J/MNRAS/401/1388    Radio polarization of WMAP point sources (Jackson+, 2010)

High-frequency radio polarization measurements of WMAP point sources. Jackson N., Browne I.W.A., Battye R.A., Gabuzda D., Taylor A.C. <Mon. Not. R. Astron. Soc., 401, 1388-1398 (2010)> =2010MNRAS.401.1388J
ADC_Keywords: Radio sources ; Polarization Keywords: polarization - galaxies: active - radio continuum: galaxies Abstract: We present polarization measurements at 8.4GHz (X-band), 22GHz (K-band), and 43GHz (Q-band) made with the Very Large Array (VLA) of a complete sample of extragalactic sources stronger than 1Jy in the 5yr Wilkinson Microwave Anisotropy Probe (WMAP, Cat. J/ApJS/180/283) catalogue and with declinations north of −34°. The observations were motivated by the need to know the polarization properties of radio sources at frequencies of tens of GHz in order to subtract polarized foregrounds for future sensitive cosmic microwave background (CMB) experiments. The total intensity and polarization measurements are generally consistent with comparable VLA calibration measurements for less-variable sources, and within a similar range to WMAP fluxes for unresolved sources. A further paper will present correlations between measured parameters and derive implications for CMB measurements. Description: Observations were conducted using the VLA in D-configuration between 01.40 and 19.30 UT on 2008 August 1. File Summary:

Note (1): i indicates fluxes from CLASS, in the case of multiple observations using the one with the lowest error in polarized flux density. Note (2): A '0.0' error means smaller than 1mJy. Note (3): * indicates that the measurement has been taken from the Q and U maps, rather than the fits to the u-v data (see text for details).
