" Infrared selected AGNs and prospects with HSC "

Yu-Yen Chang


We focus on mid-infrared selected obscured AGNs and fit their optical to far-infrared photometry by the state-of-art SED technique. We derive their stellar masses, star formation rates, dust properties, AGN contribution, obscuration, and the morphologies of their hosts through HST images. Comparing to normal star-forming galaxies at similar redshift and stellar mass, AGN hosts are more compact and their merger fraction is not higher at z~1. We postulate that obscured AGNs are hosted by galaxies experiencing a mode of compaction, as recently discussed in the literature from hydrodynamic simulations of gas-rich disk galaxy formation. I will also talk about my recent plan related to the HSC survey.

Seminars are also held at JAC, CFHT, and IfA.
