Formation and evolution of galaxies and clusters of galaxies based (mainly) on millimeter and sub-millimeter observations.
Dense interstellar medium and their relation to activities in galaxies, including
Seyfert galaxies, starburst galaxies, barred galaxies,
early-type galaxies, radio galaxies, quasars,
submm galaxies, Ly alpha emitters, Ly alpha brobs, H alpha emitters,
GRB host galaxies.
