Specific Star Formation Rate as a function of Galaxy Stellar Mass for underluminous supernovae galaxies sample

Specific Star Formation Rate as a function of Galaxy Stellar Mass. The open squares are MUNICS galaxies, filled squares represent FDF galaxies and the crosses show SDSS galaxies chosen to match the photometric limits of the MUNICS sample (A. E. Bauer et al, 2005).

The dotted line is the quiescent cut. All galaxies below are regarded as

quiescent.

Our sample galaxies all lie above this quiescent threshold.

Our host galaxies are likely not elliptical or lenticular.

Main Sequence Galaxies

Starburst galaxies

Not starburst galaxies

From the evidence, the most likely galaxy type is a star-forming spiral, consistent with the host galaxies of suspected type Iax progenitors
