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…
A New Spin on Galactic Dust
Angelica de Oliveira-Costa, Max Tegmark, Douglas P. Finkbeiner +9
We present a new puzzle involving Galactic microwave emission and attempt to resolve it. On one hand, a cross-correlation analysis of the WHAM H-alpha map with the Tenerife 10 and…
Galactic contamination in the QMAP experiment
Angelica de Oliveira-Costa, Max Tegmark, Mark J. Devlin +6
We quantify the level of foreground contamination in the QMAP Cosmic Microwave Background (CMB) data with two objectives: (a) measuring the level to which the QMAP power spectrum m…
