No Relation Between a Supermassive Black Hole and Its Host Galaxy
Feb 21, 2018 (SPX)
According to a popular scenario explaining the formation and evolution of galaxies and supermassive black holes, radiation from galactic centers - where superma...
New hole-punched crystal clears a path for quantum light
Feb 20, 2018 (SPX)
The device, described in the journal Science, features a way for the quantum light to seamlessly move, unaffected by certain obstacles. "This design incorporate...
Rotating dusty gaseous donut around an active supermassive black hole
Feb 15, 2018 (SPX)
Aiming to solve this shadowy problem, a team of astronomers utilized the high resolution of ALMA to observe the center of spiral galaxy M77. The central region ...
Captured electrons excite nuclei to higher energy states
Feb 15, 2018 (SPX)
Physicists first predicted the effect, called nuclear excitation by electron capture (NEEC), over 40 years ago. But scientists had not seen it until now. Using ...
Scientists make first direct observation of electron frolic
Feb 15, 2018 (SPX)
The spectacle of these subatomic showers is legendary. Green, red, and purple waltz across the night sky, blending into one another for a fantastic show widely ...
Supermassive black hole model predicts characteristic light signals at cusp of collision
Feb 15, 2018 (SPX)
The RIT-led study represents the first step toward predicting the approaching merger of supermassive black holes using the two channels of information now avail...
Supermassive black holes can feast on one star per year
Feb 12, 2018 (SPX)
The research, which was recently published in The Astrophysical Journal, also suggests an answer to a longstanding astronomical mystery about the behavior of ec...
Large Hadron Collider experiment shows potential evidence of quasiparticle sought for decades
Feb 09, 2018 (SPX)
Now, a team of high-energy experimental particle physicists, including several from the University of Kansas, has uncovered possible evidence of a subatomic qua...
New technique can capture images of ultrafast energy-time entangled photon pairs
Feb 08, 2018 (SPX)
"This technique will allow us to explore all sorts of quantum effects that were inaccessible because the detectors were simply too slow," said Jean-Philippe Mac...
NASA Tests Atomic Clock for Deep Space Navigation
Feb 08, 2018 (SPX)
Currently, most missions rely on ground-based antennas paired with atomic clocks for navigation. Ground antennas send narrowly focused signals to spacecraft, wh...
Black holes regulate star formation in massive galaxies
Feb 07, 2018 (SPX)
In addition during this period (the "active phase" of the galaxy, referred to as an AGN or Active Galactic Nucleus) matter is expelled from outside the black ho...
Mind your speed: A magnetic brake on proton acceleration
Feb 05, 2018 (SPX)
The problem occurs when trying to push the proton energies beyond about 100 mega-electronvolts. Up to that point, the energies scale nicely with the laser inten...
Scientists get better numbers on what happens when electrons get wet
Feb 05, 2018 (SPX)
An article published in Nature Communications on Jan. 16 offers a new and better set of numbers from researchers at the University of Chicago, Argonne and Lawre...
Unexpected matter found in hostile black hole winds
Feb 01, 2018 (SPX)
Astronomers questioned how anything could survive the heat of the energetic outflows, but a new theory from researchers in Northwestern University's Center for ...
Relativity matters: Two opposing views of the magnetic force reconciled
Jan 30, 2018 (SPX)
For elementary particles, such as muons or neutrinos, the magnetic force applied to such charges is unique and immutable. However, unlike the electric charge, t...
Scientists find two ways to create 4D quantum Hall effect
Jan 29, 2018 (UPI)
"We don't have four spatial dimensions," researcher Mikael Rechtsman, a physicist at Penn State University, told UPI. Physicists have been interested in the qua...
First evidence of winds outside black holes throughout their mealtimes
Jan 26, 2018 (SPX)
The study, published in Nature, sheds new light on how mass transfers to black holes and how black holes can affect the environment around them. The research wa...
A new architecture for miniaturization of atomic clocks
Jan 25, 2018 (SPX)
We propose a new microwave generator that exploits thickness extensional (TE) vibration in a piezoelectric thin film to miniaturize an atomic clock. The TE mode...
A look into the fourth dimension
Jan 23, 2018 (SPX)
In the arts Salvador Dali tried that: his crucifixion scene painted in 1954 shows as cross consisting of the three-dimensional unfolding of a hypercube in four ...
Black hole jets account for three highest-energy particles in the universe
Jan 22, 2018 (UPI)
Astronomers at Penn State University found all three particle types supply the universe with similar levels off power input, despite each particle type carrying...
