Description
Galaxies are evolving ecosystems of multiple components which interplay with each other and are distributed over a wide range of spatial scale, from sub-galactic scales up to scales of dark matter halos. Our understanding of the galaxy ecosystems has largely been limited to relatively bright galaxies, however. Other components such as gas of different phases as well as dwarf galaxies with stellar mass below about 10^9 solar mass are still poorly understood. I will talk about our recent studies of the abundance, formation and quenching of low-z dwarf galaxies with stellar mass down to ~10^7 solar mass. I will also talk about our measurements of the cool gas and atomic gas content in low-z dark matter halos.
