title = "Zeeman splitting in OH megamasers",
abstract = "We detected significant Zeeman splitting in the 1667 MHz OH megamaser emission from four ultraluminous galaxies. These detections, in addition to being the first extragalactic detection of the Zeeman effect in an emission line, suggest that OH megamasers are excellent extragalactic magnetometers.",

note = "Funding Information: This research was supported in part by NSF grant AST-0406987. Support for this work was also provided to TR through an IAU grant and by the NSF through award GSSP 06-0003 from the NRAO. TR would also like thank Vicki Drazenovic for her help. Funding Information: † The Arecibo Observatory is part of the National Astronomy and Ionosphere Center, which is operated by Cornell University under a cooperative agreement with the National Science Foundation. ‡ We use the classical definition of Stokes I, which is the sum (not the average) of two orthogonal polarizations. Thus, fluxes in Stokes I are twice the usual flux density given in catalogs.",
