Survey-scale discovery-based research processes: Evaluating a bespoke visualisation environment for astronomical survey data
C. J. Fluke, D. Vohl, V. A. Kilborn +1
Next generation astronomical surveys naturally pose challenges for human-centred visualisation and analysis workflows that currently rely on the use of standard desktop display env…
Apertif 1.4 GHz continuum observations of the Boötes field and their combined view with LOFAR
A. M. Kutkin, T. A. Oosterloo, R. Morganti +17
We present a new image of a 26.5 square degree region in the Boötes constellation obtained at 1.4 GHz using the Aperture Tile in Focus (Apertif) system on the Westerbork Synthesis…
An interference detection strategy for Apertif based on AOFlagger 3
A. R. Offringa, B. Adebahr, A. Kutkin +15
Context. Apertif is a multi-beam receiver system for the Westerbork Synthesis Radio Telescope that operates at 1.1-1.5 GHz, which overlaps with various radio services, resulting in…
Continuum source catalog for the first APERTIF data release
A. M. Kutkin, T. A. Oosterloo, R. Morganti +25
The first data release of Apertif survey contains 3074 radio continuum images covering a thousand square degrees of the sky. The observations were performed during August 2019 to J…
First release of Apertif imaging survey data
Elizabeth A. K. Adams, B. Adebahr, W. J. G. de Blok +56
(Abridged) Apertif is a phased-array feed system for WSRT, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated survey program started on 1 July 2019, with th…
Apercal -- The Apertif Calibration Pipeline
B. Adebahr, R. Schulz, T. J. Dijkema +33
Apertif (APERture Tile In Focus) is one of the Square Kilometre Array (SKA) pathfinder facilities. The Apertif project is an upgrade to the 50-year-old Westerbork Synthesis Radio T…
Real-Time RFI Mitigation for the Apertif Radio Transient System
Alessio Sclocco, Dany Vohl, Rob V. van Nieuwpoort
Current and upcoming radio telescopes are being designed with increasing sensitivity to detect new and mysterious radio sources of astrophysical origin. While this increased sensit…
The Growing Importance of a Tech Savvy Astronomy and Astrophysics Workforce
Dara Norman, Kelle Cruz, Vandana Desai +26
Fundamental coding and software development skills are increasingly necessary for success in nearly every aspect of astronomical and astrophysical research as large surveys and hig…
Enabling near real-time remote search for fast transient events with lossy data compression
Dany Vohl, Tyler Pritchard, Igor Andreoni +2
We present a systematic evaluation of JPEG2000 (ISO/IEC 15444) as a transport data format to enable rapid remote searches for fast transient events as part of the Deeper Wider Fast…
Real-time colouring and filtering with graphics shaders
Dany Vohl, Christopher J. Fluke, David G. Barnes +1
Despite the popularity of the Graphics Processing Unit (GPU) for general purpose computing, one should not forget about the practicality of the GPU for fast scientific visualisatio…
Collaborative workspaces to accelerate discovery
Bernard Meade, Christopher Fluke, Jeff Cooke +13
By applying a display ecology to the {\em Deeper, Wider, Faster} proactive, simultaneous telescope observing campaign, we have shown a dramatic reduction in the time taken to inspe…
Collaborative visual analytics of radio surveys in the Big Data era
Dany Vohl, Christopher J. Fluke, Amr H. Hassan +2
Radio survey datasets comprise an increasing number of individual observations stored as sets of multidimensional data. In large survey projects, astronomers commonly face limitati…
An interactive, comparative and quantitative 3D visualization system for large-scale spectral-cube surveys using CAVE2
Dany Vohl, Christopher J. Fluke, Amr H. Hassan +1
As the quantity and resolution of spectral-cubes from optical/infrared and radio surveys increase, desktop-based visualization and analysis solutions must adapt and evolve. Novel i…
Data Compression in the Petascale Astronomy Era: a GERLUMPH case study
Dany Vohl, Christopher J. Fluke, Georgios Vernardos
As the volume of data grows, astronomers are increasingly faced with choices on what data to keep -- and what to throw away. Recent work evaluating the JPEG2000 (ISO/IEC 15444) sta…
GERLUMPH Data Release 2: 2.5 billion simulated microlensing light curves
Georgios Vernardos, Christopher J. Fluke, Nicholas F. Bate +2
In the upcoming synoptic all--sky survey era of astronomy, thousands of new multiply imaged quasars are expected to be discovered and monitored regularly. Light curves from the ima…
