Abstract:
A sample of 379 extragalactic sources is presented that has
mid-infrared, high-resolution spectroscopy from the Spitzer Infrared
Spectrograph (IRS) and also spectroscopy of the [CII]158µm line
from the Herschel Photodetector Array Camera and Spectrometer (PACS).
The emission line profiles of [NeII]12.81µm, [NeIII]15.55µm, and
[CII]158µm are presented, and intrinsic line widths are determined
(full width half maximum of Gaussian profiles after instrumental
correction). All line profiles, together with overlays comparing the
positions of PACS and IRS observations, are made available in the
Cornell Atlas of Spitzer IRS Sources (CASSIS). Sources are classified
from active galactic nucleus (AGN) to starburst based on equivalent
widths of the 6.2µm polycyclic aromatic hydrocarbon feature. It is
found that intrinsic line widths do not change among classifications
for [CII], with median widths of 207km/s for AGNs, 248km/s for
composites, and 233km/s for starbursts. The [NeII] line widths also do
not change with classification, but [NeIII] lines are progressively
broader from starburst to AGN. A few objects with unusually broad
lines or unusual redshift differences in any feature are identified.
