Description Composite supernova remnants present us with a unique opportunity for detecting and characterizing supernova ejecta and dust as it is being illuminated by the central pulsar wind nebula. Kes 75 is a Galactic remnant consisting of a pulsar wind nebula and a partial thermal shell. It has been observed at radio, infrared, and X-ray wavelengths, but the nature of the observed emission and the progenitor star remains unknown. High absorption towards the remnant has prohibited any optical searches for supernova ejecta and has made the results from X-ray observations inconclusive. However, the 70 micron image from the Herschel Hi-GAL key project revealed emission around the pulsar wind nebula that most likely originates from the interaction of the nebula with supernova ejecta and dust. Observations with Herschel are currently the only means of detecting this ejecta and constraining the total mass of swept up gas and dust in Kes 75. We therefore propose Herschel PACS imaging and spectroscopy of the pulsar wind nebula and shell in Kes 75 in order to determine the remnant.s properties and understand the nature of the supernova progenitor.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
