Attosecond X-ray pulses at high repetition rates revolutionize atomic imaging
Nov 26, 2024 (SPX)
The researchers successfully created single-spike hard X-ray pulses with energies exceeding 100 microjoules and pulse durations of only a few hundred attosecond...
Unlocking the formation of early quasars with Super-Eddington growth
Nov 21, 2024 (SPX)
Quasars are luminous galactic nuclei powered by supermassive black holes that emit immense energy while drawing in surrounding matter. The quasars examined in t...
New research unveils the precise shape of a single photon
Nov 20, 2024 (SPX)
The study, featured in 'Physical Review Letters', delves deeply into the behavior of photons - elementary particles of light - and examines their emission by at...
Researcher explore dark matter's origins in potential dark Big Bang event
Nov 20, 2024 (SPX)
Assistant Professor Cosmin Ilie and senior Richard Casey examined the theory advanced by Katherine Freese and Martin Winkler from the University of Texas at Aus...
TBIRD technology could help image black holes' photon rings
Nov 20, 2024 (SPX)
The "camera" that took both images is the Event Horizon Telescope (EHT), which is not one singular instrument but rather a collection of radio telescopes situat...
How can electrons can split into fractions of themselves?
Nov 19, 2024 (SPX)
The new work is an effort to make sense of a discovery that was reported earlier this year by a different group of physicists at MIT, led by Assistant Professor...
We now know the origin of black hole magnetic fields their parent stars
Nov 19, 2024 (SPX)
Researchers from the Flatiron Institute, in collaboration with others, have now traced the source of black hole magnetism back to their progenitor stars. This d...
New pathway discovered for creating quantum spin liquid materials
Nov 16, 2024 (SPX)
Detailed in a study published in 'Nature Communications', the University of Birmingham research represents an essential step toward developing quantum materials...
Much ado about vacuum
Nov 16, 2024 (SPX)
Robert Todd leads one of these indispensable teams, the NSLS-II Vacuum Group. While the word "vacuum" may conjure up images of Hoovers and air-tight packages, t...
Swift studies gas-churning monster black holes
Nov 14, 2024 (SPX)
"It's a very weird event, called AT 2021hdr, that keeps recurring every few months," said Lorena Hernandez-Garcia, an astrophysicist at the Millennium Institute...
Einstein's predictions face new challenges with universe's expanding puzzle
Nov 12, 2024 (SPX)
Einstein's theory visualizes the Universe as a flexible sheet that distorts with the presence of matter, forming what are known as "gravitational wells." Light ...
Astrophysicists explore light echoes to study black holes
Nov 08, 2024 (SPX)
Published in 'The Astrophysical Journal Letters', the study outlines a method leveraging gravitational lensing, a process where light bends around black holes d...
Enhanced energy production through improved singlet fission efficiency
Nov 04, 2024 (SPX)
This is driven by the absorption of a photon by molecules known as chromophores, which absorb specific wavelengths of light. Controlling the orientation and arr...
eROSITA detects unique temperature and shape variations in the Local Hot Bubble
Oct 31, 2024 (SPX)
The Local Hot Bubble was initially proposed nearly 50 years ago to explain the soft X-ray background observed below 0.2 keV. Since X-ray photons at this energy ...
It's not to be. Universe too short for Shakespeare typing monkeys
Oct 31, 2024 (SPX)
