The Maybe Stream: A Possible Cold Stellar Stream in the Ultra-Diffuse
  Galaxy NGC1052-DF2
  We report tentative evidence for a cold stellar stream in the ultra-diffuse
galaxy NGC1052-DF2. If confirmed, this stream (which we refer to as "The Maybe
Stream") would be the first cold stellar stream detected outside of the Local
Group. The candidate stream is very narrow and has an unusual and highly curved
shape.
