Dust content of core-collapse supernova hosts

TL;DR

This study investigates the dust content of core-collapse supernova host galaxies at redshifts 0.1-0.6 using 250GHz observations, finding they are typical of local galaxies with no significant dust emission detected.

Contribution

First to provide submillimetre dust mass limits for CCSN host galaxies at these redshifts, showing they are not dust-rich or extreme compared to typical galaxies.

Findings

No significant dust emission detected in the sample.

Dust mass upper limits are consistent with normal galaxy populations.

CCSN hosts are not extreme in millimetre wavelengths.

Abstract

We study a small sample of z=0.1-0.6 core-collapse supernova (CCSN) host galaxies. Continuum observations at 250GHz have been performed with MAMBO at the IRAM-30m telescope. None of these sources has been detected and the error-weighted mean flux is 0.25+/-0.32 mJy. Upper limits on their dust masses are derived and the corresponding sample mean corresponds to 1.4 +/- 2.2 x 10^8 Msol. These results are comparable with previous submillimetre observations of SN-Ia hosts performed by Farrah et al. and by Clements et al. We conclude that CCSN hosts are not extreme at millimetre wavelengths, and as confirmed with the optical luminosities of a subset of our sample, they are typical of the local galaxy population.
