An illustration of the Doughnut Method for a SN Ia host.

Our paper on type Ia supernova spatial distributions and how they can be used to age date SNe Ia has been accepted for publication in ApJ. You can read a draft of it here.

Prompt Ia Supernovae are Significantly Delayed

This is the paper wherein we develop a new observational technique that builds on previous work by Andy Fruchter and others.

Evan is a member of the LSST team, and so now our “doughnut method” for constraining type Ia SNe will be a small part of the science goals of the LSST.

To read more about the “doughnut method“, check out our paper on it, Prompt Ia Supernovae are Significantly Delayed which has been submitted to ApJ Letters.
