Speaker:Prof. 潘彥丞(PAN, Yen-Chen) 國立中央大學天文研究所/Graduate Institute of Astronomy, National Central University Title:Understanding type Ia supernovae through their host galaxies Abstract:Type Ia supernovae (SNe Ia) are exceptionally bright explosions, and their calibrateable brightness make them powerful standard candles in measuring the distance and probing the cosmic expansion. In fact, no SN Ia progenitors have ever been identified directly. The unknown nature of progenitor system could complicate their usage in cosmology. Alternatively, host-galaxy study of SN Ia has been a profitable route to probe the nature of the progenitor system and explosion mechanism. In this talk, I will show how we can take advantage of the relation between host parameters and SN Ia properties to shed the light on their progenitor systems and potential evolution with the redshift.
