Fast Calculation of the Lomb-Scargle Periodogram Using Graphics Processing Units
I introduce a new code for fast calculation of the Lomb-Scargle periodogram, that leverages the computing power of graphics processing units (GPUs). After establishing a background to the newly emergent field of GPU computing, I discuss the code design and narrate the key parts of the source. Ben...Tags: instrumentation and methods for astrophysics, arxiv, apj, gpu, monte-carlo simulation, periodogram

- We describe a Phased Array Feed (PAF) system, called Apertif, which will be installed in the Westerbork Synthesis Radio Telescope (WSRT). The aim of Apertif is, at frequencies from 1.0 to 1.7 GHz, to increase the instantaneous field of view of the WSRT 8 deg^2 and its observing bandwidth to 300 M...

GASKAP -- A Galactic Spectral Line Survey with the Australian Square Kilometre Array Pathfinder
One of the Survey Science Projects that the Australian Square Kilometre Array Pathfinder (ASKAP) telescope will do in its first few years of operation is a study of the 21-cm line of HI and the 18-cm lines of OH in the Galactic Plane and the Magellanic Clouds and Stream. The wide-field ASKAP can ...Tags: galaxy astrophysics, instrumentation and methods for astrophysics, arxiv, the dynamic ism: a celebration of the canadian galactic plane survey

Progress with the LOFAR Imaging Pipeline
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 interferometric data, such that fully calibrated images are produced by the system during survey operations. The LOFAR I...Tags: iskaf2010 science meeting, instrumentation and methods for astrophysics, arxiv

The True Bottleneck of Modern Scientific Computing in Astronomy
We discuss what hampers the rate of scientific progress in our exponentially growing world. The rapid increase in technologies leaves the growth of research result metrics far behind. The reason for this lies in the education of astronomers lacking basic computer science aspects crucially importa...Tags: instrumentation and methods for astrophysics
