«Bats use polarized light to navigate: First mammal known to use
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.
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.
Not exact matches
The researchers had seen twirling
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...
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.
To give their study even more bite, they also look for accompanying
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).
The
patterns, so - called «B - mode
polarization,» are the signature of gravitational waves, or ripples
in space - time.
PRIMORDIAL SWIRL The
patterns and colors
in this visualization represent the
polarization and temperature of the cosmic microwave background
in a small patch of space, emitted when the universe was about 380,000 years old.
The researchers had seen twirling
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.
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.
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.
This
pattern, basically a curling
in the
polarization, or orientation, of the light, can be created only by gravitational waves produced by inflation.
The
polarization pattern that BICEP2 detected
in the CMB could effectively be a snapshot of primordial gravitational waves.
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.
PRYKE: About a year ago, we announced that we had detected this so called swirliness, this B - mode
in the microwave background
polarization pattern.
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.
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.&raqu
