Constraining Type Ia Supernova Delay Time with Spatially Resolved Star
  Formation Histories
  We present the delay time distribution (DTD) estimates of Type Ia supernovae
(SNe~Ia) using spatially resolved SN~Ia host galaxy spectra from MUSE and
MaNGA. By employing a grouping algorithm based on k-means and earth mover's
distances (EMD), we separated the host galaxy star formation histories (SFHs)
into spatially distinct regions and used maximum likelihood method to constrain
the DTD of SNe Ia progenitors. When a power-law model of the form
$DTD(t)\propto t^{s} (t>\tau)$ is used, we found an SN rate decay slope
$s=-1.41^{+0.32}_{-0.33}$ and a delay time $\tau=120^{+142}_{-83} Myr$ .
Moreover, we tested other DTD models such as a broken power law model and a
two-component power law model, and found no statistically significant support
to these alternative models.
