An automated approach for photometer and dust mass calculation of the Crab nebula

Sauvage, Marc; Nehmé, Cyrine; Kassounian, Sarkis

Ample evidence exists regarding supernovae being a major contributor to interstellar dust. In this work, the deepest far-infrared observations of the Crab Nebula are used to revisit the estimation of the dust mass present in this supernova remnant. Images in filters between 70 and 500 µ m taken by the PACS and SPIRE instruments on-board of t…
