    • A centimetre-wave excess over free–free emission in planetary nebulae 
      Casassus Montero, Simón; Nyman, L. A.; Dickinson, C.; Pearson, T. J. (WILEY-BLACKWELL, 2007-12-21)
      We report a centimetre-wave (cm-wave, 5-31 GHz) excess over free-free emission in planetary nebulae (PNe). Accurate 31- and 250-GHz measurements show that the 31-GHz flux densities in our sample are systematically higher ...
    • Anomalous radio emission from dust in the Helix 
      Casassus Montero, Simón; Readhead, A. C. S.; Pearson, T. J.; Nyman, L. A.; Shepherd, M. C.; Bronfman Aguiló, Leonardo (UNIV CHICAGO PRESS, 2004-03-10)
      A by-product of experiments designed to map the cosmic microwave background is the recent detection of a new component of foreground Galactic emission. The anomalous foreground at similar to 10 - 30 GHz, unexplained by ...
    • Dust-correlated cm wavelength continuum emission from translucent clouds ζ Oph and LDN 1780 
      Vidal, M.; Casassus Montero, Simón; Dickinson, C.; Witt, A. N.; Castellanos, P.; Davies, R. D.; Davis, R. J.; Cabrera, G.; Cleary, K.; Allison, J. R.; Bond, J. R.; Bronfman Aguiló, Leonardo; Bustos, R.; Jones, M. E.; Paladini, R.; Pearson, T. J.; Readhead, A. C. S.; Reeves, R.; Sievers, J. L.; Taylor, A. C. (2011)
      The diffuse cm wave IR-correlated signal, the ‘anomalous’ CMB foreground, is thought to arise in the dust in cirrus clouds.We present Cosmic Background Imager (CBI) cm wave data of two translucent clouds, ζ Oph and LDN ...
    • Extended mosaic observations with the Cosmic Background Imager 
      Readhead, A. C. S.; Mason, B. S.; Contaldi, C. R.; Pearson, T. J.; Bond, J. R.; Myers, S. T.; Padin, S.; Sievers, J. L.; Cartwright, J. K.; Shepherd, M. C.; Pogosyan, D.; Prunet, S.; Altamirano, P.; Bustos, R.; Bronfman Aguiló, Leonardo; Casassus Montero, Simón; Holzapfel, W. L.; May Humeres, Jorge; Pen, U.-L.; Torres, S.; Udomprasert, P. S. (IOP PUBLISHING, 2004-07-10)
      Two years of microwave background observations with the Cosmic Background Imager ( CBI) have been combined to give a sensitive, high-resolution angular power spectrum over the range 400 < l < 3500. This power spectrum has ...
    • Implications of the cosmic background imager polarization data 
      Sievers, J. L.; Achermann, C.; Bond, J. R.; Bronfman Aguiló, Leonardo; Bustos, R.; Contaldi, C. R.; Dickinson, C.; Ferreira, P. G.; Jones, M. E.; Lewis, A. M.; Mason, B. S.; May Humeres, Jorge; Myers, S. T.; Oyarce, N.; Padin, S.; Pearson, T. J.; Pospieszalski, M.; Readhead, A. C. S.; Reeves, R.; Taylor, A. C.; Torres, S. (2007)
      We present new measurements of the power spectra of the E mode of cosmic microwave background (CMB) polarization, the temperature T, the cross-correlation of E and T, and upper limits on the B mode from 2.5 yr of dedicated ...
    • Infrared-correlated 31-GHz radio emission from Orion East 
      Dickinson, C.; Casassus Montero, Simón; Davies, R. D.; Allison, J.; Bustos, R.; Cleary, K.; Davis, R. J.; Jones, M. E.; Pearson, T. J.; Readhead, A. C. S.; Reeves, R.; Taylor, A. C.; Tibbs, C. T.; Watson, R. A. (WILEY-BLACKWELL PUBLISHING, 2010-10-01)
      Lynds dark cloud LDN1622 represents one of the best examples of anomalous dust emission, possibly originating from small spinning dust grains. We present Cosmic Background Imager (CBI) 31-GHz data of LDN1621, a diffuse ...
    • The Q/U Imaging ExperimenT: Polarization Measurements of the Galactic Plane at 43 and 95 GHz 
      Ruud, T. M.; Fuskeland, U.; Wehus, I. K.; Vidal, M.; Araujo, D.; Bischoff, C.; Buder, I.; Chinone, Y.; Cleary, K.; Dumoulin, R. N.; Kusaka, A.; Monsalve, R.; Næss, S. K.; Newburgh, L. B.; Reeves, R. A.; Zwart, J. T. L.; Bronfman Aguiló, Leonardo; Davies, R. D.; Davis, R.; Dickinson, C.; Eriksen, H. K.; Gaier, T.; Gundersen, J. O.; Hasegawa, M.; Hazumi, M.; Huffenberger, K. M.; Jones, M. E.; Lawrence, C. R.; Leitch, E. M.; Limon, M.; Miller, A. D.; Pearson, T. J.; Piccirillo, L.; Radford, S. J. E.; Readhead, A. C. S.; Samtleben, D.; Seiffert, M.; Shepherd, M. C.; Staggs, S. T.; Tajima, O.; Thompson, K. L. (IOP Publishing, 2015)
      We present polarization observations of two Galactic plane fields centered on Galactic coordinates (l, b) = (0 degrees, 0 degrees) and (329 degrees, 0 degrees) at both Q (43 GHz) and W bands (95 GHz), covering between 301 ...
    • Vela X at 31 GHz 
      Hales, A. S.; Casassus Montero, Simón; Álvarez Moreno, Héctor Julio; May Humeres, Jorge; Bronfman Aguiló, Leonardo; Readhead, A. C. S.; Pearson, T. J.; Mason, B. S.; Dodson, R. (IOP PUBLISHING LTD, 2004-10-01)
      We present observations of the Vela X region at 31 GHz using the Cosmic Background Imager ( CBI). We find a strong compact radio source (5.'9 x 4.'1, FWHM) about the Vela pulsar, which we associate with the Vela pulsar ...
