It is largely believed that the dust in this class of galaxies has an external origin in the sense that the host has acquired it through the merger like episode. However, it is interesting to see its existence over a long time despite the fact that the dust grains are destructed over a very short timescale due to the thermal sputtering particularly when are embedded within a large fraction of hot gas. This paper further demonstrates that the interstellar dust in these galaxies is not alone due to the external accretion but internal origin is also contributing substantially to the reservoir of its host. |
