High brightness-temperature radiation is observed in various astrophysical sources: active galactic nuclei, pulsars, interstellar masers, and flaring stars; the discovery of fast radio bursts renewed interest in the nonlinear interaction of intense radiation with plasma. In astronomical systems, the radiation frequency is typically well above the plasma frequency and its spectrum is broad, so nonlinear processes differ considerably from those typically studied in laboratory plasma.

Stimulated Compton scattering of electromagnetic waves in plasma
The so−called stimulated Compton effect is investigated on a one−and−two−halves−dimensional electromagnetic plasma model. This effect results in a parametric instability in which an electromagnetic
Physical processes in eclipsing pulsars: Eclipse mechanisms and diagnostics
We investigate how the radio emission of a pulsar interacts with plasma derived from a stellar companion. Various physical mechanisms that can cause radio pulse eclipse are discussed, and predictions
Persistence of Precursor Waves in Two-dimensional Relativistic Shocks
We investigated the efficiency of coherent upstream large-amplitude electromagnetic wave emission via synchrotron maser instability in relativistic magnetized shocks using two-dimensional
Physics of Interpulse Emission in Radio Pulsars
The magnetized induced Compton scattering off the particles of the ultrarelativistic electron-positron plasma of pulsar is considered. The main attention is paid to the transverse regime of the
Interpretation of the low-frequency peculiarities in the radio profile structure of the Crab pulsar
The theory of magnetized induced scattering off relativistic gyrating particles is developed. It is directly applicable to the magnetosphere of a pulsar, in which case the particles acquire gyration
On the Structure of Relativistic Collisionless Shocks in Electron-Ion Plasmas
Relativistic collisionless shocks in electron-ion plasmas are thought to occur in the afterglow phase of gamma-ray bursts (GRBs) and in other environments where relativistic flows interact with the
Formation of the radio profile components of the Crab pulsar
The induced Compton scattering of radio emission off the particles of the ultrarelativistic electron–positron plasma in the open field line tube of a pulsar is considered. We examine the scattering
Anisotropic induced Compton scattering - Constraints on models of active galactic nuclei
Induced Compton scattering can cause strong spectral distortion when the Thomson scattering optical depth τT exceeds 5 × 10^9 K/T, where T is the brightness temperature. Observations of intraday

This is the second in the series of papers aiming to study interaction of the electromagnetic precursor waves from relativistic shocks with the upstream flow. Here, I consider the induced
Self-modulation of fast radio bursts
Fast Radio Bursts (FRBs) are extreme astrophysical phenomena entering the realm of non-linear optics, a field developed in laser physics. A classical non-linear effect is self-modulation. We examine
