The Apache Point Observatory Catalog of Optical Diffuse Interstellar Bands
Haoyu Fan, L. M. Hobbs, Julie A. Dahlstrom +7
Aiming for a new and more comprehensive DIB catalog between 4,000 and 9,000Å, we revisited the Atlas Catalog based on the observations of HD 183143 and HD 204827 (Hobbs et al. 2008…
The Behavior of Selected Diffuse Interstellar Bands with Molecular Fraction in Diffuse Atomic and Molecular Clouds
Haoyu Fan, Daniel E. Welty, Donald G. York +10
We study the behavior of eight diffuse interstellar bands (DIBs) in different interstellar environments, as characterized by the fraction of hydrogen in molecular form [(H)]…
Diffuse Atomic and Molecular Gas in the Interstellar Medium of M82 toward SN 2014J
Adam M. Ritchey, Daniel E. Welty, Julie A. Dahlstrom +1
We present a comprehensive analysis of interstellar absorption lines seen in moderately-high resolution, high signal-to-noise ratio optical spectra of SN 2014J in M82. Our observat…
Diffuse Interstellar Bands vs. Known Atomic and Molecular Species in the Interstellar Medium of M82 toward SN 2014J
Daniel E. Welty, Adam M. Ritchey, Julie A. Dahlstrom +1
We discuss the absorption due to various constituents of the interstellar medium of M82 seen in moderately high resolution, high signal-to-noise ratio optical spectra of SN 2014J.…
Anomalous Diffuse Interstellar Bands in the Spectrum of Herschel 36. I. Observations of Rotationally Excited CH and CH+ Absorption and Strong, Extended Redward Wings on Several DIBs
Julie Dahlstrom, Donald G. York, Daniel E. Welty +9
Anomalously broad diffuse interstellar bands (DIBs) at 5780.5, 5797.1, 6196.0, and 6613.6 A are found in absorption along the line of sight to Herschel 36, the star illuminating th…
Anomalous Diffuse Interstellar Bands in the Spectrum of Herschel 36. II. Analysis of Radiatively Excited CH+, CH, and DIBs
Takeshi Oka, Daniel E. Welty, Sean Johnson +3
Absorption spectra toward Herschel 36 for the A^1Pi <-- X^1Sigma transitions of CH+ in the J=1 excited rotational level and the A^2Delta <-- X^2Pi transition of CH in the J=3/2 exc…
Galaxies with Background QSOs, I: A Search for Strong Galactic H-alpha Lines
Donald G. York, Lorrie A. Straka, Michael Bishof +12
A search for emission lines in foreground galaxies in quasar spectra (z(gal) < z(QSO)) of the Sloan Digital Sky Survey (SDSS) data release 5 (DR5) reveals 23 examples of quasars sh…
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 .…
