Photon vs Energy Magnitude Systems and the Measurement of the Cosmological Parameters
Alex Kim, Peter Nugent
The relative brightnesses of standard candles have long been known to be potentially powerful probes of distance. The distance modulus, the difference between observed and absolute…
Using the Supernova / Acceleration Probe (SNAP) to Search for Microlensing Events Towards the LMC
David S. Graff, Alex Kim
Microlensing experiments today have a tantalizing result; they have detected an excess of microlensing events beyond what is expected from known stellar populations. These events c…
A Review of the High-Redshift Supernova Searches
A. G. Kim
Observations show that Type Ia Supernovae (SNe Ia) form a homogeneous class of objects. They share similar spectroscopic evolution, light-curve shapes, and peak absolute magnitudes…
The Type Ia Supernova Rate at z ~ 0.4
R. Pain, I. Hook, S. Perlmutter +23
We present the first measurement of the rate of Type Ia supernovae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as desc…
K Corrections For Type Ia Supernovae and a Test for Spatial Variation of the Hubble Constant
A. Kim, S. Deustua, S. Gabi +23
Cross-filter K corrections for a sample of "normal" Type Ia supernovae (SNe) have been calculated for a range of epochs. With appropriate filter choices, the combined statistical a…
Scheduled Discoveries of 7+ High-Redshift Supernovae: First Cosmology Results and Bounds on q_0
S. Perlmutter, S. Deustua, S. Gabi +23
Our search for high-redshift Type Ia supernovae discovered, in its first years, a sample of seven supernovae. Using a "batch" search strategy, almost all were discovered before max…
