The internal velocity structure within dense gaseous cores plays a crucialrole in providing the initial conditions for star formation in molecularclouds. However, the kinematic properties of dense gas at core scales (~0.01 -0.1 pc) has not been extensively characterized because of instrumentlimitations until the unique capabilities of GBT-Argus became available. Theongoing GBT-Argus Large Program, Dynamics in Star-forming Cores (DiSCo) thusaims to investigate the origin and distribution of angular momenta ofstar-forming cores. DiSCo will survey all starless cores and Class 0protostellar cores in the Perseus molecular complex down to ~0.01 pc scaleswith < 0.05 km/s velocity resolution using the dense gas tracer N$_2$H$^+$.Here, we present the first datasets from DiSCo toward the B1 and NGC 1333regions in Perseus. Our results suggest that a dense core's internal velocitystructure has little correlation with other core-scale properties, indicatingthese gas motions may be originated externally from cloud-scale turbulence.These first datasets also reaffirm the ability of GBT-Argus for studying densecore velocity structure and provided an empirical basis for future studies thataddress the angular momentum problem with a statistically broad sample.
