Radio variable and transient sources on minute time-scales in the ASKAP pilot surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 We present results from a radio survey for variable and transient sources on 15-min timescales, using the Australian SKA Pathfinder (ASKAP) pilot surveys.

Diverse origins for non-repeating fast radio bursts: Rotational radio transient sources and cosmological compact binary merger remnants [PDF]
Astronomy and Astrophysics, 2023 A large number of fast radio bursts (FRBs) detected with the CHIME telescope have enabled investigations of their energy distributions in different redshift intervals, incorporating the consideration of the selection effects of CHIME.

Cooperative Search of Multiple Unknown Transient Radio Sources Using Multiple Paired Mobile Robots [PDF]
IEEE Transactions on Robotics, 2014 We develop a localization method to enable a team of mobile robots to search for multiple unknown transient radio sources. Because of signal source anonymity, short transmission durations, and dynamic transmission patterns, robots cannot treat the radio sources as continuous radio beacons.

Decentralized searching of multiple unknown and transient radio sources
2013 IEEE International Conference on Robotics and Automation, 2013 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

Transient Sources in Astrophysics: From Radio to Gamma-Rays [PDF]
Proceedings of 3rd Annual Conference on High Energy Astrophysics in Southern Africa — PoS(HEASA2015), 2016 The enhanced sensitivity of a new generation of telescopes, from radio (meerKAT-SKA) to VHE Gamma-Rays (CTA), may provide the required sensitivity to detect and study very faint accretion driven transient phenomena from a plethora of sources.

VARIABLE AND TRANSIENT RADIO SOURCES IN THE FIRST SURVEY [PDF]
Astrophysical Journal, 2011 A comprehensive search for variable and transient radio sources has been conducted using ~55,000 snapshot images of the FIRST survey. We present an analysis leading to the discovery of 1,627 variable and transient objects down to mJy levels over a wide range of timescales (few minutes to years).

Identifying transient and variable sources in radio images [PDF]
Astronomy and Computing, 2019 With the arrival of a number of wide-field snapshot image-plane radio transient surveys, there will be a huge influx of images in the coming years making it impossible to manually analyse the datasets. Automated pipelines to process the information stored in the images are being developed, such as the LOFAR Transients Pipeline, outputting light curves ...

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.

TEMPORAL SMEARING OF TRANSIENT RADIO SOURCES BY THE INTERGALACTIC MEDIUM [PDF]
The Astrophysical Journal, 2013 The temporal smearing of impulsive radio events at cosmological redshifts probes the properties of the ionized intergalactic medium (IGM). We relate the degree of temporal smearing and the profile of a scattered source to the evolution of a turbulent ...

Simultaneous Localization of Multiple Unknown and Transient Radio Sources Using a Mobile Robot [PDF]
IEEE Transactions on Robotics, 2012 We report system and algorithm developments that utilize a single mobile robot to simultaneously localize multiple unknown transient radio sources. Because of signal source anonymity, short transmission durations, and dynamic transmission patterns, the robot cannot treat the radio sources as continuous radio beacons.
