    Dust as a tool
    Review Talk

    Early dust enrichment is believed to occur on very short timescales following the first supernova explosions. The efficiency of this process and the nature of the first dust have a large impact on early star formation. Molecule formation on the surface of dust grains promotes gas cooling, increasing the star formation efficiency. In the densest part of collapsing pre-stellar clouds dust-driven...

  2. 19. Dust and elements in the epoch of reionization
    Akio Inoue (Osaka Sangyo University)

    Dust as a tool
    Invited talk

    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...

  3. 81. The dust-to-stellar mass ratio, a key-tool for probing galaxy evolution from z~0 up to z~6

    Dust as a tool
    Contributed talk

    Over the last decade, the IR Herschel satellite has allowed to trace the
    dust budget up to z ∼4, and the recent ALMA facility
    is extending the measurement of the dust production to even early times.
    This has rendered particularly urgent the issue of explaining how
    the dust mass in galaxies is related to other key galaxy-integrated quantities, i.e. stellar mass andstar-formation rate.
    In the...
