Since then, dozens of such observations have sparked the quest among astrophysicists to understand their astrophysical origins. Thanks to the POSYDON code's recent major advancements in simulating binary-star populations, a team of scientists predicted the existence of merging massive, 30 solar mass black hole binaries in Milky Way-like galaxies, challenging previous theories. Thu, 29 Jun 2023 12:57:15 EDT //www.koonmotors.com/releases/2023/06/230629125715.htm //www.koonmotors.com/releases/2023/06/230629125650.htm You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy. New results are the first evidence of the gravitational wave background -- a sort of soup of spacetime distortions pervading the entire universe and long predicted to exist by scientists. Thu, 29 Jun 2023 12:56:50 EDT //www.koonmotors.com/releases/2023/06/230629125650.htm //www.koonmotors.com/releases/2023/06/230628125125.htm For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big Bang. Wed, 28 Jun 2023 12:51:25 EDT //www.koonmotors.com/releases/2023/06/230628125125.htm //www.koonmotors.com/releases/2023/06/230622120817.htm Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy. Thu, 22 Jun 2023 12:08:17 EDT //www.koonmotors.com/releases/2023/06/230622120817.htm //www.koonmotors.com/releases/2023/06/230621121018.htm 一个国际科学家小组发现了that Sagittarius A* (Sgr A*), the supermassive black hole at the centre of the Milky Way, emerged from a long period of dormancy some 200 years ago. The team, led by Frédéric Marin, a CNRS researcher at the Astronomical Strasbourg Observatory (CNRS/University of Strasbourg), has revealed the past awakening of this gigantic object, which is four million times more massive than the Sun. Their work is published in Nature on 21 June. Wed, 21 Jun 2023 12:10:18 EDT //www.koonmotors.com/releases/2023/06/230621121018.htm //www.koonmotors.com/releases/2023/06/230607215802.htm Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so dazzling.

Now researchers suggest looking at a new, unexpected and entirely unexplored place: The turbulent, energetic cocoons of debris that surround dying massive stars. Mon, 05 Jun 2023 18:12:02 EDT //www.koonmotors.com/releases/2023/06/230605181202.htm //www.koonmotors.com/releases/2023/06/230603220820.htm Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational lensing quasars is expected to multiply with the launch of Euclid this summer. Sat, 03 Jun 2023 22:08:20 EDT //www.koonmotors.com/releases/2023/06/230603220820.htm //www.koonmotors.com/releases/2023/06/230602115051.htm New theoretical research has shown that Stephen Hawking was likely right about black holes, although not completely. Due to Hawking radiation, black holes will eventually evaporate, but the event horizon is not as crucial as had been believed. Gravity and the curvature of spacetime cause this radiation too. This means that all large objects in the universe, like the remnants of stars, will eventually evaporate.

Now, astronomers have discovered a new population of filaments -- but these threads are much shorter and lie horizontally or radially, spreading out like spokes on a wheel from the black hole. Fri, 02 Jun 2023 11:50:40 EDT //www.koonmotors.com/releases/2023/06/230602115040.htm //www.koonmotors.com/releases/2023/05/230529171520.htm Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years.

Supermassive stars typically are formed in pairs, but the new study found that all 16 of the stars were singletons. The findings support a scenario in which the supermassive black hole drives nearby stars to either merge or be disrupted, with one of the pair being ejected from the system.

The researchers found that the stars, located in a neighboring dwarf galaxy called the Small Magellanic Cloud, are in partial contact and swapping material with each other, with one star currently 'feeding' off the other. They orbit each other every three days and are the most massive touching stars (known as contact binaries) yet observed.

Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.

This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long 'contrail' of newborn stars, twice the diameter of our Milky Way galaxy. It's likely the result of a rare, bizarre game of galactic billiards among three massive black holes.

Using NASA's Hubble Space Telescope and other space and ground-based observatories, astronomers investigating these developments have made an unexpected and rare discovery: a pair of gravitationally bound quasars, both blazing away inside two merging galaxies. They existed when the universe was just 3 billion years old.

Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.

A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.

As the star is shredded, its remnants are transformed into a stream of debris that rains back down onto the black hole to form a very hot, very bright disk of material swirling around the black hole, called an accretion disc. This phenomenon -- where a star is destroyed by a supermassive black hole and fuels a luminous accretion flare -- is known as a tidal disruption event (TDE), and it is predicted that TDEs occur roughly once every 10,000 to 100,000 years in a given galaxy.

What's more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe.

This fleeting, massive object likely formed from the collision of two neutron stars.

More data will be needed to determine whether the invisible giants arose from a quiet galactic disk or a more dynamic cluster of stars.

The results suggest that the narrowing of the jet is independent of the activity level of the galaxy which launched it.
