BeyondPlanck II. CMB map-making through Gibbs sampling
E. Keihänen, A. -S. Suur-Uski, K. J. Andersen +37
We present a Gibbs sampling solution to the map-making problem for CMB measurements, building on existing destriping methodology. Gibbs sampling breaks the computationally heavy de…
BeyondPlanck XV. Polarized foreground emission between 30 and 70 GHz
T. L. Svalheim, K. J. Andersen, R. Aurlien +35
We constrain polarized foreground emission between 30 and 70 GHz with the Planck Low Frequency Instrument (LFI) and WMAP data within the global Bayesian BeyondPlanck framework. We…
BeyondPlanck VII. Bayesian estimation of gain and absolute calibration for CMB experiments
E. Gjerløw, H. T. Ihle, S. Galeotta +35
We present a Bayesian calibration algorithm for CMB observations as implemented within the global end-to-end BeyondPlanck (BP) framework, and apply this to the Planck Low Frequency…
BeyondPlanck VI. Noise characterization and modelling
H. T. Ihle, M. Bersanelli, C. Franceschet +38
We present a Bayesian method for estimating instrumental noise parameters and propagating noise uncertainties within the global BeyondPlanck Gibbs sampling framework, and apply thi…
BeyondPlanck I. Global Bayesian analysis of the Planck Low Frequency Instrument data
BeyondPlanck Collaboration, K. J. Andersen, R. Aurlien +42
We describe the BeyondPlanck project in terms of motivation, methodology and main products, and provide a guide to a set of companion papers that describe each result in fuller det…
Performance and energy footprint assessment of FPGAs and GPUs on HPC systems using Astrophysics application
David Goz, Georgios Ieronymakis, Vassilis Papaefstathiou +7
New challenges in Astronomy and Astrophysics (AA) are urging the need for a large number of exceptionally computationally intensive simulations. "Exascale" (and beyond) computation…
