Selection of high-z supernova candidates.
DAHLEN T. and GOOBAR A.
Abstract (from CDS):
Using Monte Carlo simulations we construct criteria for selecting galaxies in well-defined redshift bands. For example, with a selection criterion using B-R and R-I colors we are able to pick out potential host galaxies for which z≥0.85 with an 80% confidence level and with a selection efficiency of 64%-86%. The method was successfully tested using real observations from the Hubble Deep Field.
Similarly, we show that the magnitude and colors of the supernova discovery data can be used to constrain the redshift. With a set of cuts based on V-R and R-I in a search to mI∼25, supernovae at z∼1 can be selected in a redshift interval σz≤0.15.
