Cold dust in ( some ) high-z supernova host galaxies

We present deep submillimetre photometry for 14 galaxies at z=0.5 that are hosts of type 1a supernovae, with the aim of examining the evolution of dust mass and extinction in normal galaxies. We combine these results with our previous observations of 17 z∼0.5 SN1a hosts to look for any evolution in the dust content of normal galaxies between z=0 and z=0.5… CONTINUE READING
