The discovery of new Wolf–Rayet (WR) stars in our Galaxy via large-scale narrowband optical surveys has been severely limited by dust extinction. Recent improvements in infrared technology have made narrowband–broadband imaging surveys viable again. We report a new J, K, and narrowband imaging survey of 300 deg2 of the plane of the Galaxy, spanning 150 degrees in Galactic longitude and reaching 1 degree above and below the Galactic plane. The survey has a useful limiting magnitude of K = 15… 

A NEAR-INFRARED SURVEY OF THE INNER GALACTIC PLANE FOR WOLF-RAYET STARS. II. GOING FAINTER: 71 MORE NEW W-R STARS

We are continuing a J, K and narrowband imaging survey of 300 deg2 of the plane of the Galaxy, searching for new Wolf–Rayet (W-R) stars. Our survey spans 150° in Galactic longitude and reaches 1°

A near-infrared survey of the inner Galactic plane for Wolf–Rayet stars – III. New methods: faintest WR stars

A new method of image subtraction is applied to images from a J, K, and narrow-band imaging survey of 300 square degrees of the plane of the Galaxy, searching for new Wolf-Rayet stars. Our survey

Eleven New Heavily Reddened Field Wolf?Rayet Stars

We report the results of a medium-narrowband 2 μm line survey covering 5.8 deg2 near the Galactic plane. We confirm 11 new field Wolf–Rayet stars along three lines of sight probing the inner Galaxy,
