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 back in 2018 we set up a page with background information and links to other people's analyses of our data. We are keeping the link as a record; thanks to wonderful new data from HST and ground-based telescopes the debate about the essential aspects of the galaxies (their masses and distances) has now been settled.
This is the 40-orbit HST/ACS image that was used in Zili Shen's 2021 TRGB analysis:
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.
