High-Resolution Imaging of Molecular Line Emission from High-Redshift QSOs
starburst evolution radio lines
2014/12/26
We present moderate- (1'') and high-resolution (02) observations of the CO (2–1) emission at 43 GHz and radio continuum emission at 1.47 GHz from the z = 4.7 QSO BRI 1202-0725 and the z = 4.4 QSO BRI ...
High-resolution Imaging of Dust Shells Using Keck aperture Masking and the IOTA Interferometer
given current calibration software limitations
2014/12/24
We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array (IOTA) to image the circumstellar environments of evolved stars with …20 m...
High-Resolution Imaging of Warm and Dense Molecular Gas in the Nuclear Region of the Luminous Infrared Galaxy NGC 6240
formation interaction,
2014/12/23
We present ~2'' resolution CO (3-2), HCO+(4-3), and 880 μm continuum images of the luminous infrared galaxy NGC 6240 obtained at the Submillimeter Array. We find that the spatially resolved CO (3-2), ...
THE SPITZER INFRARED NEARBY GALAXIES SURVEY: A HIGH-RESOLUTION SPECTROSCOPY ANTHOLOGYlinl
ISM nuclei
2014/12/22
High-resolution mid-infrared spectra are presented for 155 nuclear and extranuclear regions from the Spitzer Infrared Nearby Galaxies Survey (SINGS). The fluxes for nine atomic forbidden and three mol...
A high-resolution line survey of IRC +10216 with Herschel/HIFI *,** First results: Detection of warm silicon dicarbide (SiC)

2014/12/20
We present the first results of a high-spectral-resolution survey of the carbon-rich evolved star IRC+10216 that was carried out with the HIFI spectrometer onboard Herschel. This survey covers all HIF...
High-resolution Ultraviolet Spectroscopy of Gas in Galaxy Halos and Large-scale Structures
galaxy intergalactic medium
2014/12/9
This dissertation presents spectroscopic studies of gas in galaxy halos and large-scale structures through high-resolution quasar absorption lines. The broad goal of this effort is to learn how galaxi...
