Limits on Fast Radio Bursts and other transient sources at 182 MHz using the Murchison Widefield Array [PDF]
, 2016 We present a survey for transient and variable sources, on time-scales from 28 s to ∼1 yr, 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 ...

Transient Sources in Astrophysics: From Radio to Gamma-Rays [PDF]
, 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.

TEMPORAL SMEARING OF TRANSIENT RADIO SOURCES BY THE INTERGALACTIC MEDIUM [PDF]
, 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 ...

Two extreme steep-spectrum, polarized radio sources towards the Galactic bulge [PDF]
Monthly notices of the Royal Astronomical Society, 2021 From an on-going survey of the Galactic bulge, we have discovered a number of compact, steep spectrum radio sources. In this study, we have carried out more detailed observations for two of these sources, located 43 arcmin and 12${_{.}^{\circ}}$7 from ...

The hybrid radio/X-ray correlation of the black hole transient MAXI J1348–630 [PDF]
, 2021 Black hole low mass X-ray binaries in their hard spectral state are found to display two different correlations between the radio emission from the compact jets and the X-ray emission from the inner accretion flow.

Calculation and Uncertainty of Fast Radio Burst Structure Based on Smoothed Data
The Astrophysical Journal, 2023 Studies of the time-domain structure of fast radio bursts (FRBs) require an accurate estimate of the FRB dispersion measure in order to recover the intrinsic burst shape.
