Wide-band cm-Wavelength Observations with SKA
H. Nakanishi et. al.
The international project SKA (Square Kilometer Array) has the following four primary characteristics (1) high sensitivity, (2) high spatial resolution, (3) wide field of view, (4) wide band. We Japan SKA consortium members are now interested in the fourth characteristic of 'wide band' in terms of both science and engineering. I would like to talk about astronomy achieved with wide band receiver system and like to report our recent activities.
