Stellar metallicities beyond the Local Group: the potential of J-band spectroscopy with extremely large telescopes
C. J. Evans, B. Davies, R. -P. Kudritzki +7
We present simulated J-band spectroscopy of red giants and supergiants with a 42m European Extremely Large Telescope (E-ELT), using tools developed toward the EAGLE Phase A instrum…
Libpsht - algorithms for efficient spherical harmonic transforms
Martin Reinecke
Libpsht (or "library for Performant Spherical Harmonic Transforms") is a collection of algorithms for efficient conversion between spatial-domain and spectral-domain representation…
Progress with the LOFAR Imaging Pipeline
George Heald, John McKean, Roberto Pizzo +14
One of the science drivers of the new Low Frequency Array (LOFAR) is large-area surveys of the low-frequency radio sky. Realizing this goal requires automated processing of the int…
Probing magnetic helicity with synchrotron radiation and Faraday rotation
N. Oppermann, H. Junklewitz, G. Robbers +1
We present a first application of the recently proposed LITMUS test for magnetic helicity, as well as a thorough study of its applicability under different circumstances. In order…
Imprints of magnetic power and helicity spectra on radio polarimetry statistics
H. Junklewitz, T. A. Enßlin
Statistical properties of turbulent magnetic fields in radio-synchrotron sources should imprint on the statistics of polarimetric observables. In search of these imprints, we calcu…
The 2010 Interferometric Imaging Beauty Contest
Fabien Malbet, William Cotton, Gilles Duvert +9
We present the results of the fourth Optical/IR Interferometry Imaging Beauty Contest. The contest consists of blind imaging of test data sets derived from model sources and distri…
INTEGRAL/IBIS 7-year All-Sky Hard X-Ray Survey. Part I: Image Reconstruction
R. Krivonos, M. Revnivtsev, S. Tsygankov +5
This paper is the first in a series devoted to the hard X-ray whole sky survey performed by the INTEGRAL observatory over seven years. Here we present an improved method for image…
eROSITA on SRG: a X-ray all-sky survey mission
N. Cappelluti, P. Predehl, H. Boehringer +23
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the core instrument on the Russian Spektrum-Roentgen-Gamma (SRG) mission which is scheduled for launch in late…
Inference with minimal Gibbs free energy in information field theory
Torsten A. Ensslin, Cornelius Weig
Non-linear and non-Gaussian signal inference problems are difficult to tackle. Renormalization techniques permit us to construct good estimators for the posterior signal mean withi…
An axis-free overset grid in spherical polar coordinates for simulating 3D self-gravitating flows
Annop Wongwathanarat, Nicolay J. Hammer, Ewald Müller
A type of overlapping grid in spherical coordinates called the Yin-Yang grid is successfully implemented into a 3D version of the explicit Eulerian grid-based code PROMETHEUS inclu…
Algorithm for the evaluation of reduced Wigner matrices
Gary Prezeau, Martin Reinecke
Algorithms for the fast and exact computation of Wigner matrices are described and their application to a fast and massively parallel 4pi convolution code between a beam and a sky…
Reconstruction of signals with unknown spectra in information field theory with parameter uncertainty
Torsten Ensslin, Mona Frommert
The optimal reconstruction of cosmic metric perturbations and other signals requires knowledge of their power spectra and other parameters. If these are not known a priori, they ha…
Planck pre-launch status: Design and description of the Low Frequency Instrument
M. Bersanelli, N. Mandolesi, R. C. Butler +109
In this paper we present the Low Frequency Instrument (LFI), designed and developed as part of the Planck space mission, the ESA program dedicated to precision imaging of the cosmi…
