First Detection of PAHs and Warm Molecular Hydrogen in Tidal Dwarf Galaxies
S. J. U. Higdon, J. L. Higdon, J. Marshall
We observed two faint tidal dwarf galaxies (TDGs), NGC 5291N and NGC 5291 S with the Infrared Spectrograph on the Spitzer Space Telescope. We detect strong polycyclic aromatic hydr…
Detection of the Buried AGN in NGC 6240 with the Infrared Spectrograph on The Spitzer Space Telescope
L. Armus, J. Bernard-Salas, H. W. W. Spoon +10
We present mid-infrared spectra of the nearby, Ultraluminous Infrared Galaxy NGC 6240 taken with the IRS on Spitzer. The spectrum of NGC 6240 is dominated by strong fine-structure…
The Detection of Silicate Emission from Quasars at 10 and 18 Microns
Lei Hao, H. W. W. Spoon, G. C. Sloan +8
We report the spectroscopic detection of silicate emission at 10 and 18 microns in five PG quasars, the first detection of these two features in galaxies outside the Local Group. T…
