The word "multipoles" in example sentences

These include the “axis of evil” alignment of low multipoles, the existence of an anomalous cold spot in the CMB, an anomalous dipole power asymmetry, a claimed “dark flow” of galaxy clusters measured by the Sunyaev-Zeldovich effect, as well as a possible detection of a quadrupole power asymmetry of the type predicted by ACW in the WMAP five-year data. ❋ Sean (2008)

They barely have enough signal-to-noise to constrain a very few full-sky multipoles at the very largest scales, and not much more than that. ❋ Sean (2008)

To use the LAGEOS satellites to measure frame dragging, the full gravitational field of the Earth needs to be accounted for (in particular, the mass multipoles due to the non-sphericitiy of the Earth). ❋ Daniel (2007)

We confirm that although there is no apparent lack of power at large angular scales for the full-sky maps, the lowest multipoles of the WMAP data happen to have the magnitudes and orientations, with respect to the Galactic plane, that are needed to make the large scale power in cut-sky maps surprisingly small. ❋ Sean (2007)

If the current full-sky map is correct, there is no clear deficit of power at large angular scales and the alignment of the l = 2 and l = 3 multipoles remains the primary intriguing feature in the full-sky maps. ❋ Sean (2007)

The multipoles 'alignment, however, is indeed anomalous, and extends up to $\ell = 5$ rejecting statistical isotropy with a probability in excess of 99.9%. ❋ Unknown (2005)

If the microwave background at the multipoles is correlated with the geometry and direction of motion of the solar system, and the incoherence manifests via octopole and quadrupole components in a bound universe, then there should be a center of gravity at the center of the visible universe that correlates to the ecliptic. ❋ Sean (2006)

Lawrence Krauss pointed out that the amplitude of the quadrupole moment of the CMBR is unexpectedly low, and the other low multipoles are observed to be preferentially aligned with the ecliptic plane. ❋ Sean (2006)

What is perhaps not so widely discussed is that two of the lowest multipoles - the quadrupole and octopole - are tightly correlated in the sense that the quadrupole plane and the three octopole planes are aligned. ❋ Mark (2005)

Paul, which led to the Paul trap, are based on investigations of the properties of electric and magnetic so called multipoles. ❋ Unknown (1989)

Plasmons decay (into incoherent electron-hole pair excitations), eventually dissipating their energy as the sloshing electrons scatter instead of oscillating smoothly, and as oscillating electric dipoles (and other multipoles) radiate. ❋ Unknown (2009)

These include the "axis of evil" alignment of low multipoles, the existence of an anomalous cold spot in the CMB, an anomalous dipole power asymmetry, a claimed "dark flow" of galaxy clusters measured by the Sunyaev-Zeldovich effect, as well as a possible detection of a quadrupole power asymmetry of the type predicted by ACW in the WMAP five-year data. ❋ Unknown (2008)
