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…
M87 at metre wavelengths: the LOFAR picture
F. de Gasperin, E. Orru', M. Murgia +92
M87 is a giant elliptical galaxy located in the centre of the Virgo cluster, which harbours a supermassive black hole of mass 6.4x10^9 M_sun, whose activity is responsible for the…
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…
Simulation of stochastic network dynamics via entropic matching
Tiago Ramalho, Marco Selig, Ulrich Gerland +1
The simulation of complex stochastic network dynamics arising, for instance, from models of coupled biomolecular processes remains computationally challenging. Often, the necessity…
Planck Intermediate Results. IX. Detection of the Galactic haze with Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +181
Using precise full-sky observations from Planck, and applying several methods of component separation, we identify and characterize the emission from the Galactic "haze" at microwa…
Planck intermediate results. X. Physics of the hot gas in the Coma cluster
Planck Collaboration, P. A. R. Ade, N. Aghanim +207
We present an analysis of Planck satellite data on the Coma Cluster observed via the Sunyaev-Zeldovich effect. Planck is able, for the first time, to detect SZ emission up to r ~ 3…
