Surveys for Distant SNe

I am co-PI (with Nao Suzuki) of the SUbaru Supernovae with Hubble Infrared (SUSHI) program. We are more than doubling the number of well-measured, distant (redshift >~ 1.1) supernovae Ia to significantly improve our measurements of the expansion history of the Universe.

Other work I have done with distant SNe includes:

Gravitationally amplified SNe in Cluster Lensing And Supernova survey with Hubble (CLASH)

Lensed Type Ia supernovae as probes of cluster mass models

and record-breaking SNe Ia

The Discovery of a Gravitationally Lensed Supernova Ia at Redshift 2.22

Precision Measurement of The Most Distant Spectroscopically Confirmed Supernova Ia with the Hubble Space Telescope
