The Central 300 pc of the Galaxy Probed by Infrared Spectra of H and CO: III. Locations of Sgr B2 and Star
Takeshi Oka, T. R. Geballe
Using a simple relation between the radial expansion velocity of diffuse gas in the Central Molecular Zone (CMZ) of the Galaxy and its distance from Sgr A we estimate the ph…
The Central 300 pc of the Galaxy probed by infrared spectra of H3+ and CO: II. Expansion and morphology of the warm diffuse gas
Takeshi Oka, T. R. Geballe
Velocity profiles of a line of H at 3.7 m produced in warm diffuse gas have been observed toward 18 stars in the Central Molecular Zone (CMZ) of the Galaxy. Their longitud…
The Central 300 pc of the Galaxy probed by infrared spectra of H and CO: part I. Predominance of warm and diffuse gas and high H ionization rate
Takeshi Oka, T. R. Geballe, Miwa Goto +4
The molecular gas in the Central Molecular Zone (CMZ) of the Galaxy has been studied using infrared absorption spectra of H lines at 3.5-4.0 m and CO lines near 2.34 m.…
Background Infrared Sources for Studying the Galactic Center's Interstellar Gas
T. R. Geballe, E. Lambrides, B. Schlegelmilch +5
We briefy describe the results of a K-band spectroscopic survey of over 500 highly reddened point-like objects on sightlines toward the Central Molecular Zone (CMZ) of the Galaxy.…
Constraining the size of the carrier of the 5797.1 diffuse interstellar band
Jane Huang, Takeshi Oka
The diffuse interstellar band (DIB) at 5797.1 Å is simulated based on three premises: (1) The carrier of the DIB is polar as concluded by T. Oka et al. from the anomalous spectrum…
Infrared H3+ and CO Studies of the Galactic Core: GCIRS 3 and GCIRS 1W
Miwa Goto, T. R. Geballe, Nick Indriolo +4
We have obtained improved spectra of key fundamental band lines of H3+, R(1,1)l, R(3,3)l, and R(2,2)l, and ro-vibrational transitions of CO on sightlines toward the luminous infrar…
