The Dragonfly Spectral Line Mapper: Design and First Light
Seery Chen, Deborah M. Lokhorst, Jeff Shen +4
The Dragonfly Spectral Line Mapper (DSLM) is the latest evolution of the Dragonfly Telephoto Array, which turns it into the world's most powerful wide-field spectral line imager. T…
Distributed Aperture Telescopes and the Dragonfly Telephoto Array
Roberto G. Abraham, Pieter G. van Dokkum, Deborah M. Lokhorst +4
Telescope arrays allow high-performance wide-field imaging systems to be built more quickly and at lower cost than conventional telescopes. Distributed aperture telescopes (the pre…
The pathfinder Dragonfly Spectral Line Mapper: Pushing the limits for ultra-low surface brightness spectroscopy
Deborah M. Lokhorst, Seery Chen, Imad Pasha +4
The pathfinder Dragonfly Spectral Line Mapper is a distributed aperture telescope based off of the Dragonfly Telephoto Array with additional instrumentation (the Dragonfly "Filter-…
A low-cost ultraviolet-to-infrared absolute quantum efficiency characterization system of detectors
Ajay S. Gill, Mohamed M. Shaaban, Aaron Tohuvavohu +8
We present a low-cost ultraviolet to infrared absolute quantum efficiency detector characterization system developed using commercial off-the-shelf components. The key components o…
Stellar halos from The Dragonfly Edge-on Galaxies Survey
Colleen Gilhuly, Allison Merritt, Roberto Abraham +6
We present the primary results from the Dragonfly Edge-on Galaxies Survey (DEGS), an exploration of the stellar halos of twelve nearby ( Mpc) edge-on disc galaxies with the…
A giant shell of ionized gas discovered near M82 with the Dragonfly Spectral Line Mapper pathfinder
Deborah Lokhorst, Roberto Abraham, Imad Pasha +8
We present the discovery of a giant cloud of ionized gas in the field of the starbursting galaxy M82. Emission from the cloud is seen in H and [NII]6583 in data obtained thou…
