Modern view of the warm ionized medium
A. S. Hill, R. J. Reynolds, L. M. Haffner +2
We review the observational evidence that the warm ionized medium (WIM) is a major and physically distinct component of the Galactic interstellar medium. Although up to ~20% of the…
Early Results from the Wisconsin H-Alpha Mapper Southern Sky Survey
L. M. Haffner, R. J. Reynolds, G. J. Madsen +6
After a successful eleven-year campaign at Kitt Peak, we moved the Wisconsin H-Alpha Mapper (WHAM) to Cerro Tololo in early 2009. Here we present some of the early data after a few…
The warm ionized medium in spiral galaxies
L. M. Haffner, R. -J. Dettmar, J. E. Beckman +6
This article reviews observations and models of the diffuse ionized gas that permeates the disk and halo of our Galaxy and others. It was inspired by a series of invited talks pres…
Ionization of Infalling Gas
L. M. Haffner, A. K. Duncan, S. M. Hoffman +3
H-alpha emission from neutral halo clouds probes the radiation and hydrodynamic conditions in the halo. Armed with such measurements, we can explore how radiation escapes from the…
Dynamical Zodiacal Cloud Models Constrained by High Resolution Spectroscopy of the Zodiacal Light (Icarus, in press)
Sergei I. Ipatov, Alexander S. Kutyrev, Greg J. Madsen +3
The simulated Doppler shifts of the solar Mg I Fraunhofer line produced by scattering on the solar light by asteroidal, cometary, and trans-Neptunian dust particles are compared wi…
A Multiwavelength Optical Emission Line Survey of Warm Ionized Gas in the Galaxy
G. J. Madsen, R. J. Reynolds, L. M. Haffner
We report on observations of several optical emission lines toward a variety of newly revealed faint, large-scale Halpha-emitting regions in the Galaxy. The lines include [NII] 658…
