Performance characterization of a broadband vector Apodizing Phase Plate coronagraph
G. P. P. L. Otten, F. Snik, M. A. Kenworthy +2
One of the main challenges for the direct imaging of planets around nearby stars is the suppression of the diffracted halo from the primary star. Coronagraphs are angular filters t…
Laboratory formation of fullerenes from PAHs: Top-down interstellar chemistry
Junfeng Zhen, Pablo Castellanos, Daniel M. Paardekooper +2
Interstellar molecules are thought to build up in the shielded environment of molecular clouds or in the envelope of evolved stars. This follows many sequential reaction steps of a…
Measuring a Cherenkov ring in the radio emission from air showers at 110-190 MHz with LOFAR
A. Nelles, P. Schellart, S. Buitink +66
Measuring radio emission from air showers offers a novel way to determine properties of the primary cosmic rays such as their mass and energy. Theory predicts that relativistic tim…
On the Reliability of N-body Simulations
Tjarda Boekholt, Simon Portegies Zwart
The general consensus in the N-body community is that statistical results of an ensemble of collisional N-body simulations are accurate, even though individual simulations are not.…
The LOFAR long baseline snapshot calibrator survey
J. Moldón, A. T. Deller, O. Wucknitz +82
Aims. An efficient means of locating calibrator sources for International LOFAR is developed and used to determine the average density of usable calibrator sources on the sky for s…
A scheme for radiation pressure and photon diffusion with the M1 closure in RAMSES-RT
J. Rosdahl, R. Teyssier
We describe and test an updated version of radiation-hydrodynamics (RHD) in the RAMSES code, that includes three new features: i) radiation pressure on gas, ii) accurate treatment…
The Australian Square Kilometre Array Pathfinder: System Architecture and Specifications of the Boolardy Engineering Test Array
A. W. Hotan, J. D. Bunton, L. Harvey-Smith +98
This paper describes the system architecture of a newly constructed radio telescope - the Boolardy Engineering Test Array, which is a prototype of the Australian Square Kilometre A…
The Influence of Social Movements on Space Astronomy Policy
Hannah E. Harris, Pedro Russo
Public engagement (PE) initiatives can lead to a long term public support of science. However most of the real impact of PE initiatives within the context of long-term science poli…
A connected component-based method for efficiently integrating multiscale -body systems
Jürgen Jänes, Federico I. Pelupessy, Simon F. Portegies Zwart
We present a novel method for efficient direct integration of gravitational N-body systems with a large variation in characteristic time scales. The method is based on a recursive…
UVMag: Space UV and visible spectropolarimetry
Martin Pertenais, Coralie Neiner, Laurent Pares +3
UVMag is a project of a space mission equipped with a high-resolution spectropolarimeter working in the UV and visible range. This M-size mission will be proposed to ESA at its M4…
Lunar occultation of the diffuse radio sky: LOFAR measurements between 35 and 80 MHz
H. K. Vedantham, L. V. E. Koopmans, A. G. de Bruyn +91
We present radio observations of the Moon between and MHz to demonstrate a novel technique of interferometrically measuring large-scale diffuse emission extending far bey…
Gaia on-board metrology: basic angle and best focus
A. Mora, M. Biermann, A. G. A. Brown +21
The Gaia payload ensures maximum passive stability using a single material, SiC, for most of its elements. Dedicated metrology instruments are, however, required to carry out two f…
Fundamental limitations of high contrast imaging set by small sample statistics
Dimitri Mawet, Julien Milli, Zahed Wahhaj +9
In this paper, we review the impact of small sample statistics on detection thresholds and corresponding confidence levels (CLs) in high contrast imaging at small angles. When look…
Focal-plane wavefront sensing with high-order adaptive optics systems
Visa Korkiakoski, Christoph U. Keller, Niek Doelman +3
We investigate methods to calibrate the non-common path aberrations at an adaptive optics system having a wavefront-correcting device working at an extremely high resolution (large…
Big Data analytics and Cognitive Computing: future opportunities for Astronomical research
Michael Garrett
The days of the lone astronomer with his optical telescope and photographic plates are long gone: Astronomy in 2025 will not only be multi-wavelength, but multi-messenger, and domi…
Fast & Furious focal-plane wavefront sensing
Visa Korkiakoski, Christoph U. Keller, Niek Doelman +3
We present two complementary algorithms suitable for using focal-plane measurements to control a wavefront corrector with an extremely high spatial resolution. The algorithms use l…
LOFAR Sparse Image Reconstruction
