Accelerating radio transient detection using the Bispectrum algorithm and GPGPU
Modern radio interferometers such as those in the Square Kilometre Array (SKA) project are powerful tools to discover completely new classes of astronomical phenomena. Amongst these phenomena are radio transients. Transients are bursts of electromagnetic radiation and is an exciting area of …

A Dedicated Search for Low Frequency Radio Transient Astrophysical Events using ETA
… pulses detectable in the low end of the radio spectrum. Analysis of these pulses could provide valuable information about the sources, and the surrounding and intervening medium. The Eight-meter-wavelength Transient Array (ETA) is a radio telescope dedicated to the search for these pulses …

Sampling the Radio Transient Universe: Studies of Pulsars and the Search for Extraterrestrial Intelligence
The transient radio universe is a relatively unexplored area of astronomy, offering a variety of phenomena, from solar and Jovian bursts, to flare stars, pulsars, and bursts of Galactic and potentially even cosmological origin. Among these, perhaps the most widely studied radio transients, pulsars …

A matched filter technique for slow radio transient detection and first demonstration with the Murchison Widefield Array
Many astronomical sources produce transient phenomena at radio frequencies, but the transient sky at low frequencies (< 300 MHz) remain relatively unexplored. Blind surveys with new widefield radio instruments are filling this gap. Although many of these instruments are limited by the classical …

Commensal searches for radio transients variables in the data from Mhongoose Large Survey Project
The MeerKAT radio telescope in South Africa, a precursor to the mid-frequency component of the Square Kilometre Array (SKA1-Mid), offers exceptional sensitivity and a wide field of view, making it ideal for exploring time-domain radio astronomy. This dissertation presents the use of MeerKAT images …

Classification of multiwavelength transients with machine learning
… we are entering a golden era of multiwavelength transient astronomy. The large MeerKAT science project ThunderKAT may dramatically increase the detected number of radio transients. Currently radio transient datasets are still very small, allowing spectroscopic classification of all objects of …

A Search for Astrophysical Radio Transients at Meter Wavelengths
… detectable at the low-frequency end of the radio spectrum. Detection of any of these pulses would be significant for the study of the objects themselves, their host environments, and the interstellar/intergalactic medium. Furthermore, a detection of a radio transient from an exploding PBH …

Searches for Radio Transients using the Long Wavelength Array
… pulses (GPs) from pulsars and search for other radio transients. Using the LWA with a bandwidth of 16 MHz at 39 MHz, we made a 24-hour observation of pulsar radio pulses from PSR B0950+08. The average pulse ux density and pulse width (dominated by "normal" pulses) are consistent with previous …
