Description
We solve the transport equations of cosmic rays inside a molecular cloud assuming an arbitrary energy and space dependent diffusion coefficient. Cosmic rays penetrating the cloud produce gamma-ray emission through pp collisions with the ambient gas. For small diffusion coefficients inside the cloud we expect the gamma-ray spectrum from the cloud to be harder than the Galactic diffuse emission spectrum, mainly due to the slower penetration of the low energy particles towards the core of the cloud. Moreover we study the influence of the gas density profile on thegamma-ray emission. Finally we present predictions for present and future telescopes to observe gamma-ray emission from molecular clouds and from their dense cores.
