Mid-infrared spectral evidence for a luminous dust enshrouded source in Arp220
H. W. W. Spoon, A. F. M. Moorwood, D. Lutz +3
We have re-analyzed the 6-12 micron ISO spectrum of the ultra-luminous infrared galaxy Arp220 with the conclusion that it is not consistent with that of a scaled up version of a ty…
