  • COSMOGLOBE DR1 results. I. Improved Wilkinson Microwave Anisotropy Probe maps through Bayesian end-to-end analysis 
    Watts, D. J; Basyrov, A; Eskilt, J. R; Galloway, M; Gjerlow, E; Hergt, L. T; Herman, D; Ihle, H. T; Paradiso, S; Fazlu, Rahman; Thommesen, H; Aurlien, R; Bersanelli, M; Bianchi, L. A; Brilenkov, M; Colombo, L. P. L; Eriksen, H. K; Franceschet, C; Fuskeland, U; Hensley, B; Hoerning, G. A; Lee, K; Lunde, J. G. S; Marins, A; Nerval, S. K; Patel, S. K; Regnier, M; San, M; Sanyal, S; Stutzer, N.O; Verma, A; Wehus, I. K; Zhou, Y (EDP Sciences, 2023-11)
    We present COSMOGLOBE Data Release 1, which implements the first joint analysis of WMAP and Planck LFI time-ordered data, processed within a single Bayesian end-to-end framework. This framework directly builds on a similar ...
  • COSMOGLOBE DR1 results. II. Constraints on isotropic cosmic birefringence from reprocessed WMAP and Planck LFI data 
    Eskilt, J. R; Watts, D. J; Aurlien, R; Basyrov, A; Bersanelli, M; Brilenkov, M; Colombo, L. P. L; Eriksen, H. K; Fornazier, K. S. F; Franceschet, C; Fuskeland, U; Galloway, M; Gjerlow, E; Hensley, B; Hergt, L. T; Herman, D; Ihle, H. T; Lee, K; Lunde, J. G. S; Nerval, S. K; Paradiso, S; Patel, S. K; Fazlu, Rahman; Regnier, M; San, M; Sanyal, S; Stutzer, N. O.; Thommesen, H; Verma, A; Wehus, I. K; Zhou, Y (EDP Sciences, 2023-11)
    Cosmic birefringence is a parity-violating effect that might have rotated the plane of the linearly polarized light of the cosmic microwave background (CMB) by an angle β since its emission. This angle has recently been ...
  • Cosmoglobe: Towards end-to-end CMB cosmological parameter estimation without likelihood approximations 
    Eskilt, J. R; Lee, K; Watts, D. J; Anshu, V; Aurlien, R; Basyrov, A; Bersanelli, M; Colombo, L. P. L; Eriksen, H. K; Fornazier, K. S. F; Fuskeland, U; Galloway, M; Gjerlow, E; Hergt, L. T; Ihle, H. T; Lunde, J. G. S; Marins, A; Nerval, S. K; Paradiso, S; Rahman, Fazlu; San, M; Stutzer, N. O; Wehus, I. K (EDP Sciences, 2023-10)
    We implement support for a cosmological parameter estimation algorithm in Commander and quantify its computational efficiency and cost. For a semi-realistic simulation similar to Planck LFI 70 GHz, we find that the ...
