The origin of pulsar radio emission is one of the old puzzles in theoretical astrophysics. In this Letter. we present a global kinetic plasma simulation that shows from first principles how and where radio emission can be produced in pulsar magnetospheres. We observe the self-consistent formation of electric gaps that periodically ignite electron-positron discharge. https://www.redeturismobrasil.com/product-category/autographed-framed-football-jerseys/
