The transient universe as seen by iPTF and ZTF

I’m attending The transient universe as seen by iPTF and ZTF meeting in Stockholm Sweden. Discussion will range from circumstellar interaction, cosmology, and asteroid science to details about the iPTF, and ZTF surveys. I’m keen to learn about all anticipated used of SED Machine!
