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.…
Observational Results of a Multi-Telescope Campaign in Search of Interstellar Urea [(NH)CO]
Anthony J. Remijan, Lewis E. Snyder, Brett A. McGuire +10
In this paper, we present the results of an observational search for gas phase urea [(NH)CO] observed towards the Sgr B2(N-LMH) region. We show data covering urea transitio…
Investigating the Cosmic-Ray Ionization Rate in the Galactic Diffuse Interstellar Medium through Observations of H3+
Nick Indriolo, Benjamin J. McCall
Observations of H3+ in the Galactic diffuse interstellar medium (ISM) have led to various surprising results, including the conclusion that the cosmic-ray ionization rate (zeta_2)…
On the Ortho:Para Ratio of H3+ in Diffuse Molecular Clouds
Kyle N. Crabtree, Nick Indriolo, Holger Kreckel +2
The excitation temperature T_01 derived from the relative intensities of the J = 0 (para) and J = 1 (ortho) rotational levels of H2 has been assumed to be an accurate measure of th…
Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
Scott D. Friedman, Donald G. York, Benjamin J. McCall +7
We establish correlations between equivalent widths of eight diffuse interstellar bands (DIBs), and examine their correlations with atomic hydrogen, molecular hydrogen, and EB-V .…
Investigating the Cosmic-Ray Ionization Rate Near the Supernova Remnant IC 443 Through H3+ Observations
Nick Indriolo, Geoffrey A. Blake, Miwa Goto +5
Observational and theoretical evidence suggests that high-energy Galactic cosmic rays are primarily accelerated by supernova remnants. If also true for low-energy cosmic rays, the…
