Outflowing Diffuse Gas in the Active Galactic Nucleus of NGC 1068
T. R. Geballe, R. E. Mason, T. Oka
Spectra of the archetypal Type II Seyfert galaxy NGC 1068 in a narrow wavelength interval near 3.7 microns have revealed a weak absorption feature due to two lines of the molecular…
Absorption Line Survey of H3+ toward the Galactic Center Sources III. Extent of the Warm and Diffuse Clouds
M. Goto, T. Usuda, T. R. Geballe +4
We present follow-up observations to those of Geballe & Oka (2010), who found high column densities of H3+ ~100 pc off of the Galactic center (GC) on the lines of sight to 2MASS J1…
Two New and Remarkable Sightlines through the Galactic Center's Molecular Gas
T. R. Geballe, T. Oka
Until now the known sources in the Galactic center with sufficiently smooth spectra and of sufficient brightness to be suitable for high resolution infrared absorption spectroscopy…
H3+ in Diffuse Interstellar Clouds: a Tracer for the Cosmic-Ray Ionization Rate
Nick Indriolo, Thomas R. Geballe, Takeshi Oka +1
Using high resolution infrared spectroscopy we have surveyed twenty sightlines for H3+ absorption. H3+ is detected in eight diffuse cloud sightlines with column densities varying f…
Absorption Line Survey of H3+ toward the Galactic Center Sources I. GCS 3-2 and GC IRS3
M. Goto, B. J. McCall, T. R. Geballe +4
We present high-resolution (R = 20000) spectroscopy of H3+ absorption toward the luminous Galactic center sources GCS 3-2 and GC IRS 3. With the efficient wavelength coverage affor…
Observations of H3+ in the Diffuse Interstellar Medium
B. J. McCall, K. H. Hinkle, T. R. Geballe +6
Surprisingly large column densities of H3+ have been detected using infrared absorption spectroscopy in seven diffuse cloud sightlines (Cygnus OB2 12, Cygnus OB2 5, HD 183143, HD 2…
