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, scattering and scintillation. Our analysis applies to the giant-pulse phenomenon exhibited by some pulsars, for which we show examples, and to radio pulses from other astrophysical sources, such as prompt r...
متن کاملRadio Frequency Interference and Detection of Fast Radio Transients
Exploring the transient radio sky is one of the major science drivers for several upcoming and planned radio telescopes, including the Square Kilometer Array (SKA). The detection of transient signals, particularly of relatively short durations, can however be considerably hampered by the prevalent and ever growing problem of radio frequency interference (RFI) in radio astronomy. With the goal o...
متن کاملBayesian detection of radio transmitter turn-on transients
This paper describes an implementation of Bayesian change point detection for extracting transients captured from radio transmitter transmissions. When a radio transmitter is activated, it goes through a relatively short transient phase during which the signals generated by the unit have characteristics that can be unique. If these turnon transients can be separated, they can be analyzed to ide...
متن کاملSubmilliJansky Transients in Archival Radio Observations
We report the results of a 944-epoch survey for transient sources with archival data from the Very Large Array spanning 22 years with a typical epoch separation of 7 days. Observations were obtained at 5 or 8.4 GHz for a single field of view with a full-width at half-maximum of 8.6 and 5.1, respectively, and achieved a typical point-source detection threshold at the beam center of ∼< 300 μJy pe...
متن کاملPhysical Interpretations of Rotating Radio Transients
Nearly a dozen of Rotating RAdio Transients (RRATs) have been discovered recently. These objects share similar spin parameters with normal radio pulsars but distinguish themselves from normal pulsars by being quiescent most of the time and only becoming radio bright occasionally. We discuss two possible interpretations to the phenomenon. The first model suggests that these objects are pulsars s...
