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…
Imaging and Demography of the Host Galaxies of High-Redshift Type Ia Supernovae
Benjamin F. Williams, Craig J. Hogan, Brian Barris +24
We present the results of a study of the host galaxies of high redshift Type Ia supernovae (SNe Ia). We provide a catalog of 18 hosts of SNe Ia observed with the Hubble Space Teles…
Cosmological Results from High-z Supernovae
John L. Tonry, Brian P. Schmidt, Brian Barris +22
The High-z Supernova Search Team has discovered and observed 8 new supernovae in the redshift interval z=0.3-1.2. These independent observations, confirm the result of Riess et al.…
