The ALMA-ALPAKA survey I: high-resolution CO and [CI] kinematics of star-forming galaxies at z = 0.5-3.5

Understand

Spatially-resolved studies of the kinematics of galaxies provide crucial insights into their assembly and evolution, enabling to infer the properties of the dark matter halos, derive the impact of feedback on the ISM, characterize the outflow motions.

• To date, most of the kinematic studies at z=0.5-3.5 were obtained using emission lines tracing the warm, ionized gas.
• However, whether these provide an exhaustive or only a partial view of the dynamics of galaxies and of the properties of the ISM is still debated.
• Complementary insights on the cold gas kinematics are therefore needed.
