The Denoised, Deconvolved, and Decomposed Fermi -ray sky - An application of the DPO algorithm
Marco Selig, Valentina Vacca, Niels Oppermann +1
We analyze the 6.5yr all-sky data from the Fermi LAT restricted to gamma-ray photons with energies between 0.6-307.2GeV. Raw count maps show a superposition of diffuse and point-li…
Planck intermediate results. XXXII. The relative orientation between the magnetic field and structures traced by interstellar dust
Planck Collaboration, R. Adam, P. A. R. Ade +199
The role of the magnetic field in the formation of the filamentary structures observed in the interstellar medium (ISM) is a debated topic. The Planck all-sky maps of linearly pola…
Bayesian CMB foreground separation with a correlated log-normal model
Niels Oppermann, Torsten A. Enßlin
The extraction of foreground and CMB maps from multi-frequency observations relies mostly on the different frequency behavior of the different components. Existing Bayesian methods…
Planck intermediate results. XXII. Frequency dependence of thermal emission from Galactic dust in intensity and polarization
Planck Collaboration, P. A. R. Ade, M. I. R. Alves +177
Planck has mapped the intensity and polarization of the sky at microwave frequencies with unprecedented sensitivity. We make use of the Planck 353 GHz I, Q, and U Stokes maps as du…
Estimating extragalactic Faraday rotation
Niels Oppermann, Henrik Junklewitz, Maksim Greiner +11
(abridged) Observations of Faraday rotation for extragalactic sources probe magnetic fields both inside and outside the Milky Way. Building on our earlier estimate of the Galactic…
A Wideband Polarization Survey of the Extragalactic Sky at 2-4 GHz: A Science White Paper for the VLA Sky Survey
Sui Ann Mao, Julie Banfield, Bryan Gaensler +23
A VLA Sky Survey of the extragalactic sky at S band (2-4 GHz) with polarization information can uniquely probe the magneto-ionic medium in a wide range of astrophysical environment…
