Point Sources from a Spitzer IRAC Survey of the Galactic Center
Solange V. Ramirez, Richard G. Arendt, Kris Sellgren +4
We have obtained Spitzer/IRAC observations of the central 2.0 x 1.4 degrees (~280 x 200 pc) of the Galaxy at 3.6-8.0 microns. A point source catalog of 1,065,565 objects is present…
New PAH mode at 16.4 microns
C. Moutou, L. Verstraete, A. Leger +2
The detection of a new 16.4 micron emission feature in the ISO-SWS spectra of NGC 7023, M17, and the Orion Bar is reported. Previous laboratory experiments measured a mode near thi…
ISO Mid-Infrared Spectra of Reflection Nebulae
K. I. Uchida, K. Sellgren, M. W. Werner +1
We present 5-15 micron imaging spectroscopy of the reflection nebulae vdB 17 (NGC 1333), vdB 59 (NGC 2068), vdB 101, vdB 111, vdB 133 and vdB 135, obtained with the infrared camera…
Upper limit on C60 and C60+ features in the ISO-SWS spectrum of the reflection nebula NGC 7023
C. Moutou, K. Sellgren, L. Verstraete +1
We present here the 7.0-8.7 micron spectrum of the bright reflection nebula NGC 7023. Our observations are made with the Short Wavelength Spectrometer (SWS) on the European satelli…
