Improved CLEAN reconstructions for rotation measure synthesis with maximum likelihood estimation
M. R. Bell, N. Oppermann, A. Crai +1
The CLEAN deconvolution algorithm has well-known limitations due to the restriction of locating point source model components on a discretized grid. In this letter we demonstrate t…
Reconstruction of Gaussian and log-normal fields with spectral smoothness
Niels Oppermann, Marco Selig, Michael R. Bell +1
We develop a method to infer log-normal random fields from measurement data affected by Gaussian noise. The log-normal model is well suited to describe strictly positive signals wi…
The XENON100 exclusion limit without considering Leff as a nuisance parameter
Jonathan H Davis, Celine Boehm, Niels Oppermann +2
In 2011, the XENON100 experiment has set unprecedented constraints on dark matter-nucleon interactions, excluding dark matter candidates with masses down to 6 GeV if the correspond…
