Dust in Supernovae; Formation and Evolution (2009)
Kozasa, Takashi, Nozawa, Takaya, Tominaga, Nozomu, Umeda, Hideyuki, Maeda, Keiichi, Nomoto, Ken'ichi
Core--collapsed supernovae (CCSNe) have been considered to be one of sources of dust in the universe. What kind and how much mass of dust are formed in the ejecta and are injected into the...

We investigate the evolution of dust formed in Population III supernovae (SNe) by considering its transport and processing by sputtering within the SN remnants (SNRs). We find that the fates of dust...
Extinction curves flattened by reverse shocks in supernovae (2008)
Hirashita, Hiroyuki, Nozawa, Takaya, Takeuchi, Tsutomu T., Kozasa, Takashi
We investigate the extinction curves of young galaxies in which dust is supplied from Type II supernovae (SNe II) and/or pair instability supernovae (PISNe). Since at high redshift (z>5), low-mass...

Nozawa, Takaya, Kozasa, Takashi, Habe, Asao, Dwek, Eli, Umeda, Hideyuki, Tominaga, Nozomu, ...
We investigate the evolution of dust that formed at Population III supernova (SN) explosions and its processing through the collisions with the reverse shocks resulting from the interaction of the SN...
A model for the infrared dust emission from forming galaxies (2006)
Takeuchi, Tsutomu T., Ishii, Takako T., Nozawa, Takaya, Kozasa, Takashi, Hirashita, Hiroyuki
In the early epoch of galaxy evolution, dust is only supplied by supernovae (SNe). With the aid of a new physical model of dust production by SNe developed by Nozawa et al. (2003) (N03), we...
Dust Destruction in the High-Velocity Shocks Driven by Supernovae in the Early Universe (2006)
Nozawa, Takaya, Kozasa, Takashi, Habe, Asao
We investigate the destruction of dust grains by sputtering in the high-velocity interstellar shocks driven by supernovae (SNe) in the early universe to reveal the dependence of the time-scale of...

We investigate the extinction curves of young galaxies in which dust is supplied from Type II supernovae (SNe II) and/or pair instability supernovae (PISNe). We adopt Nozawa et al. (2003) for...
