polarization patterns in the sky to navigate.»
To test their prediction, the team led by Kataoka observed the young star HD 142527 with ALMA (note 1) and discovered, for the first time, the unique
polarization pattern in the dust disk around the star.
The waves left their own imprint on the CMB, scattering CMB photons in a way that created
the polarization pattern that Kovac and his colleagues observed.
Astrophysicists have predicted that this B - mode
polarization pattern is recorded ever so faintly in the cosmic microwave background.
Dust grains in the Galaxy could imprint a similar
polarization pattern in the CMB as gravitational waves can, but based on several different predictions of the galactic contribution the researchers concluded that their data was more likely to originate from primordial gravitational waves.
The polarization pattern that BICEP2 detected in the CMB could effectively be a snapshot of primordial gravitational waves.
PRYKE: About a year ago, we announced that we had detected this so called swirliness, this B - mode in the microwave background
polarization pattern.

This job
polarization seems to be related to global developments like technological change, trade
patterns, as well as institutional factors such as the decline of unionization.

patterns in the alignment, or
polarization, of the first light released into space just 380,000 years after the Big Bang, what's known as the cosmic microwave...
Because Virgo's detector isn't oriented parallel to the LIGO detectors, scientists could study the
polarization of the waves — the specific
pattern by which they stretch and squeeze spacetime — for the first time.
The gravitational waves produced a characteristic swirly
pattern in polarized light, called «B - mode»
polarization.
The result had hinged on the discovery of a curlicue
pattern in the
polarization of the cosmic microwave background, the Big Bang's relic radiation.

patterns in the
polarization of the CMB's microwaves, which Planck also mapped.
Gravitational waves from inflation generate a faint but distinctive twisting
pattern in the
polarization of the cosmic microwave background, known as a «curl» or B - mode
pattern.
«Our team hunted for a special type of
polarization called «B - modes,» which represents a twisting or «curl»
pattern in the polarized orientations of the ancient light,» said co-leader Jamie Bock (Caltech / JPL).
For the density fluctuations that generate most of the
polarization of the CMB, this part of the primordial
pattern is exactly zero.

polarization and temperature of the cosmic microwave background in a small patch of space, emitted when the universe was about 380,000 years old.

patterns in the alignment, or
polarization, of the first light released into space just 380,000 years after the Big Bang, what's known as the cosmic microwave background.
On Monday, March 17, 2014, BICEP - Keck collaboration, which operates an array of microwave telescopes located at the geographical South Pole, announced the discovery of
patterns in the
polarization of the cosmic microwave background that could have been generated in the early universe.
The theory is that these photons produced a curling
pattern of
polarization, called a B - mode, that is causally connected to what happens when an electron interacts with a gravitational wave.
This
pattern, basically a curling in the
polarization, or orientation, of the light, can be created only by gravitational waves produced by inflation.
Working with staff scientists Andreas Scholl and Elke Arenholz at the ALS, they used a 5 - volt probe from an atomic force microscope to switch the
polarization of the ferroelectric material up and down, creating a geometric
pattern of concentric squares.
Not only did the group succeed in visualizing the real time events of zygote
polarization and asymmetric cell division, they were able to quantify the dynamic
patterns of the cytoskeleton (i.e. formation of the ring structure and longitudinal array of MTs and F - actin, respectively).
That could be detected by looking for a particular
pattern of polarized light in the cosmic microwave background, known as B - mode
polarization.
These gravitational waves would have stamped a swirl
pattern, called «B - mode»
polarization, in the cosmic microwave background, the oldest light now detectable in the sky.
The consistency of
patterns highlights a key tension facing education advocates seeking to use federal policy to advance their goals: Any benefits from federal involvement may come at the cost of heightened partisan
polarization.
Kaino's short performance action results in a black, white and yellow tie - dyed
pattern upon the recognizable stars and stripes and serves as a larger allegory for the growing extreme
polarization of political thought in America today.
In observing that Lori was openly hostile toward and alienated from her mother, one expert also noted that Lori made statements glorifying her father, a
pattern of
polarization which could very well develop in Jaime if appellant is granted custody of both children.»
