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 ...

A.O.; Akiba, Y.; Arnold, K.; Baccigalupi, C.; Barron, D.; Beck, D.; Bianchini, F.; Boettger, D.; Borrill, J.; Cheung, K.; Chinone, Y.; Elleflot, T.; Errard, J.; Fabbian, G.; Feng, C.; Goeckner-Wald, N.; Hamada, T.; Hasegawa, M.; Hazumi, M.; Howe, L.; Kaneko, D.; Katayama, N.; Keating, B.; Keskitalo, R.; Kisner, T.; Krachmalnicoff, N.; Kusaka, A.; Lee, A. T.; Lowry, L. N.; Matsuda, F. T.; May, A. J.; Minami, Y.; Navaroli, M.; Nishino, H.; Piccirillo, L.; Poletti, D.; Puglisi, G.; Reichardt, C. L.; Segawa, Y.; Silva Feaver, M.; Siritanasak, P.; Suzuki, A.; Tajima, O.; Takatori, S.; Tanabe, D.; Teply, G. P.; Tsai, C. (Institute of Physics, 2019)
      The polarization of the atmosphere has been a long-standing concern for ground-based experiments targeting cosmic microwave background (CMB) polarization. Ice crystals in upper tropospheric clouds scatter thermal radiation ...
