Variations of Interstellar Gas-to-Dust Ratios at High Galactic Latitudes
J. Michael Shull, Georgia V. Panopoulou
Interstellar dust at high Galactic latitudes can influence astronomical foreground subtraction, produce diffuse scattered light, and soften the ultraviolet spectra of quasars. In a…
The Spatial and Emission Properties of the Large [O III] Emission Nebula Near M31
Robert A. Fesen, Stefan Kimeswenger, J. Michael Shull +8
Drechsler et al. (2023) reported the unexpected discovery of a 1.5 degree long [O III] emission nebula 1.2 degrees southeast of the M31 nucleus. Here we present additional images o…
Interstellar Bow Shocks around Fast Stars Passing through the Local Interstellar Medium
J. Michael Shull, S. R. Kulkarni
Bow-shocks are produced in the local interstellar medium by the passage of fast stars from the Galactic thin-disk and thick-disk populations with velocities 40-80 km/s. St…
Two-photon production in low-velocity shocks
S. R. Kulkarni, J. Michael Shull
The Galactic interstellar medium abounds in low-velocity shocks with velocities less than, say, about 70 km/s. Some are descendants of higher velocity shocks, while others start of…
The Distribution of Metallicities in the Local Galactic Interstellar Medium
Adam M. Ritchey, Edward B. Jenkins, J. Michael Shull +3
In this investigation, we present an analysis of the metallicity distribution that pertains to neutral gas in the local Galactic interstellar medium (ISM). We derive relative ISM m…
Mass, Morphing, Metallicities: The Evolution of Infalling High Velocity Clouds
F. Heitsch, A. Marchal, M. -A. Miville-Deschênes +2
We revisit the reliability of metallicity estimates of high velocity clouds with the help of hydrodynamical simulations. We quantify the effect of accretion and viewing angle on me…
