Microwave Interstellar Medium Emission Observed by the Wilkinson Microwave Anisotropy Probe (2004, methodology): “Free-Free Although warm ionized gas is well traced by H emission in three recent surveys (VTSS, Dennison et al. 1998; SHASSA, Gaustad et al. 2001; WHAM, Haffner et al. 2003) as presented by Finkbeiner (2003) and corrected for dust using the Schlegel et al. (1998; hereafter SFD98) dust map, one must ”
The H i Distribution of the Milky Way (2009, methodology): “The WIM shows in the Wisconsin HAlpha Mapper survey (Haffner et al. 2003) some distinct sources, but these are also superposed on a diffuse background.”
Gaseous Galaxy Halos (2012, background): “In addition, the WIM layer of our Galaxy detected in Hα shows a net inflow as one examines the regions toward both poles (Haffner et al., 2003; Putman et al., 2009b).”
The Vertical Structure of Warm Ionised Gas in the Milky Way (2008, background): “This is more than order of magnitude smaller than that observed (Reynolds 1991b; Peterson & Webber 2002; Haffner et al. 2003), suggesting that there is substantial clumping of the WIM at large distances from the Galactic plane, not included in NE2001 (see also discussion by Reynolds 1991b, 1997).”
NINE-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP) OBSERVATIONS: FINAL MAPS AND RESULTS (2012, methodology): “The Finkbeiner map is a composite of the Virginia Tech Spectral line Survey (Dennison et al. 1998), the Southern H-alpha Sky Survey Atlas (Gaustad et al. 2001), and the Wisconsin H alpha Mapper survey (Haffner et al. 2003).”
A Nearby Repeating Fast Radio Burst in the Direction of M81 (2021, methodology): “Finally, we searched the FRB field of view in the Wisconsin HαMapper Northern Sky Survey (WHAM; Haffner et al. 2003) for the presence of any extended and diffuse Hα excess clump but did not find any.”
Density Fluctuations in MHD Turbulence: Spectra, Intermittency, and Topology (2006, background): “Themain goal of another observational project, theWisconsinH-AlphaMapper (WHAM), is to provide a survey of H emission from the ISM over the entire northern sky (Haffner et al. 2003; Hill et al. 2005).”
The warm ionized medium in spiral galaxies (2009, background): “VIEW FROM THE INSIDE: DIVING INTO THE PHYSICS OF THE WARM IONIZED MEDIUM IN OUR GALAXY”
Extended Anomalous Foreground Emission in the WMAP Three-Year Data (2007, methodology): “Our template for this foreground is the Hα map, assembled from the VTSS (Dennison et al. 1998), SHASSA (Gaustad et al. 2001), and WHAM (Haffner et al. 2003) surveys by Finkbeiner (2003).”
The AAO/UKST SuperCOSMOS Hα survey (2005, methodology): “Fortunately, one modern Hα survey, WHAM (e.g. Haffner et al. 2003), offers very good velocity resolution (∼12 km/s) and is able to separate the atmospheric emission from the Galactic emission and measure the intensity.”
A NEW ELECTRON-DENSITY MODEL FOR ESTIMATION OF PULSAR AND FRB DISTANCES (2016, background): “6 For a catalog of currently known FRBs, see http://www.astronomy.swin. edu.au/pulsar/frbcat/ and Petroff et al. (2016). largely originates in the more widely distributed “warm ionized medium” (WIM), which can be investigated using wide-field Hα observations (e.g., Haffner et al. 2003).”
EXTENDING THE BIG POWER LAW IN THE SKY WITH TURBULENCE SPECTRA FROM WISCONSIN Hα MAPPER DATA (2009, background): “The WHAM Northern Sky Survey (WHAM-NSS) has an angular resolution of 1◦ and provides the first absolutely calibrated, kinematically resolved map of the Hα emission from the warm ionized medium (WIM) within ±100 km s−1 of the local standard of rest (Haffner et al. 2003).”
The Bubbling Galactic Disk (2006, methodology): “Large bubbles (greater than 100 in diameter) have also been identified in theH i SouthernGalactic Plane Survey (McClure-Griffiths et al. 2002) and with theWisconsin H Mapper (WHAM;Haffner et al. 2003).”
Radio observational constraints on Galactic 3D-emission models (2007, methodology): “…et al. (2003) have constructed an extinction corrected free-free emission template for about 95% of the sky based on Hα surveys of the northern sky (Haffner et al. 2003) and of the southern sky (Gaustad et al. 2001) by using dust emission data (Schlegel et al. 1998) to calculate the extinction…”
