Description
We investigate the far infrared (IR) spectrum of NGC 1266, a S0 galaxy
that contains a massive reservoir of highly excited molecular gas. Using
the Herschel Fourier Transform Spectrometer, we detect the
12CO ladder up to J = (13-12), [C I] and [N II] lines, and
also strong water lines more characteristic of UltraLuminous IR Galaxies
(ULIRGs). The 12CO line emission is modeled with a
combination of a low-velocity C-shock and a photodissociation region.
Shocks are required to produce the H2O and most of the high-J
CO emission. Despite having an IR luminosity 30 times less than a
typical ULIRG, the spectral characteristics and physical conditions of
the interstellar medium of NGC 1266 closely resemble those of ULIRGs,
which often harbor strong shocks and large-scale outflows.
