The future of high-resolution UV spectroscopy: Science with a UV Échelle spectrograph on the Habitable Worlds Observatory, or a dedicated mission
Annalisa De Cia, David Cont, Kevin Heng +39
High-resolution UV spectroscopy serves a diversity of science cases, from small bodies to planets, stars, and galaxies, but is currently limited to the Hubble Space Telescope and b…
The densities in diffuse and translucent molecular clouds: estimates from observations of C and from 3-dimensional extinction maps
David A. Neufeld, Daniel E. Welty, Alexei V. Ivlev +7
Newly-computed collisional rate coefficients for the excitation of C in collisions with H, presented recently by Najar and Kalugina (2020), are significantly larger than th…
HD 62542: Probing the Bare, Dense Core of a Translucent Interstellar Cloud
Daniel E. Welty, Paule Sonnentrucker, Theodore P. Snow +1
We discuss the interstellar absorption from many atomic and molecular species seen in high-resolution /STIS UV and high-S/N optical spectra of the moderately reddened B3-5~V s…
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…
Far to near UV spectroscopy of the interstellar medium at very high resolution and very high signal-to-noise ratio
Cecile Gry, Edward B. Jenkins, Patrick Boissé +4
A comprehensive study of interstellar medium phases and the nature of their boundaries or connections requires comparing abundances and velocity profiles from tracers of the differ…
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)]…
