$\gamma$-ray flux from Dark Matter Annihilation in Galactic Caustics

, 2005
In the frame of indirect dark matter searches we investigate the flux of high-energy $\gamma$-ray photons produced by annihilation of dark matter in caustics within our Galaxy under the hypothesis that the bulk of dark matter is composed of the lightest ...

Numerical modelling of caustics of solid state disk lasers

MATEC Web of Conferences, 2018
This paper concerns mathematical modelling of caustics of solid state laser YAG type with the disk active medium. The heat source model is developed on the basis of interpolation algorithms using geostatistical kriging method.

Esophageal Mucosal Injuries From Drugs, Radiation, and Caustic Agents [PDF]

The Korean Journal of Helicobacter and Upper Gastrointestinal Research
Various factors can lead to esophageal mucosal injury. A thorough patient history is crucial to accurately diagnose esophageal injuries caused by drugs, radiation, and caustic agents.

The discriminant of quasi m-boundary singularities

Demonstratio Mathematica
We describe the discriminant of deformations of simple quasi m-boundary equivalence classes for m≥2m\ge 2. All quasi simple mm-boundary classes are right equivalent to Arnold’s singularities (ADE).

Caustics, Cold Flows, and Annual Modulation

Advances in Astronomy, 2011
We discuss the formation of dark matter caustics, and their possible detection by future dark matter experiments. The annual modulation expected in the recoil rate measured by a dark matter detector is discussed.

THE NONLINEAR CAUSTIC

Tamkang Journal of Mathematics, 1991
In this paper the boundary layer at the nonlinear caustic is discussed and a nonlinear Airy equation is,obtained by adapting techniques from linear theory. It is shown that the incident beam undergoes a phase shift by an amount of $\pi/2$ as it passes through the caustic and becomes the outgoing beam.

The internal caustic structure of illuminated liquid droplets [PDF]

The internal electric field of an illuminated liquid droplet is studied in detail using both wave theory and ray theory. The internal field obtains its maximum values on the caustics within the droplet.

Branched flow and caustics in nonlinear waves

New Journal of Physics, 2019
Rogue waves, i.e. high amplitude fluctuations in random wave fields, have been studied in several contexts, ranging from optics via acoustics to the propagation of ocean waves.

The binary gravitational lens and its extreme cases [PDF]

, 1999
The transition of the binary gravitational lens from the equal mass case to small (planetary) mass ratios q is studied. It is shown how the limit of a (pure shear) Chang-Refsdal lens is approached, under what conditions the Chang-Refsdal approximation is
