Title: An Ultra-low Surface Brightness Telescope Detects Ancient Nova Shells, Intergalactic Matter… and Dark Matter Filaments?
Abstract:
The currently-operational Condor Array Telescope is detecting optical low surface brightness features >10X fainter than 4-8 meter class telescopes. I’ll describe how this is done, and then show ancient recurrent nova ejecta larger than supernova remnants; a starless hydrogen cloud in the M81 group; and filamentary emission-line structures at redshift z = 0.13 that may trace dark matter filaments.
