The Herschel key project to study the warm and dense interstellar medium

Observations using the HIFI and PACS instruments aboard the Herschel satellite provide a unique way to study the chemical inventory and the energy balance in dense interstellar clouds heated by shocks and UV radiation.

Here, you find a detailed description of the project including scientific and technical aspects.

Scientific summary
An explanation of the scientific questions we want to answer in the key project.
A list of all co-investigators that you may want to contact in case of questions.
Photon-dominated regions (PDRs), i.e. dense clouds heated by UV radiation, provide one focus of the key project.
Shock regions
Supernova-shocks, dynamically heating the interstellar medium, provide the second focus of the key project.
Using Herschel/HIFI
Only the new technical capabilities offered by the Herschel Space Observatory allow to answer our questions.
Observing strategy
A sophisticated observational setup is essential to get the required data in the available observing time.
Observational setup
The detailed list of lines and objects to be observed.
