The Extended HST Supernova Survey: The Rate of SNe Ia at z>1.4 Remains Low (2008)

Dahlen, Tomas, Strolger, Louis-Gregory, Riess, Adam G.

We use the HST ACS imaging of the two GOODS fields during Cycles 11, 12, and 13 to derive the Type Ia supernova rate in four redshift intervals in the range 0.21.4 appears to contradict these...

New Hubble Space Telescope Discoveries of Type Ia Supernovae at z > 1: Narrowing Constraints on the Early Behavior of Dark Energy (2006)

Riess, Adam G., Strolger, Louis-Gregory, Casertano, Stefano, Ferguson, Henry C., Mobasher, Bahram, Gold, Ben, ...

We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to trace the history of cosmic expansion over the last 10 billion years. These objects,...

Optical and near-infrared observations of the peculiar Type la supernova 1999ac (2006)

Phillips, Mark M., Krisciunas, Kevin, Suntzeff, Nicholas B., Abraham, R. G., Beckett, M. G., Bonati, Marco, ...

We present 39 nights of optical photometry, 34 nights of IR photometry, and 4 nights of optical spectroscopy of the Type la supernova 1999ac. This supernova was discovered 2 weeks before maximum...

Optical and near-infrared observations of the peculiar Type la supernova 1999ac (2006)

Phillips, Mark M., Krisciunas, Kevin, Suntzeff, Nicholas B., Abraham, R. G., Beckett, M. G., Bonati, Marco, ...

We present 39 nights of optical photometry, 34 nights of IR photometry, and 4 nights of optical spectroscopy of the Type la supernova 1999ac. This supernova was discovered 2 weeks before maximum...

The Deepest Supernova Search is Realized in the Hubble Ultra Deep Field Survey (2005)

Strolger, Louis-Gregory, Riess, Adam G.

The Hubble Ultra Deep Field Survey has not only provided the deepest optical and near infrared views of universe, but has enabled a search for the most distant supernovae to z~2.2. We have found four...

High Redshift Supernova Rates (2004)

Dahlen, Tomas, Strolger, Louis-Gregory, Riess, Adam G., Mobasher, Bahram, Chary, Ranga-Ram, Conselice, Christopher J., ...

We use a sample of 42 supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope as part of the Great Observatories Origins Deep Survey to measure the rate of core...

Type Ia Supernova Discoveries at z>1 From the Hubble Space Telescope: Evidence for Past Deceleration and Constraints on Dark Energy Evolution (2004)

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

We have discovered 16 Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to provide the first conclusive evidence for cosmic deceleration that preceded the current...

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...
