Sentences with phrase «in acoustic oscillations»

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.

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.

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.

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.

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.
