Scientific paper
Herschel was successfully launched on 14 May 2009. It is the first large aperture space infrared observatory carrying a 3.5 metre diameter passively cooled Cassegrain telescope and and three science instruments, PACS, SPIRE, and HIFI, whose focal plane units are housed in a superfluid helium cryostat.
It builds on previous infrared space missions and submillimetre ground observatories, bridging the remaining spectral gap by performing imaging photometry and spectroscopy in the far infrared and submillimetre part of the spectrum, covering approximately the 55-672 micron range and offering unique observing opportunities for a wide variety of observing programmes.
I will summarise the various activities conducted since launch, and provide the current status and demonstrated in-flight performance. This will be illustrated by some of the observing highlights to date. Current observations performed range from water in a comet and the first far-infrared detection of a TNO in our solar system, star formation in our galaxy, nearby galaxies, line emission in start-burst galaxies, to resolving the cosmic infrared background into its constituent galaxies to a degree never before achieved around the peak of its SED, and includes the detection of the most distant known quasar (z=6.42).
I will also describe the AO which will be released just before the meeting, its scope, associated documentation, and tools.
