Abstract:
Pisces A and Pisces B are the only two galaxies found via optical
imaging and spectroscopy out of 22 HI clouds identified in the GALFAHI
survey as dwarf galaxy candidates.
We derive the HI content and kinematics of Pisces A and B.
Our aperture synthesis HI observations used the seven-dish Karoo Array
Telescope (KAT-7), which is a pathfinder instrument for MeerKAT, the
South African precursor to the mid-frequency Square Kilometre Array
(SKA-MID).
Description:
The observations were obtained with the seven-dish KAT-7 array,
located close to the South African SKA core site in the Northern
Cape's Karoo desert region.
The data were collected between 2014 November 27 and 2014 December 16.
