Interstellar scintillation and the interstellar turbulent plasma

Astronomical and Astrophysical Transactions, 2002
Data on interstellar diffractive and refractive scintillation of pulsars are analyzed. The comparison between the theory and the observational data shows that two types of spectra for electron density fluctuations are realized in the interstellar medium: simple power law and piecewise with a break. The distribution of turbulent plasma in the Galaxy has

Interstellar scintillation and pulsar velocities

Nature, 1982
Interstellar scintillation of the intensity of pulsar radio signals is known to be the effect of diffraction in random irregularities in electron density, with typical scales of 1013 cm and density fluctuations of typically 3×10−4 cm−3. The observed fading pattern is believed to be due to the combined motion of the pulsar and the observer relative to ...

Interstellar scintillation: observational highlights

Astronomical and Astrophysical Transactions, 2007
This paper reviews the chief observational phenomena that define interstellar scintillation (ISS) and have given evidence for a widespread distribution of plasma turbulence on very small scales. Though ISS was discovered in pulsars and is still a major perturbation of their signals, it is now also recognized in a variety of fluctuations in the flux ...

Review of theory of interplanetary and interstellar scintillation

Astronomical and Astrophysical Transactions, 2007
Basic theoretical methods and solutions describing radio wave propagation in the turbulent plasma are briefly reviewed. Consideration is given to the results on scattering effects such as angular scattering, pulse broadening and spectral line spread. Also treated are phase and frequency fluctuations.

Interstellar scintillation, ISS, and intrinsic variability of radio AGN [PDF]

Advances in Space Research, 2020
We investigate the relationship between the 5 GHz interstellar scintillation (ISS) and the 15 GHz intrinsic variability of the compact, radio-selected active galactic nuclei (AGN) common to the Microarcsecond Scintillation-Induced Variability (MASIV ...

Pulsar scintillation and the local interstellar medium [PDF]

, 2000
Ever since their discovery, pulsars have been proved to be excellent tools to study the Interstellar Medium. Results from new observations using the Ooty Radio Telescope at 327 MHz are used to investigate the properties of the Local Interstellar Medium; in particular, the distribution of radio wave scattering material and the spatial power spectrum of ...
