【Rationale】
Galaxies are multicomponent system mainly consisting of dark matter (DM), stars and interstellar medium (mainly cold gas). The evolution of DM and stellar component have been investigated by means of numerical simulations and large galaxy surveys at optical and near-infrared wavelengths. However, the evolution of the cold gas component (molecules/atoms) remains poorly explored. The redshift range of z<~2 is the era in which the current Hubble sequence emerges, as well as the era for disk galaxies converting their cold gas to stars then developing their galactic disks. Further, one can expect larger and homogeneous data set of stellar/ionized gas/atomic gas of galaxies with the new-generation instruments such as HSC, PFS, and SKA. To understand the galaxy evolution at z<~2, namely the second half of the cosmic history, it is important to investigate the molecular gas component statistically, since it links the information of other components (stellar/ionized gas/atomic gas) of galaxies.
We are now planning ALPACA survey (ALMA Large Proposal of gAlactic Cold gAs) aiming at investigating statistical properties ("amount", such as cold gas mass function) and/or detailed "spatial distribution" and "kinematics" of molecular gas of galaxies at z<~2. To design a desirable survey that can provide scientifically important and versatile data, we must list up the missing pieces for understanding the galaxy evolution, and discuss their importance. The workshop consists of invited review talks and contributed talks. Sufficient time will be spared for discussions. We are willing to discuss galaxy evolution regardless of the means (numerical simulations/semi-analytic models/observations at all wavelengths)!
