Under modern observations from multiple wavelengths, a complete picture of interstellar medium ISM evolution and star formation is emerging. Observations The Gala satellite maps the distributions and kinematics of stars, which, in many cases, is the missing piece of the puzzle. We combine multi-wavelength observations to establish a comprehensive picture of ISM evolution, to reveal the key physics at work.
In Weather Forecast of the Milky Way: Shear and Stellar feedback determine the lives of Galactic-scale filaments we trace the evolution of the molecular ISM using a sample of Young Stellar Objects (YSO) association --molecular cloud complex (YSO-MC complex), and predict a future configurations of the local ISM.
In Discovery of a coherent, wave-like velocity pattern for the Radcliffe Wave We use the proper motions of Young Stellar Objects (YSOs) anchored inside the clouds to study the kinematic structure of the Radcliffe Wave in terms of vz, and identify a damped, wave-like pattern from the vz space, which we call "velocity undulation".
In Zhou, Li & Chen (2021), we present a first catalog of YSO associations in the solar neighborhood. The sample allows us to study the motion of gas, constrain the origin of molecular cloud turbulence, understand the nature of Giant Filamentary Structures, and identify cloud collision candidates.
