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 LOFAR radio environment
A. R. Offringa, A. G. de Bruyn, S. Zaroubi +93
Aims: This paper discusses the spectral occupancy for performing radio astronomy with the Low-Frequency Array (LOFAR), with a focus on imaging observations. Methods: We have analys…
The Atacama Cosmology Telescope: Data Characterization and Map Making
Rolando Dünner, Matthew Hasselfield, Tobias A. Marriage +71
We present a description of the data reduction and mapmaking pipeline used for the 2008 observing season of the Atacama Cosmology Telescope (ACT). The data presented here at 148 GH…
ArtDeco: A beam deconvolution code for absolute CMB measurements
Elina Keihänen, Martin Reinecke
We present a method for beam deconvolution for cosmic microwave background (CMB) anisotropy measurements. The code takes as input the time-ordered data, along with the correspondin…
The Ninth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Baryon Oscillation Spectroscopic Survey
III Collaboration, Christopher P. Ahn, Rachael Alexandroff +224
The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS…
A divergence-cleaning scheme for cosmological SPMHD simulations
F. A. Stasyszyn, K. Dolag, A. M. Beck
In magnetohydrodynamics (MHD), the magnetic field is evolved by the induction equation and coupled to the gas dynamics by the Lorentz force. We perform numerical smoothed particle…
INTEGRAL/IBIS nine-year Galactic Hard X-Ray Survey
R. Krivonos, S. Tsygankov, A. Lutovinov +3
Context. The INTEGRAL observatory operating in a hard X-ray/gamma domain has gathered a large observational data set over nine years starting in 2003. Most of the observing time wa…
Imaging the heart of astrophysical objects with optical long-baseline interferometry
J. -P. Berger, F. Malbet, F. Baron +21
The number of publications of aperture-synthesis images based on optical long-baseline interferometry measurements has recently increased due to easier access to visible and infrar…
The relative significance of the H-index
H. C. Spruit
Use of the Hirsch-index () as measure of an author's visibility in the scientific literature has become popular as an alternative to a gross measure like total citations (c). I…
