How to observe a 'black hole symphony' using gravitational wave astronomy

Nov 19, 2019 (SPX)

In recent years, many researchers have made strides in understanding black holes using observational astronomy and an emerging field known as gravitational wave...

Weakened black hole allows its galaxy to awaken

Nov 19, 2019 (SPX)

Galaxy clusters are the largest structures in the cosmos that are held together by gravity, consisting of hundreds or thousands of galaxies embedded in hot gas,...

The measurements of the expansion of the universe don't add up

Nov 19, 2019 (SPX)

More than a hundred scientists met this summer at the Kavli Institute for Theoretical Physics at the University of California (USA) to try to clarify what is ha...

Hot electrons harvested without tricks

Nov 18, 2019 (SPX)

Materials scientists have been looking for ways to harvest this excess energy. Scientists from the University of Groningen and Nanyang Technological University ...

Study proposes light signature for detecting black hole mergers

Nov 15, 2019 (SPX)

"With a light signature, astronomers could easily pinpoint the cosmic location of these mergers and study them in much more detail than is presently possible," ...

Black hole mergers: Cooking with gas

Nov 14, 2019 (SPX)

"With a light signature, astronomers could easily pinpoint the cosmic location of these mergers and study them in much more detail than is presently possible," ...

Magnets for the second dimension

Nov 12, 2019 (SPX)

Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel ea...

Clemson scientists further refine how quickly the universe is expanding

Nov 11, 2019 (SPX)

In a paper published Friday, Nov. 8, in The Astrophysical Journal, Clemson scientists Marco Ajello, Abhishek Desai, Lea Marcotulli and Dieter Hartmann have coll...

Pac-Man-like mergers could explain massive, spinning black holes

Nov 11, 2019 (SPX)

In a new paper published in Physical Review Letters, the researchers suggest that such large mergers could happen just outside supermassive black holes at the c...

Light-based 'tractor beam' assembles materials at the nanoscale

Nov 05, 2019 (SPX)

Now imagine construction at a smaller scale - less than 1/100th the thickness of a piece of paper. This is the nanoscale. It is the scale at which scientists ar...

Scientists may have discovered whole new class of black holes

Nov 01, 2019 (SPX)

But new research shows that their search might have been missing an entire class of black holes that they didn't know existed. In a study published in the journ...

Ancient gas cloud shows that the first stars must have formed very quickly

Nov 01, 2019 (SPX)

When astronomers look at distant objects, they necessarily look back in time. The gas cloud discovered by Banados et al. is so distant that its light has taken ...

Evading Heisenberg isn't easy

Nov 01, 2019 (SPX)

But the sensitivity that we can achieve using purely conventional means is limited. For example, Heisenberg's uncertainty principle in quantum mechanics implies...

Researchers apply the squeeze to better detect stellar-mass black holes

Nov 01, 2019 (SPX)

Stellar-mass black holes are formed by the gravitational collapse of a star. Their collisions are some of the most violent events in the universe, creating grav...

UCF researchers discover mechanisms for the cause of the Big Bang

Nov 01, 2019 (SPX)

In a new paper appearing in Science Magazine, researchers detailed the mechanisms that could cause the explosion, which is key for the models that scientists us...

Putting the 'bang' in the Big Bang

Oct 28, 2019 (SPX)

Just before the Big Bang launched the universe onto its ever-expanding course, physicists believe, there was another, more explosive phase of the early universe...

JILA team demonstrates model system for distribution of more accurate time signals

Oct 25, 2019 (SPX)

The novel time scale architecture combines a super-reliable, advanced atomic clock with an ultrastable device for storing time signals and is a "blueprint for t...

How to spot a wormhole if they exist

Oct 24, 2019 (SPX)

Such pathways could connect one area of our universe to a different time and/or place within our universe, or to a different universe altogether. Whether wormho...
