23 High Redshift Supernovae from the IfA Deep Survey: Doubling the SN Sample at z>0.7

Brian J. Barris, John Tonry, Stephane Blondin +29

We present photometric and spectroscopic observations of 23 high redshift supernovae spanning a range of z=0.34-1.03, 9 of which are unambiguously classified as Type Ia. These supe…
