New radio facilities, such as the EVLA/VLBA, eMERLIN, LOFAR and eVLBI on the EVN, will revolutionise the study of radio-quiet AGN; in particular, the combination of increased sensitivity and sampling rate with high-angular resolution and automatic data reduction will open up the transient radio sky and bring major future breakthroughs. Radio Transients Did you know? The SKA will be able to survey the sky at a rate faster than any survey telescope that has ever existed. When RRATs burst onto the scene in 2006, it was thought that they represented a previously unknown, distinct class of sporadically emitting sources. A Complete Survey of the Transient Radio Sky and Implications for Gamma-Ray Bursts, Supernovae, and other Relativistic Explosions Avishay Gal-Yam1 arXiv:astro-ph/0508629v1 29 Aug 2005 Astronomy Department, MS 105-24, California Institute of Technology, Pasadena, CA 91125 avishay@astro.caltech.edu Eran O. Ofek, Dovi Poznanski, Amir Levinson School of Physics & … Artist’s composite of the CSIRO’s 64-metre Parkes radio telescope showing an extragalactic radio burst appearing briefly, far from the Milky Way’s disk. In addition, some of the initially identified RRATs were observed with the Lovell Telescope at Jodrell Bank. 2016 The Astrophysical Journal 831 190. Characterising the Transient Radio Sky with SKA Precursors The Square Kilometre Array (SKA) will mark a revolution in radio astronomy; through its large collecting area and novel design, it will excel in sensitivity and open a new window onto the universe. The Parkes Multi-beam Pulsar Survey, wherein the RRATs were initially identified, offered an opportunity to do just this. Of these, 12 have been re-detected on multiple occasions, whereas the others have not been seen to re-emitsince the initial discovery observations, and may be very low burst-rate RRATs, or, isolated burst events. The Transient Radio Sky Seminar. The high time-resolution radio sky represents unexplored astronomical territory. Observations of this wide variety of sources are relevant to many of the highest profile questions in astronomy and astrophysics. As such, the work is concerned primarily with neutron stars. This thesis addresses the topic of exploring and characterising the transient and variable radio sky, using both existing radio telescopes, and the next generation of radio facilities such as the Low Frequency Array (LOFAR). These transients have an implied all-sky rate that would make them the most common radio transient in the sky and yet most have no quiescent counterparts at other wavelengths and therefore no known progenitor (other than Galactic neutron … As such, this work is concerned primarily with neutron stars, the most populous member of the radio transient parameter space. The observations have also been used to perform`timing' observations of RRATs, i.e. We report on a re-analysis of archival data from the Very Large Array for a sample of ten long duration radio transients reported by Bower and others. Of these, 12 have been seen to repeat and a followup campaign of observations has been undertaken. We have a dedicated site for USA, Authors: The high time-resolution radio sky represents unexplored astronomical territory.

Exploring the Transient Radio Sky with VLITE: Early Results E. Polisensky et al. JavaScript is currently disabled, this site works much better if you This thesis presents a study of the transient radio sky, focussing on millisecond scales. After analysing neutron star birthrates, a re-analysis of the Parkes Multibeam Pulsar Survey is described which has resulted in the discovery of 19 new transient radio sources. rate with high-angular resolution and automatic data reduction will open up the transient radio sky and bring major future breakthroughs.
