The abundance of bright galaxies at z>8 can provide key constraints on models galaxy formation and evolution, as the predicted varies greatly when different physical prescriptions for gas cooling star are implemented. We present results a search z=9-10 selected from pure-parallel Hubble Space Telescope imaging programs. include 132 fields observed part Brightest Reionizing Galaxies survey, Infrared Pure Parallel Imaging Extragalactic Survey, WFC3 Spectroscopic survey. These observations cover total 620 sq. arcmin, about 70% which is also covered with Spitzer infrared imaging. identify thirteen candidate in range 8.3
