    • Improved upper limit on degree-scale CMB B-mode polarization power from the 670 square-degree POLARBEAR survey 
      Adachi, S.; Adkins, T.; Aguilar Faúndez, Mario Andrés Osvaldo; Arnold, K. S.; Baccigalupi, C.; Barron, D.; Chapman, S.; Cheung, K.; Chinone, Y.; Crowley, K. T.; Elleflot, T.; Errard, J.; Fabbian, G.; Feng, C.; Fujino, T.; Galitzki, N.; Halverson, N. W.; Hasegawa, M.; Hazumi, M.; Hirose, H.; Howe, L.; Ito, J.; Jeong, O.; Kaneko, D.; Katayama, N.; Keating, B.; Kisner, T.; Krachmalnicoff, N.; Kusaka, A.; Lee, T.; Linder, E.; Lonappan, A. I.; Lowry, L. N.; Matsuda, F.; Matsumura, T.; Minami, Y.; Murata, M.; Nishino, H.; Nishinomiya, Y.; Poletti, D.; Reichardt, C. L.; Ross, C.; Segawa, Y.; Siritanasak, P.; Stompor, R.; Suzuki, A.; Tajima, O.; Takakura, S.; Takatori, S.; Tanabe, D.; Teply, G.; Yamada, K.; Zhou, Y. (IOP, 2022)
      We report an improved measurement of the degree-scale cosmic microwave background B-mode angular-power spectrum over 670 deg(2) sky area at 150 GHz with Polarbear. In the original analysis of the data, errors in the angle ...
    • The anisotropy of the microwave background to l = 3500: Mosaic observations with the cosmic background imager 
      Pearson, T. J.; Mason, B. S.; Readhead, A. C.S.; Shepherd, M. C.; Sievers, J. L.; Udomprasert, P. S.; Cartwright, J. K.; Farmer, A. J.; Padin, S.; Myers, S. T.; Bond, J. R.; Contaldi, C. R.; Pen, U. L.; Prunet, S.; Pogosyan, D.; Carlstrom, J. E.; Kovac, J.; Leitch, E. M.; Pryke. C.; Halverson, N. W.; Holzapfel, W. L.; Altamirano, P.; Bronfman Aguiló, Leonardo; Casassus Montero, Simón; May, J.; Joy, M. (Institute of Physics Publishing, 2003)
      Using the Cosmic Background Imager (CBI), a 13-element interferometer array operating in the 26-36 GHz frequency band, we have observed 40 deg 2 of sky in three pairs of fields, each ∼1457prime; × 165′, using overlapping ...
