Low-mass stars found in CFHTLS
Listed in IVOA Registry (Virtual Observatory)
We present preliminary results of a new quasar survey being undertaken with multicolor optical imaging from the Canada-France-Hawaii Telescope.
Description
The current data consist of 3.83deg^2^ of imaging in the i' and z' filters to a 10{sigma} limit of z'<23.35. Near-infrared photometry of 24 candidate 5.7<z<6.4 quasars confirms them all to be low-mass stars, including two T dwarfs and four or five L dwarfs.
Photometric estimates of the spectral type of the two T dwarfs are T3 and T6.
