Monitoring the Sky with the Prototype All-Sky Imager on the LWA1
We present a description of the Prototype All-Sky Imager (PASI), a backend correlator and imager of the first station of the Long Wavelength Array (LWA1). PASI cross-correlates a live stream of 260…

THE ALLEN TELESCOPE ARRAY FLY'S EYE SURVEY FOR FAST RADIO TRANSIENTS
The relatively unexplored fast radio transient parameter space is known to be home to a variety of interesting sources, including pulsars, pulsar giant pulses, and non-thermal emission from planetary…
Enabling a high throughput real time data pipeline for a large radio telescope array with GPUs
- Computer Science, PhysicsComput. Phys. Commun.
This work describes a scalable heterogeneous computing pipeline implementation, exploiting both the high computing density and FLOP-perWatt ratio of modern GPUs.
Searches for Fast Radio Transients
We discuss optimal detection of fast radio transients from astrophysical objects while taking into account the effects of propagation through intervening ionized media, including dispersion,…
LOW FREQUENCY RADIO PULSES FROM GAMMA-RAY BURSTS?
Gamma-ray bursts, if they are generated by relativis- tic strongly magnetized winds, may be accompanied by very short pulses of low-frequency radio emission. The bulk of this emission is expected to…
LOFAR and APERTIF Surveys of the Radio Sky: Probing Shocks and Magnetic Fields in Galaxy Clusters
At very low frequencies, the new pan-European radio telescope LOFAR is opening the last unexplored window of the electromagnetic spectrum for astrophysical studies. The revolutionary APERTIF- phased…
Observing pulsars and fast transients with LOFAR
Low frequency radio waves, while challenging to observe, are a rich source of information about pulsars. The LOw Frequency ARray (LOFAR) is a new radio interferometer operating in the lowest 4…
Radio Remnants of Compact Binary Mergers - the Electromagnetic Signal that will follow the Gravitational Waves
The question “what is the observable electromagnetic (EM) signature of a compact binary merger?” is an intriguing one with crucial consequences to the quest for gravitational waves (GW). Compact…
