A Framework for Assessing the Performance of Pulsar Search Pipelines
E. van Heerden, A. Karastergiou, S. J. Roberts
In this paper, we present a framework for assessing the effect of non-stationary Gaussian noise and radio frequency interference (RFI) on the signal to noise ratio, the number of f…
Simultaneous radio and X-ray observations of PSR B0611+22
Kaustubh Rajwade, Andrew Seymour, Duncan R Lorimer +4
We report results from simultaneous radio and X-ray observations of PSR B0611+22 which is known to exhibit bursting in its single-pulse emission. The pulse phase of the bursts vary…
HIRAX: A Probe of Dark Energy and Radio Transients
L. B. Newburgh, K. Bandura, M. A. Bucher +33
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a new 400-800MHz radio interferometer under development for deployment in South Africa. HIRAX will comprise 1024…
The frequency dependence of scattering imprints on pulsar observations
Marisa Geyer, Aris Karastergiou
Observations of pulsars across the radio spectrum are revealing a dependence of the characteristic scattering time () on frequency, which is more complex than the simple power l…
A large light-mass component of cosmic rays at 10^{17} - 10^{17.5} eV from radio observations
S. Buitink, A. Corstanje, H. Falcke +101
Cosmic rays are the highest energy particles found in nature. Measurements of the mass composition of cosmic rays between 10^{17} eV and 10^{18} eV are essential to understand whet…
Characterization of a dense aperture array for radio astronomy
S. A. Torchinsky, A. O. H. Olofsson, B. Censier +5
EMBRACE@Nancay is a prototype instrument consisting of an array of 4608 densely packed antenna elements creating a fully sampled, unblocked aperture. This technology is proposed fo…
