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…
The Dragonfly Wide Field Survey. II. Accurate Total Luminosities and Colors of Nearby Massive Galaxies and Implications for the Galaxy Stellar Mass Function
Tim B. Miller, Pieter van Dokkum, Shany Danieli +8
Stellar mass estimates of massive galaxies are susceptible to systematic errors in their photometry, due to their extended light profiles. In this study we use data from the Dragon…
A missing outskirts problem? Comparisons between stellar halos in the Dragonfly Nearby Galaxies Survey and the TNG100 simulation
Allison Merritt, Annalisa Pillepich, Pieter van Dokkum +4
Low surface brightness galactic stellar halos provide a challenging but promising path towards unraveling the past assembly histories of individual galaxies. Here, we present detai…
The Dragonfly Wide Field Survey. I. Telescope, Survey Design and Data Characterization
Shany Danieli, Deborah Lokhorst, Jielai Zhang +11
We present a description of the Dragonfly Wide Field Survey (DWFS), a deep photometric survey of a wide area of sky. The DWFS covers 330 in the equatorial GAMA fie…
Multi-resolution filtering: an empirical method for isolating faint, extended emission in Dragonfly data and other low resolution images
Pieter van Dokkum, Deborah Lokhorst, Shany Danieli +5
We describe an empirical, self-contained method to isolate faint, large-scale emission in imaging data of low spatial resolution. Multi-resolution filtering (MRF) uses independent…
The Dragonfly Edge-on Galaxies Survey: Shaping the outer disc of NGC 4565 via accretion
Colleen Gilhuly, David Hendel, Allison Merritt +6
We present extremely deep imaging of the well-known edge-on galaxy NGC 4565 (the "Needle Galaxy"), observed as part of the Dragonfly Edge-on Galaxies Survey. Our imaging traces sta…
