Speaker
Description
The interaction of galaxies play an important role in fueling the SMBHs and accelerating their growth. In this presentation, I will first introduce the techniques that we have used to identify mergers in HSC images, namely, the morphological asymmetry parameter. With over 2400 type 1 quasars between 0.2<z<0.8, we found that only the brightest quasars (log L_bol>44.5 erg/s) have an excess of merger ratio compared to inactive galaxies at the same stellar mass and redshift. My presentation will also cover a special phase of quasar mergers when both of the SMBHs are activated simultaneously, thus form a dual quasar. We have been running a five-year program searching for dual quasars in HSC footprint, and multi-wavelength follow-ups to study the properties of the confirmed pairs. Both projects will be significantly extended in the LSST era, I will discuss about the scientific questions we expect to learn from these quasar mergers.
