| Abstract: |
Mergers play important roles in triggering the most active
objects in the universe, including (U)LIRGs and QSOs. However, whether
they are also important for the total stellar mass build-up in
galaxies in general is unclear and controversial. Answer to that
question depends on the merger rate and on the average strength of
merger induced star formation. In this talk, I will review studies on
spatial density and sSFR enhancement of local mergers found in
NIR/optical selected pair samples. In line with the current literature
on galaxy formation/evolution, special attention will be paid on the
dependence of the local merger rate and the sSFR enhancement on four
fundamental observables: (1) stellar mass, (2) mass ratio, (3) separation,
and (4) environment. |
