Generalized massive optimal data compression
Justin Alsing, Benjamin Wandelt
Data compression has become one of the cornerstones of modern astronomical data analysis, with the vast majority of analyses compressing large raw datasets down to a manageable num…
Bayesian delensing of CMB temperature and polarization
Marius Millea, Ethan Anderes, Benjamin D. Wandelt
We develop the first algorithm able to jointly compute the maximum {\it a posteriori} estimate of the Cosmic Microwave Background (CMB) temperature and polarization fields, the gra…
Measuring Polarized Emission in Clusters in the CMB S4 Era
Thibaut Louis, Emory F. Bunn, Benjamin Wandelt +1
The next generation of CMB experiments (CMB Stage-4) will produce a Sunyaev-Zel'dovich (SZ) cluster catalog containing objects, two orders of magnitudes more than curr…
Planck intermediate results. LIII. Detection of velocity dispersion from the kinetic Sunyaev-Zeldovich effect
Planck Collaboration, N. Aghanim, Y. Akrami +141
Using the full-mission data, we present a detection of the temperature (and therefore velocity) dispersion due to the kinetic Sunyaev-Zeldovich (kSZ) effect from clu…
Wiener filter reloaded: fast signal reconstruction without preconditioning
Doogesh Kodi Ramanah, Guilhem Lavaux, Benjamin D. Wandelt
We present a high performance solution to the Wiener filtering problem via a formulation that is dual to the recently developed messenger technique. This new dual messenger algorit…
Void profile from Planck lensing potential map
Teeraparb Chantavat, Utane Sawangwit, Benjamin D. Wandelt
We use the lensing potential map from Planck CMB lensing reconstruction analysis and the "Public Cosmic Void Catalog" to measure the stacked void lensing potential. In this profile…
