The Wisconsin H-Alpha Mapper Northern Sky Survey
L. M. Haffner, R. J. Reynolds, S. L. Tufte +3
The Wisconsin H-Alpha Mapper (WHAM) has surveyed the distribution and kinematics of ionized gas in the Galaxy above declination -30 degrees. The WHAM Northern Sky Survey (WHAM-NSS)…
WHAM Observations of H-alpha from High-Velocity Clouds: Are They Galactic or Extragalactic?
S. L. Tufte, J. D. Wilson, G. J. Madsen +2
It has been suggested that high velocity clouds may be distributed throughout the Local Group and are therefore not in general associated with the Milky Way galaxy. With the aim of…
Interstellar H-Alpha Line Profiles toward HD 93521 and the Lockman Window
N. R. Hausen, R. J. Reynolds, L. M. Haffner +1
We have used the Wisconsin H-Alpha Mapper (WHAM) facility to measure the interstellar H-Alpha emission toward the high Galactic latitude O star HD 93521 (l = 183.1, b = +62.2). Thr…
Observations of the Extended Distribution of Ionized Hydrogen in the Plane of M31
G. J. Madsen, R. J. Reynolds, L. M. Haffner +2
We have used the Wisconsin H-Alpha Mapper (WHAM) to observe the spatially extended distribution of ionized hydrogen in M31 beyond the stellar disk. We obtained five sets of observa…
A Map of the Ionized Component of the Intermediate Velocity Cloud Complex K
L. M. Haffner, R. J. Reynolds, S. L. Tufte
The Wisconsin H-Alpha Mapper (WHAM) Northern Sky Survey is revealing that many intermediate-velocity (|v_LSR| <= 100 km/s) neutral clouds and complexes have an associated ionized c…
Detection of [N II] 5755 Emission from Low Density Ionized Interstellar Gas
R. J. Reynolds, N. C. Sterling, L. M. Haffner +1
The extremely faint, temperature sensitive ``auroral'' emission line [N II] 5755 has been detected from the low density ionized gas along the sight line toward l = 130.0, b = -7.5…
