PIC simulation results of pulsar magnetospheres of PSR J1856-3754. The picture is divided into two parts and there are several parts for each pulsar: the top row shows a slice of the entire simulation in the plane at z = 0 for the three magnetic-field directions and the middle row shows the electromagnetic field around the radius of the neutron star zoomed in on the top panel. Both panels show the magnetic fields in the order Bx, By, and Bz. The left panel of the bottom row shows the data used for the examination of the pulsar integral profile and the results of the comparison between the pulsar profile generated by our PIC simulation. In contrast, the right panel shows the pulsar parameters and a schematic of the GWs crossing the magnetic field in the direction of the observational LOS.
