Nonthermal Spectral Models for ISIS


This module provides spectral models for synchrotron radiation, inverse Compton scattering, nonthermal bremsstrahlung and neutral-pion decay produced by a homogeneous emitting region. The underlying momentum distribution of relativistic particles may be user-defined or may be chosen from a number of simple analytic particle distribution functions provided by the module.

The module also provides functions to compute additional useful quantities including the number density and energy density of relativistic particles.


The users' manual is available in several formats:

Physical assumptions and computational details are discussed in Houck and Allen (2006).
