A 22-yr southern sky survey for transient and variable radio sources using the Molonglo Observatory Synthesis Telescope [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We describe a 22-year survey for variable and transient radio sources, performed with archival images taken with the Molonglo Observatory Synthesis Telescope (MOST). This survey covers $2775 \unit{deg^2}$ of the sky south of $ < -30\degree$ at an observing frequency of 843 MHz, an angular resolution of $45 \times 45 \csc | | \unit{arcsec^2}$ and ...

Direct Imaging Digital Lens for Transient Radio Source Survey [PDF]
International Astronomical Union Colloquium, 1991 AbstractFFT based 2D Dygital Lens is discussed comparing with Fourier synthesis. The sensitivity of constructing Large Array will be 50mJy. Precise manipuration of the radiation field is possible in it.

A radio survey of supersoft, persistent and transient X-ray sources in the Magellanic Clouds [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We present a radio survey of X-ray sources in the Large and Small Magellanic clouds with the Australia Telescope Compact Array at 6.3 and 3.5 cm. Specifically, we have observed the fields of five LMC and two SMC supersoft X-ray sources, the X-ray binaries LMC X-1, X-2, X-3 & X-4, the X-ray transient Nova SMC 1992, and the soft gamma-ray repeater ...

A new method for short-duration transient detection in radio images: searching for transient sources in MeerKAT data of NGC 5068 [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT Transient surveys are a vital tool in exploring the dynamic Universe, with radio transients acting as beacons for explosive and highly energetic astrophysical phenomena. However, performing commensal transient surveys using radio imaging can require a significant amount of computing power, data storage, and time.

Limits on Fast Radio Bursts and other transient sources at 182 MHz using the Murchison Widefield Array [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We present a survey for transient and variable sources, on timescales from 28 seconds to $\sim$1 year, using the Murchison Widefield Array (MWA) at 182 MHz. Down to a detection threshold of 0.285 Jy, no transient candidates were identified, making this the most constraining low-frequency survey to date and placing a limit on the surface density of ...

A search for variable and transient radio sources in the extended Chandra Deep Field South at 5.5 GHz [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We present a three epoch survey for transient and variables in the extended Chandra Deep Field South at 5.5 GHz with the Australia Telescope Compact Array. A region covering $\sim$0.3 deg$^{2}$ was observed on timescales of 2.5 months and 2.5 years and typical sensitivities 12.1 $-$ 17.1 $ $Jy beam$^{-1}$ (1$ $) were achieved.

MULTI-MESSENGER ASTRONOMY OF GRAVITATIONAL-WAVE SOURCES WITH FLEXIBLE WIDE-AREA RADIO TRANSIENT SURVEYS [PDF]
The Astrophysical Journal, 2015 We explore opportunities for multi-messenger astronomy using gravitational waves (GWs) and prompt, transient low-frequency radio emission to study highly energetic astrophysical events. We review the literature on possible sources of correlated emission of gravitational waves and radio transients, highlighting proposed mechanisms that lead to a short ...

A SEARCH FOR RAPIDLY SPINNING PULSARS AND FAST TRANSIENTS IN UNIDENTIFIED RADIO SOURCES WITH THE NRAO 43 METER TELESCOPE [PDF]
The Astronomical Journal, 2013 We have searched 75 unidentified radio sources selected from the NRAO VLA Sky Survey (NVSS) catalog for the presence of rapidly spinning pulsars and short, dispersed radio bursts. The sources are radio bright, have no identifications or optical source coincidences, are more than 5% linearly polarized, and are spatially unresolved in the catalog.

Decentralized Searching of Multiple Unknown and Transient Radio Sources with Paired Robots
Engineering, 2015 ABSTRACTIn this paper, we develop a decentralized algorithm to coordinate a group of mobile robots to search for unknown and transient radio sources. In addition to limited mobility and ranges of communication and sensing, the robot team has to deal with challenges from signal source anonymity, short transmission duration, and variable transmission ...
