Attenuation

Synthesizer provides a number of different dust attenuation laws that can be used to attenuate the emission from a galaxy or galaxy component. These models can be attached to an EmissionModel (see the emisison model docs) or used directly with an Sed object (see the SED docs).

In addition to these attenuation laws, we also provide two Intergalactic Medium (IGM) absorption models, which can be used to attenuate the flux from a galaxy or galaxy component.

In the linked sections below we detail the basic functionality and usage of both attenuation laws and IGM absorption models.
