Scintillation spectra of some pulsars have suggested the existence of ≲ AU scale density structures in the ionized interstellar medium, whose astrophysical correspondence is still a mystery. The detailed study of Brisken et al. suggested two possible morphologies for these structures: A parallel set of filaments or sheets (the ‘parallel stripes model’), or a filament broken up into denser knots (the ‘threaded beads model’). Here, we propose a straightforward test that can distinguish these… Expand

Faint scattering around pulsars: probing the interstellar medium on solar system size scales
We have made high-resolution, high-sensitivity dynamic spectra of a sample of strong pulsars at 430 MHz with the Arecibo radio telescope. For four pulsars we find faint but sharply delineatedExpand
Predicting pulsar scintillation from refractive plasma sheets
The dynamic and secondary spectra of many pulsars show evidence for long-lived, aligned images of the pulsar that are stationary on a thin scattering sheet. One explanation for this phenomenonExpand
Pulsar lensing geometry
Our analysis of archival VLBI data of PSR 0834+06 revealed that its scintillation properties can be precisely modelled using the inclined sheet model (Pen & Levin 2014), resulting in two distinctExpand
Deflection of Pulsar Signal Reveals Compact Structures in the Galaxy
We have detected a strong deflection of radio waves from the pulsar PSR B0834+06 in scintillation observations. Interference between the undeflected pulsar image and deflected subimages allowsExpand
Scintillation Arcs in Pulsar B0450–18
We report on Green Bank Telescope observations of interstellar scintillation from the pulsar B0450−18 at 340 and 825 MHz, revealing prominent arcs in the secondary spectra at both frequencies. TheExpand

Gravitational microlensing has become a mature technique for discovering small gravitational lenses in the Universe that are otherwise beyond our detection limits. Similarly, plasma microlensingExpand
100 μas Resolution VLBI Imaging of Anisotropic Interstellar Scattering Toward Pulsar B0834+06
We have invented a novel technique to measure the radio image of a pulsar scattered by the interstellar plasma with 0.1 mas resolution. We extend the 'secondary spectrum' analysis of parabolic arcsExpand
Extreme radio-wave scattering associated with hot stars
We use data on extreme radio scintillation to demonstrate that this phenomenon is associated with hot stars in the solar neighbourhood. The ionized gas responsible for the scattering is found atExpand
Extreme scattering events towards two young pulsars
We have measured the scintillation properties of 151 young, energetic pulsars with the Parkes radio telescope and have identified two extreme scattering events (ESEs). Towards PSR J1057-5226 weExpand
Theory of Parabolic Arcs in Interstellar Scintillation Spectra
Our theory relates the secondary spectrum, the 2D power spectrum of the radio dynamic spectrum, to the scattered pulsar image in a thin scattering screen geometry. Recently discovered parabolic arcsExpand
