Title

Molecular gas observations toward the Local Group and the outer Milky Way
 

Scientific Rationale

   The unified understanding the formation and evolution of molecular gas, stars, star clusters, and galaxies from the early to the present universe is one of the greatest challenges in astrophysics. Nearby galaxies, including the Large/Small Magellanic Clouds (LMC/SMC) and the outer region of the Milky Way (MW), are ideal laboratories to explore the parameter space with a high spatial resolution, which is not possible by observations toward the MW alone. Especially, observations of low-metallicity environments provide a unique opportunity to investigate the formation and evolution of the astronomical objects in the early universe. Recent observational studies of the LMC and M33 have been revealing that kpc-scale gas flows, possibly formed by interactions with other galaxies and the motion of spiral arms, trigger the formation of molecular filaments with a typical width of 0.1 pc as well as high-mass stars. With a wide spatial dynamic range from kpc down to sub-pc scale, observations across galaxies in their entirely using multiple instruments become an important focus of attention. Moreover, recent ALMA surveys in the Magellanic Clouds start to unveil the dynamical and chemical properties of high-mass star formation at low-metallicity environments.
   In this workshop, we aim to share our current understanding regarding star formation in low-metallicity environments obtained by recent observational studies, and then discuss what we can do in the near future (e.g., ALMA Cycle 8) by incorporating theoretical knowledge of the early universe.
