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 supernovae were...

Identification of Type Ia Supernovae at Redshift 1.3 and Beyond with the Advanced Camera for Surveys on HST (2003)

Riess, Adam G., Strolger, Louis-Gregory, Tonry, John, Tsvetanov, Zlatan, Casertano, Stefano, Ferguson, Henry C., ...

We present discoveries of SNe Ia at z > 1 and the photometric diagnostic used to discriminate them from other types of SNe detected during the GOODS Hubble Space Telescope Treasury program with the...

Discovery of a Methane Dwarf from the IfA-Deep Survey (2002)

Liu, Michael C., Wainscoat, Richard, Martin, Eduardo L., Barris, Brian, Tonry, John

We present the discovery of a distant methane dwarf, the first from the Institute for Astronomy (IfA) Deep Survey. The object ("IfA 0230-Z1") was identified from deep optical I and z'-band imaging,...

We present photometric observations of an apparent Type Ia supernova (SN Ia) at a redshift of ~1.7, the farthest SN observed to date. SN 1997ff, was discovered in a repeat observation by the HST of...

The farthest known supernova: Support for an accelerating universe and a glimpse of the epoch of deceleration (2001)

Riess, Adam G., Nugent, Peter E., Schmidt, Brian P., Tonry, John, Dickinson, Mark, Gilliland, Ronald L., ...

We present photometric observations of an apparent Type Ia supernova (SN Ia) at a redshift of approximately 1.7, the farthest SN observed to date. The supernova, SN 1997, was discovered in a repeat...
