High Spatial Resolution Kao Far-infrared Observations of the Central Regions of Infrared-bright Galaxies
We present new high spatial resolution Kuiper Airborne Observatory (KAO) 50 μm and/or 100 μm data for 11 infrared-bright galaxies. The sizes of the central far-infrared emitting regions in three of these galaxies, NGC 660, NGC 891, and M 83, agree with those of the central star formation complexes. The Sb galaxy NGC 7331, which does not have observed star formation in its bulge, has a flat-topp...
متن کاملHigh-resolution far-infrared spectroscopy at NSLS beamline U12IR
A Bruker model IFS 125HR Fourier transform interferometer has been installed and its performance tested using high-brightness, far-infrared synchrotron radiation. Results of absorption measurements for the rotational modes of water vapor demonstrate a nearly 10-fold improvement in signal-to-noise when compared with the instrument’s internal high-pressure Hg arc lamp source. 2008 Published by El...
متن کاملMeasurement of stratospheric HBr using high resolution far infrared spectroscopy
Far infrared spectral features of HBr have been observed in the stratospheric emission spectrum using a balloon borne high resolution Fourier transform spectrometer equipped with a high sensitivity detector specially designed for this purpose. The value of 1.6 + 0.6 parts per trillion in volume for the HBr mixing ratio has been retrieved, from the global-fit analysis of 12! spectra, in the 25 3...
متن کاملHigh Spatial Resolution Mid-infrared Observations of Three Seyfert Galaxies
Images at 12.5 lm of nuclei of three nearby Seyfert galaxies—NGC 1275, NGC 4151, and NGC 7469— have been obtained with the 10 m Keck Telescope. NGC 7469 is resolved and deconvolution delineates a structure (<0>04) 0>08, or less than 13 26 pc at a position angle of 135 . From a comparison with structure seen at millimeter wavelengths, this structure is interpreted as a disk aligned with the mole...
متن کاملHigh - Spatial - Resolution , near - Infrared Observations of Arp 220
High-spatial-resolution slit scans of the nucleus of Arp 220 are presented along with near-infrared photometry of the nuclear region. A single nucleus is found coincident with the strongest radio peak. The core is resolved to be on the order of 1" (370 pc) in diameter. The photometry of the central region shows a minimum near 3.7 ¡im which is inconsistent with the near-infrared source being a “...
