Interstellar Scintillations of Polarization of Compact Sources [PDF]

open access: yesThe Astrophysical Journal, 1999
We demostrate that the measurement of fluctuations of polarization due to the galactic interstellar scintillations may be used to study the structure of the radiation field at compact radio sources.

Interstellar Scintillation and Scattering of Micro-arc-second AGN

open access: yesGalaxies, 2016
The discovery of the first quasar 3C 273 led directly to the discovery of their variability at optical and radio wavelengths. We review the radio variability observations, in particular the variability found at frequencies below 1 GHz, as well as those ...

Interstellar Turbulence II: Implications and Effects

open access: yesAnnual Review of Astronomy and Astrophysics, 2004
Interstellar turbulence has implications for the dispersal and mixing of the elements, cloud chemistry, cosmic ray scattering, and radio wave propagation through the ionized medium.

Single-pulse-based Interstellar Scintillation Studies of RRATs

open access: yesThe Astrophysical Journal Letters
The nature of irregularly spaced pulses of rotating radio transients (RRATs) complicates interstellar scintillation studies. In this Letter, we report the primary scintillation parameters of a sample of RRATs using pairwise correlations of pulse spectra.

Microarcsecond Radio Imaging using Earth Orbit Synthesis [PDF]

open access: yes, 2001
The observed interstellar scintillation pattern of an intra-day variable radio source is influenced by its source structure. If the velocity of the interstellar medium responsible for the scattering is comparable to the earth's, the vector sum of these ...

Interstellar scintillation of an extreme scintillator: PKS B1144−379 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT The University of Tasmania Ceduna radio telescope has been used to investigate rapid variability in the radio flux density of the BL Lac object PKS B1144−379 at 6.7 GHz. High-cadence monitoring of this extreme scintillator was carried out over a period of approximately 9 yr, between 2003 and 2011.

On Detecting Interstellar Scintillation in Narrowband Radio SETI

open access: yesThe Astrophysical Journal, 2023
To date, the search for radio technosignatures has focused on sky location as a primary discriminant between technosignature candidates and anthropogenic radio frequency interference (RFI).

Technical Constraints on Interstellar Interferometry and Spatially Resolving the Pulsar Magnetosphere

open access: yesThe Astrophysical Journal, 2023
Scintillation of pulsar radio signals caused by the interstellar medium can in principle be used for interstellar interferometry. Changes in the dynamic spectra as a function of pulsar longitude were in the past interpreted as having spatially resolved ...
