Main Auditorium (Geological Museum, University of Copenhagen)

Invited talk Dust as a tool Dust in the early universe

Speaker

Akio Inoue (Osaka Sangyo University)

Description

First, I will present our recent results from ALMA observations of galaxies in the epoch of reionization, redshifts $z>6$. Second, I will present a method for estimating the dust temperature from far-infrared flux densities, taking the radiative equilibrium and transfer effect into account. Then, I will present a demographics study of dust mass in $z>6$ galaxies and compare the observations with a simple theoretical model. I will pay attention to "dust-free" objects as well as dust-rich ones. Finally, I will discuss the dust mass growth in the interstellar medium and future perspective.
