Recent molecular line observations with ALMA in several nearby Seyferts have revealed the existence of tori, and nature gas flows at 10-20 pc scale. At 100 scale, or kpc-scale, previous NOEMA work on gravitational torques had shown that only about one third Seyfert galaxies experienced inflow central fueling, while most cases was stalled rings. higher resolution, i.e. it is possible now to see ...

Stephan's Quintet (SQ) is a nearby compact galaxy group and perfect laboratory for studying the process of evolution through harassment interaction. By analysing kinematics SQ we aim to provide an increased understanding group, history interactions, their cause effect, details regarding physical processes occurring as galaxies interact. We have studied ionised gas stellar using Large Binocular ...
