Outside the Lyman-break box: detecting Lyman continuum emitters at 3.5<z<5.1 with CLAUDS

Identifying non-contaminated sample of high-redshift galaxies with escaping Lyman continuum (LyC) flux is important for understanding the sources and evolution of cosmic reionization. We present CLAUDS u-band photometry of the COSMOS field to probe LyC radiation from spectroscopically confirmed galaxies at z\geq3.5 and outside the standard Lyman-break galaxy colour selection...
