Coupling Oceanic Observation Systems to Study Mesoscale Ocean Dynamics
Gautier Cosne, Guillaume Maze, Pierre Tandeo
Understanding local currents in the North Atlantic region of the ocean is a key part of modelling heat transfer and global climate patterns. Satellites provide a surface signature…
Reionization optical depth determination from Planck HFI data with ten percent accuracy
L. Pagano, J. -M. Delouis, S. Mottet +2
We present an estimation of the reionization optical depth from an improved analysis of the High Frequency Instrument (HFI) data of Planck satellite. By using an improved versi…
Learning Latent Dynamics for Partially-Observed Chaotic Systems
Said Ouala, Duong Nguyen, Lucas Drumetz +5
This paper addresses the data-driven identification of latent dynamical representations of partially-observed systems, i.e., dynamical systems for which some components are never o…
Planck 2018 results. V. CMB power spectra and likelihoods
Planck Collaboration, N. Aghanim, Y. Akrami +165
This paper describes the 2018 Planck CMB likelihoods, following a hybrid approach similar to the 2015 one, with different approximations at low and high multipoles, and implementin…
SRoll2: an improved mapmaking approach to reduce large-scale systematic effects in the Planck High Frequency Instrument legacy maps
J. -M. Delouis, L. Pagano, S. Mottet +2
This paper describes an improved mapmaking approach with respect to the one used for the Planck High Frequency Instrument 2018 Legacy release. The algorithm SRoll2 better corrects…
