A mathematical tool to help understand fractal structure of quark-gluon plasma
Jun 07, 2022 (SPX)
One of the discoveries, evidence for which is steadily accumulating, is that quark-gluon plasma has a fractal structure. When it disintegrates into a stream of ...
Cosmological gravitational waves: A new approach to reach back to the Big Bang
Jun 07, 2022 (SPX)
A new study by the POLARBEAR collaboration, led by SISSA for the part concerning the interpretation for Cosmology and published in the Astrophysical Journal, pr...
Researchers create simulations studying the lifecycle of ancestor galaxy cities
Jun 07, 2022 (SPX)
Cosmological simulations are crucial to studying how the universe became the shape it is today, but many do not typically match what astronomers observe through...
Putting the theory of special relativity into practice, by counting galaxies
Jun 06, 2022 (SPX)
Now, new research from CU Boulder adds yet another piece of evidence to the case for mediocrity: Galaxies are, on average, at rest with respect to the early uni...
Time crystals impossible but obey quantum physics
Jun 03, 2022 (SPX)
It comes after the same team recently witnessed the first interaction of the new phase of matter. Time crystals were long believed to be impossible because they...
Algorithm simulates intergalactic medium of the Universe in seconds
Jun 03, 2022 (SPX)
The research has also made it possible to reproduce with high precision the so-called "Lyman-alpha forests", a pattern of lines in the spectra of distant galaxi...
A new duality solves a physics mystery
Jun 02, 2022 (SPX)
"Our work may revolutionize the general public's understanding of curvatures and distance," says Qi Zhou, Professor of Physics and Astronomy. "It has also answe...
Black holes helped quenching star formation in the early Universe
Jun 02, 2022 (SPX)
Hundreds of galaxies are seen in this region of the sky, called COSMOS. The most distant ones are seen as small, red specks, enlarged along the edge of the imag...
Uncorking champagne bottle produces supersonic shock waves
Jun 02, 2022 (SPX)
But there is much more that comes out of the pop than meets the senses, according to researchers in France and India. In Physics of Fluids, by AIP Publishing, c...
Finding coherence in quantum chaos
May 27, 2022 (SPX)
"By applying balanced energy gain and loss to an open quantum system, we found a way to overcome a previously held limitation that assumed interactions with the...
How the universe got its magnetic field
May 26, 2022 (SPX)
In previous research, scientists came to understand how turbulence, the churning motion common to fluids of all types, could amplify preexisting magnetic fields...
Astronomers find hidden trove of massive black holes
May 25, 2022 (SPX)
As a giant spiral galaxy, the Milky Way is believed to have been built up from mergers of many smaller dwarf galaxies. For example, the Magellanic Clouds seen i...
Halting a wave in its tracks
May 24, 2022 (SPX)
In particular, nonreciprocal platforms, may support unidirectional channels that allow propagation in a given direction of space-let's say from left to right, b...
Unraveling a perplexing explosive process that occurs throughout the universe
May 24, 2022 (SPX)
Producing the extraordinary bursts in space are celestial bodies such as neutron, or collapsed, stars called magnetars (magnet + star) enclosed in extreme magne...
Custom 'headphones' boost atomic radio reception 100-fold
May 24, 2022 (SPX)
The structure - a square overhead loop connecting two square panels - increases the incoming radio signal, or electric field, applied to the gaseous atoms in th...
Hubble Reaches New Milestone in Mystery of Universe's Expansion Rate
May 20, 2022 (SPX)
Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges Lemaitre. In 1998, this led to the disc...
DARPA pursues tactical-grade clock that maintains precision over time
May 18, 2022 (SPX)
To overcome these limitations, DARPA's H6 program seeks to develop ultra-small, low-power, fieldable clocks that can maintain their microsecond timing precision...
Black hole scientist: 'Wherever we look, we should see donuts'
May 16, 2022 (SPX)
In 2019, the image of M87*, a supermassive black hole in a galaxy more than 50 million light-years from Earth, graced the cover pages of virtually every news ou...
Making sense of the nonsensical: Black holes and the simulation library
May 16, 2022 (SPX)
The first image, of the black hole at the center of the Messier 87 galaxy, was released in 2019. The latest image, released Thursday, shows the black hole at th...
New NASA Black Hole Sonifications with a Remix
May 13, 2022 (SPX)
In some ways, this sonification is unlike any other done before (1, 2, 3, 4) because it revisits the actual sound waves discovered in data from NASA's Chandra X...
