Frequency-dependent brightness fluctuations of radio sources, the so-called extreme scattering events (ESEs), have been observed over the last three decades. They are caused by Galactic plasma structures whose geometry and origin are still poorly understood. In this paper, we construct axisymmentric two-dimensional (2D) column density profiles for the plasma lens and explore the resulting ESEs for both point-like and extended sources. A quantity that becomes relevant is the impact parameter $b…

In contrast to the converging, achromatic behaviour of axisymmetric gravitational lenses, diverging frequency-dependent lensing occurs from refraction due to a distribution of over-dense axisymmetric
Imaginary images and Stokes phenomena in the weak plasma lensing of coherent sources
The study of astrophysical plasma lensing, such as in the case of extreme scattering events, has typically been conducted using the geometric limit of optics, neglecting wave effects. However, for

Plasma lensing is the refraction of low-frequency electromagnetic rays due to free electrons in the interstellar medium. Although the phenomenon has a distinct similarity to gravitational lensing,

Gravitational microlensing has become a mature technique for discovering small gravitational lenses in the Universe that are otherwise beyond our detection limits. Similarly, plasma microlensing
Magnetized filament models for diverging plasma lenses
Spherical plasma lens models are known to suffer from a severe over-pressure problem, with some observations requiring lenses with central pressures up to millions of times in excess of the ambient
The Effects of Plasma Lensing on the Inferred Dispersion Measures of Fast Radiobursts
Radio signals are delayed when propagating through plasma. This type of delay is frequency-dependent and is usually used for estimating the projected number density of electrons along the line of
A comparison of interferometric and single-dish methods to measure distances to pulsar scattering screens
Investigations of small-scale structure in the interstellar medium through pulsar scintillation and the use of scattering screens as interferometers to resolve pulsar emission regions rely on
Disentangling interstellar plasma screens with pulsar VLBI: combining auto- and cross-correlations
Current methods of measuring distances to pulsar scattering screens rely on a single screen dominating the scintillation pattern. We present a novel technique to reconstruct the scattered flux of a
Plasma-covered long cylindrical non-isotropic dielectric lenses for targeted control of energy distribution
In this paper, a long column lens with a circular cross section made of two transversely non-isotropic dielectric parts covered by an isotropic plasma layer, is studied. The response of the mentioned


Dynamic spectral mapping of interstellar plasma lenses
Compact radio sources sometimes exhibit intervals of large, rapid changes in their flux-density, due to lensing by interstellar plasma crossing the line-of-sight. A novel survey program has made it
Extreme Scattering Events: insights into the interstellar medium on AU-scales
Several radio-wave scintillation phenomena exhibit properties which are difficult to accommodate within the standard propagation model based on distributed Kolmogorov turbulence in the ionised ISM;
Two families of astrophysical diverging lens models
In the standard gravitational lensing scenario, rays from a background source are bent in the direction of a foreground lensing mass distribution. Diverging lens behaviour produces deflections in the
Folded Fields as the Source of Extreme Radio-Wave Scattering in the Galactic Center
A strong case has been made that radio waves from sources within about half a degree of the Galactic center undergo extreme diffractive scattering. However, problems arise when standard
Real-time detection of an extreme scattering event: Constraints on Galactic plasma lenses
Modeling of the radio data demonstrates that the lensing structure is a density enhancement and the lens is diverging, ruling out one of two competing physical models of ESEs.
Extreme Scattering Events and Galactic Dark Matter
"Extreme scattering events" (ESEs) are attributed to radio wave refraction by a cloud of free electrons crossing the line of sight. We present a new model in which these electrons form the
Radio caustics from localized interstellar medium plasma structures
In a study of, 36 extragalactic radio sources observed over 7 years with the Green Bank interferometer at 2.7 GHz and 8.1 GHz, Fiedler et al.1 have detected unusual variations in the light curves of
Interpretation of Extreme Scattering Events
Extreme Scattering Events are sometimes manifest in the light-curves of compact radio-quasars at frequencies of a few GHz. These events are not understood. The model which appears to offer the best

We present the geometrical optics for refraction of a distant background radio source by an interstellar plasma lens, with specific application to a lens with a Gaussian profile of free-electron
Extreme scattering events caused by compact structures in the interstellar medium
Daily flux density measurements of 36 extragalactic radio sources over a seven year period reveal several unusual minima in the light curves that do not follow typical source variations. The
