Searching for papers

The standard gateway for finding and accessing astronomy and astrophysics papers is the Astrophysics Data System (ADS) Archive, which is operated by the Smithsonian Astrophysical Observatory.


NGC1052-DF2 is a galaxy in the NGC1052 group, discovered by Karachentsev et al. (2000). We identified it in a search for low surface brightness objects with the Dragonfly Telephoto Array, and obtained follow-up HST, Keck, and Gemini observations. We published two initial papers on the galaxy; one in Nature on its low dark matter content and one in ApJ Letters on its unusual globular cluster population. The Nature paper, in particular, generated intense interest, and we are maintaining a page with background information and links to other people's analyses of our data.


NGC5907 is an edge-on spiral galaxy. In 1998 it was found that the galaxy has a large tidal stream. In 2008 it was found that the stream wraps twice around the galaxy, in a spectacular cork-crew like pattern. In a 2019 paper we presented imaging of this galaxy with the Dragonfly telescope. We provide the fits files of our Dragonfly data, as well as a fits file of a deep amateur image and a little movie, on this page.
