UKIRT Widefield Infrared Survey for Fe\(^+\)

The United Kingdom Infrared Telescope (UKIRT) Widefield Infrared Survey for Fe\(^+\) (UWIFE) is a 180 deg\(^2\) imaging survey of the first Galactic quadrant (7\(^{\circ}\) < l < 62\(^{\circ}\); |b| < 1.5\(^{\circ}\)) using a narrow-band filter centered on the [Fe II] 1.644 {\mu}m emission...

Description
Summary:The United Kingdom Infrared Telescope (UKIRT) Widefield Infrared Survey for Fe\(^+\) (UWIFE) is a 180 deg\(^2\) imaging survey of the first Galactic quadrant (7\(^{\circ}\) < l < 62\(^{\circ}\); |b| < 1.5\(^{\circ}\)) using a narrow-band filter centered on the [Fe II] 1.644 {\mu}m emission line. The [Fe II] 1.644 {\mu}m emission is a good tracer of dense, shock-excited gas, and the survey will probe violent environments around stars: star-forming regions, evolved stars, and supernova remnants, among others. The UWIFE survey is designed to complement the existing UKIRT Widefield Infrared Survey for H2 (UWISH2; Froebrich et al. 2011). The survey will also complement existing broad-band surveys. The observed images have a nominal 5{\sigma} detection limit of 18.7 mag for point sources, with the median seeing of 0.83". For extended sources, we estimate surface brightness limit of 8.1 x 10\(^{-20}\) W m\(^{-2}\) arcsec\(^{-2}\) . In this paper, we present the overview and preliminary results of this survey.
