Sentences with phrase «acoustic oscillations»

"Acoustic oscillations" refers to the wavelike motion of sound waves in a particular space or medium, such as air or water. It describes the back-and-forth movement of particles caused by the vibrations of these waves, which creates audible sound. So, the phrase means the rhythmic vibrations or movements of air molecules that generate sound waves. Full definition
The tug - of - war drove a series of acoustic oscillations within the fluid.
They employed a broad spectrum of methods and other measurement data, including Baryonic Acoustic Oscillations, which are density waves from the early universe, local measurements of the Hubble constant, which specifies the universe's rate of expansion at the present day, as well as a certain group of supernovae or exploding stars.
Hill's NSO colleague Sushanta Tripathy also turned to helioseismology to investigate the recent solar minimum, finding that in acoustic oscillations deep within the sun there were in fact two separate minima — one in late 2007 that did not correspond to the sunspot minimum, and one around late 2008 that did.
With helioseismology data, which track acoustic oscillations on the sun, researchers can follow the development of the jet stream thousands of kilometers below the sun's surface, potentially allowing for better forecasts of the timing of the solar cycle.
With helioseismology data, which track acoustic oscillations on the sun, researchers can check in on the progress of the jet stream at depths of roughly 1,000 kilometers, potentially allowing for better forecasts of the timing of the solar cycle.
«Two years ago, with 48,000 quasars, we first detected baryon acoustic oscillations in these maps.
Astronomers are probing the process by watching acoustic oscillations that resonate through the sun's outer layers (see «Here Comes the Sun,» Discover, May 2004).
BOSS measures the expansion rate of the Universe by determining the size of the baryonic acoustic oscillations (BAO) in the three - dimensional distribution of galaxies.
BOSS employs both galaxies and distant quasars to measure baryon acoustic oscillations (BAO), a signature imprint in the way matter is distributed, resulting from conditions in the early universe.
A third scientist used helioseismology to look at minima in acoustic oscillations that often correspond with sunspot minima.
And our understanding of ring structure now includes the gratifying confirmation of a prediction Mark Marley, now at NASA's Ames Research Center, and I made in 1993: that acoustic oscillations within the body of Saturn could also create features in the rings.
The study used data from the Baryon Oscillation Spectroscopic Survey, or BOSS, an Earth - based sky survey that captured light from about 1.5 million galaxies to study the universe's expansion and the patterned distribution of matter in the universe set in motion by the propagation of sound waves, or «baryonic acoustic oscillations,» rippling in the early universe.
