Using deep 21?cm H I data from the Green Bank Telescope we have detected an 18.3?kpc long gaseous extension associated with the starbursting dwarf galaxy IC 10. The newly found feature stretches 1.?3 to the northwest and has a large radial velocity gradient reaching to ~65?km s?1 lower than the IC 10 systemic velocity. A region of higher column density at the end of the extension that possesses a coherent velocity gradient (~10?km s?1 across ~26') transverse to the extension suggests rotation… Expand
