Herschel observations of EXtra-Ordinary Sources: the present and future of spectral surveys with Herschel / HIFI

The HIFI instrument offers unprecedented sensitivity, as well as continuous spectral coverage across the gaps imposed by the atmosphere, opening up a largely unexplored wavelength regime to high - resolution... ▽ More We present initial results from the Herschel GT key program: Herschel observations of EXtra-Ordinary Sources (HEXOS) and outline the promise and potential of spectral surveys with Herschel / HIFI.

We detect C3 in absorption arising from the warm envelope surrounding the... ▽ More We present spectrally resolved observations of triatomic carbon (C3) in several ro - vibrational transitions between the vibrational ground state and the low - energy nu2 bending mode at frequencies between 1654 - 1897 GHz along the sight - lines to the submillimeter continuum sources W31C and W49N, using Herschel's HIFI instrument.

Abstract: We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (band 6b) and 1788.4 - 1906.8 GHz (band 7b) obtained using the HIFI instrument on board the Herschel Space Observatory.
