Selection and Discovery of Quasars at High Redshift Through Infrared and Optical Imaging
Abstract
Presented here are the results designed to aid in the computing of the space density of quasars at 4.8 < z < 6 by removing late type stars from the Big Throughput Camera (BTC40) search for quasar candidate list. The BTC40 survey is a multicolor survey for quasars at high redshift, which proved to be successful at finding quasars, but due to faintness of the candidates and the presence of contaminates, spectroscopy could not be completed for the entire survey. Here, J-band targeted imaging data was added in an attempt to refine the candidate list, for follow-up on an 8m class telescope. Complimenting the new data set is modeling of quasar spectra for various redshifts. This work was funded by an NSF ADVANCE Fellowship.
