Abstract:
We apply the supernova (SN) extinction curves to reproduce the
observed properties of SST J1604+4304 which is a young infrared (IR)
galaxy at z∼1. The SN extinction curves used in this work were
obtained from models of unmixed ejecta of Type II supernovae for the
Salpeter initial mass function with a mass range from 8 to 30M☉
or 8 to 40M☉. The effect of dust distributions on the
attenuation of starlight is investigated by performing the χ2
fitting method against various dust distributions. These are the
commonly used uniform dust screen, the clumpy dust screen and the
internal dust geometry. We add to these geometries three scattering
properties, namely, no scattering, isotropic scattering and
forward-only scattering. Judging from the χ2 values, we find
that the uniform screen models with any scattering property provide
good approximations to the real dust geometry.
Description:
Synthetic spectra of stellar populations reddened by dust are modelled
to reproduce the data of SST J1604+4304. This is a young IR galaxy at
z= 1.135 with the characteristic of ULIRGs.
