Description
Paleo-detectors are a proposed experimental technique in which one would search for traces of recoiling nuclei in minerals up to $1 \mathrm{\,Gyr}$ old. Even reading out a relatively small target sample ($100 \mathrm{\,g}$), would therefore allow one to search for very rare events thanks to the large exposure, $\epsilon \sim 100 \mathrm{\,g\,Gyr} = 105 \mathrm{\,t\,yr}$. I will show how paleo-detectors can be used to measure the nuclear recoils induced by neutrinos from galactic core collapse supernovae. In particular, I will show that it is possible to make a direct measurement of the average core collapse supernova rate in the Milky Way. Paleo-detectors will also contain information about the time-dependence of the local supernova rate over the past $\sim 1 \mathrm{\,Gyr}$. Measuring such a time evolution would provide a direct determination of the local star formation history. In addition I will investigate possible deviations to the diffuse supernova Neutrino background that might be observable with Super-Kamiokande.
