The Astrophysical JournalWe use the CN/CO intensity ratio to obtain the dense gas fraction, f _dense , for a sample of 16 ultraluminous and luminous infrared (IR) galaxies and compare f _dense with a suite of global galaxy properties.

The First Exploration of the Correlations Between WISE 12 μm and CO Emission in Early-type Galaxies
The Astrophysical JournalWe present the analysis of a comprehensive sample of 352 early-type galaxies using public data, to investigate the correlations between CO luminosities and mid-infrared luminosities observed by Wide-field Infrared Survey Explorer.

SMILES: A Prototype JWST Multiband Mid-infrared Survey
The Astrophysical JournalThe Mid-Infrared Instrument (MIRI) for JWST is supplied with a suite of imaging band-pass filters optimized for full spectral coverage in eight intermediate-width bands from 5 to 26 μ m and a narrower one at 11.3 μ m.

Far-Infrared Surveys of Galaxy Evolution [PDF]
Annual Review of Astronomy and Astrophysics, 2014 Roughly half of the radiation from evolving galaxies in the early Universe reaches us in the far-infrared and submillimeter wavelength ranges. Recent major advances in observing capabilities, in particular the launch of the Herschel Space Observatory in 2009, have dramatically enhanced our ability to use this information in the context of ...

, 2000 The mid infrared spectra of the starbursts show the 9.7$ m$ silicate absorption feature and strong mid infrared emission bands centered at 6.2, 7.7, and 11.3 $ $m. Illustrative models of the {\it active} galaxies are presented: As the starbursts are most likely confined to the central region of the galaxy the radiative transfer in the nucleus is ...
