The Nature of Supernovae Progenitors and Interstellar Dust: Light Echoes Around Type Ia Supernovae (2017-06-08)Incomprehensive knowledge on dust is hindering our study of the universe. For example, the type Ia supernovae (SNe) cosmology requires better estimation of interstellar extinction to reduce systematic uncertainties. The ...
