Abstract (from CDS):

Sensitive 21 cm HIobservations have been made with the Green Bank Telescope toward the newly-discovered Local Group dwarf galaxy Hydra II, which may lie within the leading arm of the Magellanic Stream. No neutral hydrogen was detected. Our 5σ limit of MHI≤210M☉ for a 15km/s linewidth gives a gas to luminosity ratio MHI/LV≤2.6x10–2M☉/L☉. The limits on HImass and MHI/LV are typical of dwarf galaxies found within a few hundred kpc of the Milky Way. Whatever the origin of Hydra II, its neutral gas properties are not unusual.
