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…
Limits on Fast Radio Bursts at 145 MHz with ARTEMIS, a real-time software backend
A. Karastergiou, J. Chennamangalam, W. Armour +22
Fast Radio Bursts (FRBs), are millisecond radio signals that exhibit dispersion larger than what the Galactic electron density can account for. We have conducted a 1446 hour survey…
Monitoring young associations and open clusters with Kepler in two-wheel mode
S. Aigrain, S. Alencar, R. Angus +14
We outline a proposal to use the Kepler spacecraft in two-wheel mode to monitor a handful of young associations and open clusters, for a few weeks each. Judging from the experience…
Astrophysically robust systematics removal using variational inference: application to the first month of Kepler data
S. Roberts, A. McQuillan, S. Reece +1
Space-based transit search missions such as Kepler are collecting large numbers of stellar light curves of unprecedented photometric precision and time coverage. However, before th…
A GPU-based survey for millisecond radio transients using ARTEMIS
W. Armour, A. Karastergiou, M. Giles +7
Astrophysical radio transients are excellent probes of extreme physical processes originating from compact sources within our Galaxy and beyond. Radio frequency signals emitted fro…
